- Cytomel is a potent T3 thyroid medication that can significantly boost metabolism and support weight loss in patients who are genuinely T3-deficient, but it's not appropriate for everyone and requires careful dosing.
- Simply taking Cytomel won't produce weight loss without concurrent attention to diet, exercise, and other metabolic factors, just like any metabolism booster needs lifestyle support to work.
- T3 medication carries risks including heart palpitations, anxiety, and potential thyroid suppression if dosed incorrectly, so this requires working with a provider who understands T3 physiology.
- Some patients see dramatic improvements on T3 while others experience no benefit or side effects, making individual assessment and trial-and-adjust dosing essential to find your optimal dose.
- Cytomel is best considered as part of a comprehensive thyroid optimization plan after you've ruled out other deficiencies and hormonal imbalances that might be the real culprit in your weight struggle.
Cytomel may be one of the most effective thyroid medications on the market.
And because your thyroid plays a role in regulating your metabolism, it also happens to be one of the best for helping with weight loss.
Does that mean that every thyroid patient should be taking it?
No!
But it definitely means that it can and should be considered, especially if you are someone who is doing everything else right and still struggling to lose weight.
Before you run out and start taking it, here’s what you need to know:
How Cytomel Can Help You Lose Weight
Looking at available research on physiology, you can say with some degree of certainty that your thyroid controls about 50-60% of your basal metabolic rate (1) (pinpointing an exact amount is more difficult than you might think).
This is the rate at which you burn calories at rest and is one of the most important values when determining whether or not you will be successful when losing weight (2).
People with a higher metabolism will lose weight faster and more easily compared to someone with a lower metabolism. It’s pretty simple.
Because Cytomel contains the most powerful thyroid hormone, T3, it’s considered stronger when compared to more standard thyroid medications like levothyroxine.
So if you take it instead of levothyroxine, you are providing a much more significant boost to your thyroid and, therefore, your metabolism.
The end result? More weight loss.
But on top of this, thyroid patients who take Cytomel also see a benefit to fluid retention which is another common cause of weight gain among this population.
When you combine the increase in metabolism with a loss in water weight, many thyroid patients do see a drop on the scale when they start taking Cytomel even without diet and exercise.
Understanding how it works is fairly simple. Understanding how to use it safely is slightly more complex.
How To Use Cytomel Safely
Because Cytomel is stronger than T4-only thyroid medications, there are a few extra steps that should be taken if you plan on using it.
As someone with a thyroid problem, you’re probably well familiar with the need for thyroid lab tests which should be assessed regularly if you are taking any sort of thyroid medication.
This recommendation still applies if you are using Cytomel, but on top of the standard tests (TSH and free T4), a few extra are required.
These lab tests include:
These are not lab tests that are generally ordered by most doctors so you will likely need to specifically request them.
But when taking Cytomel, they are important to track to ensure you are never taking more than what would be considered normal or physiologic.
Again, because T3 is so powerful, taking more than you need can lead to problems such as bone loss (3) or even heart problems (4).
Don’t let these symptoms scare you because they are preventable as long as your dose is normal.
On top of these extra lab tests, you’ll also want to keep track of a few other metrics including:
- Your resting heart rate (5) – Your resting heart rate should stay under 70-80 beats per minute when taking Cytomel. If you see it increasing into the 90s or even the low 100s then your dose is too high.
- And your basal body temperature (6) – Your body temperature should never exceed 98.6 degrees. If you see it increasing higher than this then it’s an indication you are pushing yourself into a hyperthyroid state.
You don’t have to keep an eye on your body temperature or resting heart rate, but I do find them to be very helpful especially when you first start taking Cytomel and are trying to optimize your dose.
Once you determine if using Cytomel is right for you the next step is to figure out how much you need.
Cytomel Dosing For Weight Loss
Like any other hormone in the body, Cytomel isn’t going to help unless you are taking enough of it.
The balance that you must strike is finding a dose that is not too high, as to cause unwanted side effects, and not too low, as to cause no benefit at all, but somewhere in between.
For most people, this dose will be somewhere between 5 mcg and 20 mcg per day.
This dosing recommendation is based loosely on the physiologic production of T3 from the healthy thyroid gland which is around 10-25 mcg per day.
By the way, the healthy thyroid gland also produces around 90 to 100 mcg of T4 each day, which will come into play in just a minute so keep this value in mind.
If we start on the basis that we are trying to mimic what the healthy thyroid gland produces, we will automatically minimize the risk of unwanted side effects while maximizing benefits.
This is because we already know that the healthy body can tolerate this dose.
This range of 5 to 20 mcg is just a guideline, though, as there will be people who need more or less.
For perspective, I’ve seen people use as little as 1-2 mcg of T3 per day or as high as 70 mcg per day.
If you do decide to start taking Cytomel then make sure that you start at a low dose and slowly increase your dose (titrate) over time.
For instance:
A typical starting dose may be 5 mcg which then increases by 5 mcg every 10-14 days.
It’s been my experience that this slow increase over time allows for the body to adapt to the T3 thyroid hormone which further minimizes the risk of side effects.
And in the event that side effects do occur, you can always back down on your dose to a dose that previously worked for you.
Bottom line? Cytomel does come with some extra baggage in the form of side effects but the tradeoff is that it’s much more powerful.
Here’s how it compared to some other thyroid medications:
Cytomel vs Synthroid For Weight Loss
โAs far as weight loss is concerned, Cytomel will be superior to levothyroxine and Synthroid in almost every instance.
In terms of magnitude, T3 is roughly 80 to 100 times more potent than T4 which is what levothyroxine contains.
But instead of thinking about which one is better, I think it’s more useful to think of them as a complementary pair.
While it is true that some people do benefit from using only T3, referred to as T3 monotherapy, many people do even better on a combination of T4 and T3.
And it’s this combination of T4 and T3 that I think you will really start to see significant benefits to your health and weight.
In fact, I would say the majority of thyroid patients need some combination of T4, T3, and T2 because this mimics the natural production of thyroid hormone from your thyroid gland.
And if we look at someone with a healthy thyroid gland, we see that their metabolism and weight are both normal.
From a practical standpoint, this looks like taking two different medications at the same time:
Both Cytomel and Synthroid, in this case.
This is the case for Synthroid and levothyroxine but what about NDT?
Cytomel vs NDT For Weight Loss
This one is a little different than the levothyroxine example because NDT formulations, like Armour Thyroid and NP thyroid, come with both T4 and T3 built into them.
NDT contains a static combination of both T4 and T3 to the tune of 38 mcg of T4 and 9 mcg of T3 in each unit (termed a grain).
This ratio puts us pretty close to the 80:20 ratio that was mentioned previously when combining levothyroxine and Cytomel together, so they are very similar.
For this reason, the answer regarding which one is better has more to do with dose and personal preference than anything else.
I’ve found that some people, for whatever reason, do better on Cytomel and some do better on NDT formulations.
If you spend time on social media or the internet in general, you will find groups of people who advocate and evangelize both.
But don’t fall for the hype either way. One is not inherently better than the other even when you start throwing around terms like “natural” or “synthetic”.
The reality is that both can work and both can help you lose weight. Which one you choose is more a matter of preference, tolerance, and trial and error.
The next thing we need to talk about is side effects.
Side Effects
If you are planning on taking Cytomel then you should be aware of its potential to cause side effects.
These side effects tend to be dose-dependent so whether or not you will see good or bad side effects depends on how much you are taking.
The higher your dose the more likely you are to see weight loss but also the more likely you are to experience hyperthyroid symptoms.
For those who start taking it, here are some common side effects that you may see:
- Hair loss
- Heart palpitations
- Increased heart rate
- Increased body temperature, hot flashes, or warm flushes
- Weight loss (most common) weight gain (uncommon but does happen)
- Jittery sensation or increased anxiety
- Headaches
- Loose stool or diarrhea
Let me be clear in stating that these are the negative side effects that may occur only if you are taking more than you need.
If you are taking the exact amount that your body requires, which is always the goal, you should not experience these negative side effects.
Instead, you should experience these positive ones instead:
- Weight loss
- Increased energy
- Decreased hair loss
- Increased cognition and improved memory
- Decreased brain fog
- Improved sleep
Again, whether you experience positive or negative side effects has everything to do with how much you are taking so make sure to spend time optimizing your dose.
Cytomel is definitely one of my personal favorite thyroid medications because it’s far more powerful than alternatives like levothyroxine.
But this power does come with some added responsibility and it will only work if you dose it correctly.
If you can nail down both of these things, though, it will go a long way to helping you effortlessly lose that extra weight caused by low thyroid function.
By the way, if you are a thyroid patient trying to lose weight, make sure to check out this article next.
It walks you through how to use T2 thyroid hormone which, much like T3, is stronger than T4 when it comes to boosting metabolism and most thyroid patients have no idea that it even exists.

Hi, I have just switch to Naturthroid I was on Synthroid for 10 years. On my last doctor visit all of my labs Free T3, Free T4 were normal my TSH was .31 This was a new provider a functional medicine MD and acupuncturist, she is leaving but will help me get started we talked about Cytomel to add. my question is I think my doseage is wrong I am taking Nature Throid 118mcg and my Synthroid was 137mcg, and should I take it under my tongue? and should I split it and take morning and later afternoon? Thank You for any response.
Hey Rene,
Many factors go into deciding when and how much to take your thyroid medication, I wouldn’t be able to provide you with this kind of information without a detailed history so I would recommend you take those questions to the physician who originally prescribed you the medication.
Hi Dr Childs! I would like to know if collagen helps with thyroid??
Hello,
I had my thyroid removed in 2009. I started with Synthroid…after 2 years it all of a sudden stopped working. Then I went to Tirosint, which was ok. My bloodwork always said it was in the normal range. Then the weight gain started….and kept going. I feel terrible. I kept telling my MD. this can’t possibly be as good as it gets. I would cry, for no reason. He put me on Lexapro. So, 5 years ago I moved to Panama. The only med available is Eutirox. I spoke with an MD here and started on it. I though it would be easier than shipping med in. It works ok…keeps my levels in the range they should be BUT…continued weight gain, fatigue, joint soreness and back pain. I am exhausted all the time. I would like to try adding some T3 and have read your complete article. The thing is, down here, you go to the pharmacy and get it yourself with no RX. I have no idea what to do. Should I start with the 5-10mcg?
Thank you
Hi Dr Childs,
I tried introducing 5mcg of T3 to my Levo but after a few days I experienced terrible insomnia and was forced to stop after 9 days. I experimented with dosing at different times of the day but it made no difference. My Free T3 is low in range. When I took it in the afternoon I experienced afternoon fatigue. I’d really appreciate your advice. Please help.
Thanks
Aysha
My Doctor prescribed Liothyronine (25 mcg). In your opinion, is this too high a dose to start for a borderline low thyroid? I’m really concerned with the hair loss side effects I’ve been reading about. Would starting with a lower does and slowly increasing the mcg over time increase the odds to not experience side effects? I realize you can’t give me personal advice so I’m posing this question anecdotally and of course will consult my physician about my concerns once I understand more.
This is an excellent blog and I appreciate all the information you are sharing.
Hey Michele,
The hair loss associated with cytomel is usually temporary and occurs at any dose.
You can read more about the causes of hair loss due to various issues in hypothyroid patients here: https://www.restartmed.com/thyroid-hair-loss/
Your reading bave helped me so much. I tried to schedule a paid consult but they said you were not taking any more clients. I have hashimotos and recent tests showed hight T3 and high RT3 (23) if I have T3 pooling how much T3 should I take to decrease the RT3 but also help me? I have extreme fatigue, keep getting sick, gained weight. I assumed no T4 until RT3 is lower but I don’t know how to dose the T3 since labs showed this was high too. Also do you recommend any good doctors in the NYC area? Thank you so much!
Hi Tammy,
Unfortunately I don’t have any recommendations of physicians in that area.
Hi Dr Childs, I have had a total thyroidectomy due to cancer. I take NDT which has been lower as my tsh was suppressed. Though i felt fine. Problem is now i have gain weight and have constipation, even though my diet is good.I don’t eat meat or dairy. Doctor is happy with my tsh levels now. Do you have any suggestions.
Thankyou Jennifer
Hi Jennifer,
I would check your free T3 + reverse T3 levels.
A doctor that doses NDT by the TSH and not your levels of Free T3 and Free T4 will keep you hypothyroid, as NDT (or a T3 medication) suppresses TSH. You need to go back to the dose that was working for you! You were not โhyperโ if you had low TSH. Only high frees mean you are hyper.
Hi Amy,
While it is true that those on NDT tend to have a suppressed TSH, it is by no means a requirement when using NDT. It’s quite possible to have a normal TSH while using NDT and feel fine.
In addition, while suppressing the TSH does not automatically mean that you are hyperthyroid, there are certainly people who can become hyperthyroid with a suppressed TSH on pretty much any type of thyroid medication including levothyroxine.
When it comes to thyroid management, it’s best to take an individual approach because each person can and does react differently to thyroid medication. What works for some may not work for others which is why a dogmatic approach to thyroid management doesn’t really work.
I’ve gone thru 5 endocrinologists to date……..NONE will discuss adding T3 to my levothyroxine. I have all but given up. Lost my thyroid due to cancer. I even called the CVS pharmacy and the pharmacist said he doesn’t have hardly anyone who prescribes cytomel…… maybe a couple prescriptions a year??? HOW, do I find someone that will even consider it. Talk about frustrating.
help!
Hi Kim,
It can be difficult to find someone. Generally your best bet is looking outside of the insurance model.
I have tried numerous times to download your free e book.
Nothing is in my inbox. I have also checked junk mail.
I really appreciate it if you can send it to me.

I take 175microg. of levothyroxine with 50mg cytomel daily. I have lost weight finally. I was diagnosed with advanced thyroid cancer and goiter at 30 y/o. After a few years of adjusting my levo dosages, I researched hormone therapies for thyrodectomy patients and discussed my options with my PA. I also pay cash for appointments and medications, which I feel gives me more options and leverage than those using traditional doctors. My biggest health challenge continues to be extreme fatigue.
Hi Kelly,
You might find this article helpful: https://www.restartmed.com/thyroid-fatigue/
This was a wonderful article as I have been exploring recently. I am 50 and was diagnosed with hypothyroidism when I was 26 years old. It runs in my family amongst most of the women. I was on Synthroid only until about 10 years ago when my dr. put me on Cytomel as well. I started with 5 mcg. My Synthroid doses have changed over the year based on lab work.
I am currently on 112 mcg Synthroid and 10 mcg Cytomel. I am feeling all the symptoms again lately: extreme fatigue, brutally dry, weight gain (even though I am a gym rat), etc. I am dry to the point that my skin hurts to be touched sometimes.
Would an increase in just Cytomel likely help? Or would it be an increase in both?
I am definitely going to be bookmarking your site!
I have Hashimoto’s and after starting the Cytomel, I am starting to feel a bit better. My son also has Hashimotos and is morbidly obese. We got the “chubby kid” talk for years and nobody would listen to me about my undiagnosed thyroid issues when pregnant with him. He is only on 112 mcg levothyroxine and has severe symptoms, still. His TSH was 3.79 and T4 was like 0.9 at last lab. His endo did not want to put him on anything different. Is T3 safe for adolescents to take? I am taking him to see an APRN May 5th because I know how they run the clinic I am taking him to and think they listen to patients and are up to date on current evidence and guidelines. What are your thoughts on this? (He is 5’7 and 230 lb at 12 years old- He was a 7 pound full term baby, no complications at delivery, and though he was always pretty tall, he was really thin (10th percentile) until he weaned at 27 months old). Also to note, when he was first diagnosed, his triglycerides were in the 400s, and, though A1c was fine, he has some acanthosis nigricans, so I am worried he is developing T2DM (his younger brother has Type 1). Thoughts?
Is there a range for optimal TSH, FT3. and FT4 on Cytomel only? I’ve read these tests aren’t meaningful when on T3 only. The lab reported my T3 is above normal & T4 was below normal and TSH was normal which I’d expect 3 hours after taking T3. I feel better being off Synthroid.
Hi Gayla,
I have a T3 thyroid titration and dosing guide video in my weight loss program that goes over how to monitor thyroid lab tests while taking T3 medication. You can find more info here: https://www.restartmed.com/hormone-mastery/
Hi ,
I had a near total thyroidectomy in April 2010. I was initially placed on Synthroid 100mg then I was increased to 115 to to 135 to 150 and I’ve been on 175 for almost 2yrs. I workout 3-5 days a week.Im on all natural vitamin supplements by Youngevity &it has helped me tremendously. I eat fairly healthy ect. But Im often tired, lethargic,Moody,no energy ect. I dont know what it feels to be normal. I do have good days but i habe those days i really have to still push myself to say active. I’m 36yrs. I dont think my T4 is Not being converted to the active T3 because I’m gaining weight in spite of exercising ect. I’m 20 lbs heavier than my normal weight .What do I do???

Hi Dr. Childs, how do you feel about Armour Thyroid and when/if do you prescribe it?
Hi Virginia,
Nowadays I don’t prescribe armour thyroid very often, I usually prefer WP thyroid if I’m using NDT.
Hi Dr. Westin Childs,
Thank you very much for writing this article. I have been working to treat a persistent, inexplicable weight gain for about 1.5 years now, and this article was like a glass of water in the desert.
I eat incredibly lean, and exercise regularly, however, had a surgery in November 2015 and ever since then, my weight slowly climbed from 140 to 156 and it won’t budge. I have tried the following:
-Baby dose of cytomel (5 mcg), no results
-Baby dose of Liothyronine, no results
-One grain of Erfa Thyroid (i.e., desiccated), no results
My labs all show the lowest end of normal, however, a new GP agreed to try me on 15 mcg of Cytomel in conjunction with an adrenal support supplement from my naturopath. I started on May 5th; I weighed myself about 10 days later and my weight was the same. To be honest, I was very discouraged. Is this unreasonable? I read that cytomel’s effects are immediate; is this not the case?
Any input would be greatly appreciated – again, thank you so much for taking the time to write this article.
Warm regards,
Natalie
Hi Natalie,
If you’ve already tried cytomel and it didn’t cause weight loss then it’s not likely to cause significant benefits in incrementally smaller doses. T3 is more of an augmentation to weight loss, than a true weight loss therapy itself. You can find more information about layering medications, supplements and therapies for weight loss in my guide here: https://www.restartmed.com/hormone-mastery/
Hi Natalie,
I am having the same issue. I am not on 75mcg and nothing. While everyone is looking thousands of pounds…nothing for me. Lets connect and share what works. Please e-mail me at galinatulman@aol.com
I would like to connect with you.

Loving this article! I am currently self medicating T3 and T4 and used to take 150 T4 but have switched to 125 T4 and 25 T3. Does that sound OK or too much T3?
Hi Emily,
Each person requires a different amount of T3 based on existing resistance, reverse T3, body weight, metabolism, etc. so I can’t really say for sure.
Here is my question: Does a high Reverse T3 level suppress your TSH? I ask this because I have midrange Free T3, normal range Free T4 and total T4 and my TSH is now below .1, but my RT3 is a nasty 34. Also, can allergies be the cause of a high RT3?
No it doesn’t suppress your TSH. Your TSH is likely suppressed because of whatever medication you are taking.
I’ve read reports of generic Cytomel causing acid reflux and heartburn that improved on (expensive) brand name Cytomel. Any reports of this?
I’ve never personally dealt with this, but it wouldn’t surprise me. It’s relatively easy to switch from brand to generic and would be worth the extra money if it didn’t cause reflux in some patients.
Hello,
My doctor put me on Cytomel and I’ve been taking it for 3 weeks. I absolutely have zero rise in pulse or body temperature. I started with 25mcg and now on 75mcg and still nothing. I dont understand how is that possible and why its not increasing my body temps. I’ve noticed that my body temperature went lower actually. Can you explain what would be the reason and what should I do. Its a bit frustrating. Should I increase the dose? Please explain to what do u feel is going on.
Hello Dr. Childs, I have been taking 25mcg of Cytomel alone for about a year now. My most recent lab results show that my T3 is high (5.4) and my T4 is low (.23). Do these results indicate too high of a dosage of Cytomel, or possibly, too low of a dosage? I feel fine with exception of increased hair loss recently. Thank you very much.
Hi Kileen,
There’s much more to interpreting your lab results when taking T3 including other factors such as sex hormone binding globulin, total T3, body temperature and resting heart rate. I discuss how to interpret lab results when taking T3 in my weight loss guide.
How come you answered Kileen question but skipped mine and didnt answer me? Thats strange. I asked a question few days before Kileen
I have 3 years of labs with 2 different meds and unmedicated.
My current situation is I have heart palpitations, sweating 24/7, weight gain, headaches, foggy. Was just raised from 25 two weeks ago to 37.5 Levoxy t4, 5 Liothy twice a day, 200 mg Selenium, Vit C, Turmeric, Probiotics refrigerated 5b sacchromyces boulardi and Bio MOS, 10b acidophilus Bifidus, vit D, occasionally Lysine. I weigh 185, 5’6″, late stage Lyme for 5 years treated with antibiotics, wormwood, licorice, Black walnut. Adrenal adenoma 14mm. 9mm nodule on liver benign appearance, Cyst ovary 2.2cm, uterine thickness being monitored. Healthy everywhere else. My resting heart rate 75, temp and blood pressure normal for last 5 or so years before that 96 was my healthy temp since I was a teen with blood pressure consistently 90/60 with good energy and I’m almost 50 now.
2017 25-t4,10-t3: 1.11 TSH, Total t3 98, 0.7 Free t4
2016 Unmedicated: 5.98 TSH, 2.9 Free t3, 0.9 Free t4
2013 2gr Armour : 0.03 TSH, 6.3 Free t3, 1.0 Free t4, 13 Reverse t3
I felt great with the 2013 dose when labs were done, lost patches of eyelashes though. 3 months later I gained 5lbs was sluggish depressed.
After reading about too much t4 and I had recent reaction to raising it I dropped Levoxy to 12.5 today and want to raise Liothy from 2-5mcgs a day to 3 since I crash at 4 ish every day and wake up at bedtime. I have permission from my Doctor to change the meds. What are your thoughts on my history and current situation please?
Hi Dr. Childs,
Your website is the only one that made sense and provided all the information about hypothyroidism/hashimoto for me. I’ve been on levothyroxine for 10 years now. I’m 36yrs old. I started off at 25mcg Levo and it went up 25mcg with 2 pregnancies so I was at 75mcg. The doc said I was fine to stay at 75mcg since my labs looked fine. Recently, o started bloating, frequent urination, gaining weight, hair loss, depression..etc. I workout 5 days/week and ea clean. I’ve always been heathy. I knew something was wrong with my thyroid so I went to my physician and asked them to do a test- he only checked tsh and t4, and later after reading your site – I asked for full panel thyroid test and found out I had Hashimoto. I’ve been on gluten, dairy and soy free. Also, had more rt3 and t4. So I asked to be on cytomel. He put me on 5mcg and lowered my Levo to 50mcg. I felt awesome after taking cytomel-energetic, losing weight, positive,but been on for 3 weeks and now I’m feeling the same bloating, depression and fatigue. Do you think I need to up my cytomel to 10mcg? Also, I also think it’s adrenal issues. I was planning to take Ashwagandha. I already take zinc,selenium and multivitamin. Please advice if the symptoms could be a sign that I need to up my cytomel?
Hi Dr. Childs,
I’m 41 and have been on levoxyl for nearly 10 years. I was first diagnosed when trying to get pregnant. TSH was around 3.5 so not super high but they wanted it around 1 for pregnancy. I’m on 50mcg but I just switched endo’s and he noted that my free T3 was still low at 2.6 despite my TSh being 1.8. I’m not overweight (5’2″ 119 lbs) but I do feel “puffy” for me (weight was around 108 before starting levoxyl 10 years ago)and cannot shed a pound despite clean eating and running 20 miles/week. Do you think cytomel might be right for me? Oh and temp is super low…96.8 -97.2. Thank you!
Thanks for your article. Can you please recommend a doctor in Vancouver, Canada that understands this? I need help,thanks
Hi Mel,
You’re welcome, but unfortunately I don’t know anyone in that area to refer you to.
Hello dr westchild.
I have a question about the ft3 ratio?
My reverse t3 is low o.33 0.22_0.54.
So I think my rt3 is good but my ft3 is 4 3.1_6.8 so my ratio is not good 12.7.
Do I have a rt3 problem because of the ratio. Can you tell more about this? Or not because the rt3 is normal?
Hi there,
I had a total thyroidectomy four years ago.
I am 5″10 and 160 pounds and always have been. I was on an extremely high dose of sybthroid to keep my tsh suppressed. I am now on a more normal dose.
My t3 was low with a high dose and it is low with this normal dose. I show zero hypothyroid symptoms besides being tired. All of my blood and cortisol tests are perfect. My t3 ratio is off. It is just below the normal range. Any idea why?
That being said I am going to add .5mcg of cytomel to my 125 mcg of sybthroid a day.
Last time I tried this I puked for five days straight. I quit after that and want to try it again. I do not want my heart rate to raise. It is resting in the 50s currently. Any advice if this is a good idea? I take 125 mcgs synthroid 9 times a week and will add. 5mcg of cytomel. Let me know your thoughts.
Hello ๐
Thank you for taking the time to read and help everyone, it’s so generous and life changing… I’m currently on 100mcg synthroid with 25mcg cytomel (1/2 in the am 1/2 afternoon)… I also have adrenal fatigue and I’m taking adaptogens plus adrenal cortex.. it seems in getting hyper..I feel Palps and I’m shaky dizzy foggyv etc. .. I’m wondering what the next dose down would be? I have to be very specific with my doc for dosing… as he prefers to just scribe synthroid…
What dose do you suggest a person with high reverse T3 take of Cytomel (liothyronine)? Here are my 2017 and 2015 thyroid test results (With Free T4 & Reverse T3):

I need you advice on what you think is going on here. What you believe my situation is since you seem to be very knowledgable and the doctors may not always have a clear of what is going on. I was treated for mental illness and bi-polar disorder and and accidentally overdosed on psychiatric medications when the doctor handed me a hand written note instructing me to take 8mg of a psychiatric medication, when the highest dose anyone was supposed to take was 3mg. Anything over 3mg was an overdose amount. I do not know why he told me to take 8mg. Medical negligence I guess. Sick of doctors, sick of being misdiagnosed. I have been having nerve pain, heart palpitations & pain, joint pain, back pain,(vertebrates crack a lot and shift, I was in 3 car accidents and was diagnosed with slipped discs), insomnia, low libido, small nerve twitching in arms and legs after sex, dry skin, memory issues, brain fog, itching.
I would like to get all of these symptoms resolved once and for all. I have been living with them for quite some time I think(I got so used to it, I didn't realize anything was wrong, I think it just became normal, I have a high pain tolerance, might be why). I need to know from someone who knows what they are talking about what dose of cytomel is recommended so I know what dose to ask for when I see a doctor. Do you have any advice or recommendations for me after looking at my test results?
Hi
does cytomel have a short half life? if I were to experience palpitations due to cytomel how soon after taking my dose would that be
like if i took cytomel at 7am..the racing heart I experience at 6pm will be due to cytomel or will it have already left my body? I hope I am making sense..
Kind Regards and Thank You for this post
I persuaded my GP to subscribe T3 (liothyronine 5mcg.) 2 two months later my tsh went from 1.21 to .35
She told me to cut the dosage in half.
I had a TT one yr ago and am currently taking 125mcg Levothyroxine.
Does the T3 lower tsh?
Hi Laura,
Yes, all forms of thyroid hormone replacement will lower TSH. T3 happens to be about 3x more potent than T4 at lowering the TSH.
What are your thoughts on taking cytomel, synthroid, iron and hormone replacement? Is it best to separate all these with a 4 hour window? I’m tending to get up at 5:00 am just to take the cytomel. I feel like drugs run my life schedule.
Hashimotos
I’m currently on 10 mcg of cytomel .075mg synthriod in the morning then 5 mcg of cytomel at lunch
I’ve recently lowered my T4 after reading your blog I have halfed it and thought I should possibly quarter it? I’m still feeling tired and weighty.
I go to a functional doc and was told my thyroid was under active. I was given the smallest dose possible of naturethroid and after a week had hyper symptoms… Racing heart, etc. Would I probably not be able to tolerate T3 either? It’s so frustrating!
Hi! 2012 DX: non Hodgkins lymphoma, had Chemo treatment then developed thyroiditis! Was on low dose of levothroxin for 5 years! Last 2 years developed all the symptoms of hypothyroid with 40 lb weight gain past 2 years, along with cold sweats, extreme fatigue, brain fog, leg cramps! Cold sensitivity ect! Dr checked my tsh level is was 78.9. Rechecked after 6 weeks of 37.5 of levothyroxin. Tsh down to only 64. Saw internal medicine he checked t3 and 4. Said both were low. T3 was 40. I’m now on levo at 75 mcg and started me on liothyronine at 5 mcg! I have been in remission for past 5 years. Took Ritoxin IV for 2 years after done with Chemo last dose of Rituxin was 2 years ago. My question is. Have you ever known a tsh to go that high?
,
Hi Debi,
Yes, I’ve seen TSH levels that high in other patients.
On Cytomel only, Free T4, is very low. Do I need to add T4? I’m having terrible muscle cramps and spasms around rib cage and across shoulders.
Hi Gayla,
Free T4 will always drop if you are on cytomel, determining if you need to add T4 as well can be tricky but you can find out more here: https://www.restartmed.com/free-t4-normal-range/
Hi Dr.Childs,
What are the side effects of stopping levothyroxine and taking Cytomel for a short period of time for weight loss?
Hi Terry,
That would depend on a number of factors and would depend on the individual but not something that I would regularly recommend anyone do (especially now without physician oversight).
I am on levothyroxine 0.2 mcg for the past 20 years. Back in 2001 I went on the depo-provera shot for a year. I noticed I started gaining weight. I stopped the depo and have never been able to get the weight off.
I had my blood work done
My TSH is 0.03 mlU/L
FREE T4 is 21 pmol/L
FREE T4 is 4.3 pmol/L
FSH is 23.6 IU/L
RT3 is 23 ng/DL
My dr started me on cytomel 5 mcg the first few days I felt good then I started getting tired ,ankles swelling so he uped me to 10 mcg. Then to 25mcg.
After taking the 25mcg I started having breathing problems ,headaches ,on edge, sleepy ankles swelling ,brain fog and sweats weakness. My basal temp before cytomel was 95.7 after medication 97.7.
Even when I’m sweating profusely my internal temp is 96.7 at times .
Because of my symptoms he told me to stop the t3 until I get my strength back up.
What I want to know is how do I find out my adrenals are working . I just want to feel better , I’m 47 and feel like I’m 90. I have no energy I just want to sleep.
Do you have any suggestions to help me get my life back.
I would love to hear your opinion if there’s any help for me . Thanks
Hi Wendy,
You can test your serum cortisol and then look further if necessary by evaluating your urinary/salivary levels. You can read more about that here: https://www.restartmed.com/cortisol-test/
There’s always hope, it will just take the right approach to get things back in order. Your situation may also be complicated by peri-menopause/menopausal changes to your sex hormones just given your age.
Hi I started taking cytomel last September 30, 2017 2 50 mcg a day so that’s one in the morning and one in the evening. I’ve noticed that the effect on me is that my hands were shaking and on my 3rd day nothing has been changing or in short i don’t see results. So i asked the pharmacist who sold me the drug, why isn’t the product working on me. He also said that i don’t need to go on a diet and i can eat whatever i want incase i crave. But still im on a healthy lifestyle so every morning i run and watch over what i eat and still i don’t drop off my weight still at 59-60 kg. So last tuesday October 3, 2017 he told me to increase my dosage on 4 50 mcg a day so 2 in the morning and 2 on the evening and still it’s already sunday October 8, 2017 and nothing is happening. I don’t see any results at all which i really feel bad because i need to shape up right away for this position that i am applying for. I seek your help on what to do and how is the proper intake of cytomel. The only positive results i see is that my sleeping condition is okay and i have more energy but weight loss doesn’t show any results. Or would this take time to clense and fix my metabolism? I hope you can help me. Thank you!
Hi Paris,
Cytomel isn’t a weight loss medication in the sense that it will directly cause weight loss. It will only help with weight loss if you have hypothyroidism, meaning your thyroid was low to begin with. If you take excessively high doses of cytomel but your thyroid is fine then it really won’t help with weight loss. I discuss how to use cytomel and, more importantly, how to combine it with other therapies to help with weight loss in my guide: https://www.restartmed.com/hormone-mastery/
Thank you for answering and i’ve seen the link that you pinned in this comment section. So by chance when you said my thyroid is fine so I don’t need to take cytomel? Or is it fine if i take it for weight loss? Can you also advise me how to use it properly with how many amount of tablets i should take a day. Thank you so much!
I have forced my dr to remove me from synthyroid because i couldn’t function on it at all gained tons of weight almost went bald and could never stay awake. I have tried a few natural ones. Armour i didn’t do well on at all. Then i was kinda okay on nature thyroid but it went on national back order. So now i’m on NP thyroid and having a hard time adjusting. The pain, fatigue, joint and muscle pain is really bad and the insomnia is horrible. and at the last appt this week found where i had been stable with weight I have recently gained 10 lbs in the last few weeks. I feel I could benefit from this on a low dose. I find resistance from specialists because they don’t even want me on NDT. How do i get them to try and add cytomel to my day? this last dr only wanted to test my TSH and I made him put in t4and T3 and he argued with me on rt3. but thats all they test me for each time. I need help. I want to feel normal again or as close as possible.
Hi Dr. Childs, my tsh has been taken 5 times in the last few years, usually around 1.5-3. Having pcos and insulin resistance, I had a lot of problems losing weight. Taking phentermine with low titrating doses of topirmate was the only way I could lose the weight, the lowest my tsh has been has been while being on those meds and losing weight (1.5 tsh), after stopping those meds I was able to keep my weight the same around 145 for a few months while I tried to get pregnant, my tsh was about 1.5, t3 140-152, t4 7.6-10, free t3 2.94-3.1, free t4 1.08, reverse t3 20.3-30.3, insulin 5.5-8 (on metaformin), sex hormone binding globulin 80.9, cortisol 31, tpo 11, drvvt 33, vitamin d 30. Anyway, right after they did my first frozen embryo transfer, they took another tsh (right after implantation about 5 days later I think and my tsh went from 1.5 to 3.66, which my RE promptly put me on synthroid 50mcg. I miscarried a few days later. I stayed on the synthroid as we are going to do another FET this month, the first tsh level at baseline before any estrogen was added was .89. My hair last month was falling out at an alarming rate (when it spiked to the 3.66), it has slowed since the synthroid or maybe just because of the miscarriage, but it still falling out every time I run my fingers through it. And I have gained 10 pounds in just a couple weeks after starting it. Do you think because of my reverse t3 being elevated and having pcos and being on metaformin I should ask to start on 5mcg of cytomel with the synthroid? I can’t help but think that it may have made my tsh come down, but with the sudden weight gain so quickly, maybe I am more prone to making reverse t3 than t3. I’ll have to get another set of labs to be sure. Any input would be greatly appreciated.
Hello. Thank you for providing this information on your site!
My TDEE, based on meticulous food/activity logging (weighing/measuring food eaten daily for years) is typically around 60% of what it should be according to various methods of prediction. I am currently exclusively breastfeeding my baby, but I have seen no weight loss despite eating the same amount of calories on average as I did prepregnancy; it appears my body simply downregulates.
My temperature hits lows of 96.3 on any cool day (below 70 degrees), and is generally around 97 on the warmest days. This is with taking 1.5 grains of Nature-throid daily. I find I cannot increase above this level without having episodes of tachycardia (113 resting) and/or hypertension (blood pressure rises above normal levels for a few hours, usually resulting in a migraine).
I’ve had issues with low body temperature & very slow metabolism my whole life, though I am doing much better now than around 10 years ago, when I was gaining weight on anything over 800-1000 calories per day intake.
I have Type II diabetes, but I am currently controlling my blood glucose levels with diet/exercise; I controlled them during pregnancy & before with the addition of Metformin, which I started in 2015 due to an increase in fasting glucose levels despite postprandials continuing to be normal. I am typically around 5.5 A1c, but I have not had my fasting insulin tested.
I am thinking I would do better on T3 only medication. I tried Synthroid and it was like taking nothing; I was literally bedridden on it.
Do you know of any contraindications for taking Cytomel while breastfeeding? I would appreciate any feedback on my situation. I am having great difficulty losing weight. I averaged 9 pounds a year weight loss since 2009 (started NDT in 2013), but this requires doing a minimum of 90 minutes per day on my arc trainer & having an average calorie deficit of 1000+ daily (that is with the adjusted lower metabolism).
I still have around 70 pounds to go. I love exercise, but I just don’t have the time to do more. Eating less never leads to weight loss for me.
Thank you!
My thyroid/related medical history history is complex but here are highlights. I am the only non obese member of a family with a history of both obesity and a hereditary lipid disorder (familial hyperlipoproteinemia dxed 20 yrs ago by head of Johns Hopkins Lipid Cllinic). I am also the only immediate family member not taking statins (even though my lipids are slightly elevated – I refused) and without rhabdomyalysis. One brother is even developing kidney problems (from which our father died).
I’ve been taking Synthroid since I was 25 when testing at the student health center revealed very very low thyroid levels (they didn’t want to test me because I was controlling my symptoms “to the naked eye” – moisterizers, extreme dieting which minimized my sudden weight gain to “only ” 20 lbs., etc. In fact when my thyroid results came back so low, they had me retested – certain it was a lab error)
For years I took Synthroid 2 mg /daily periodically tested for Hashimoto’s (negatiive) which was gradually reduced to 125 mcg. I only take the brand because I believe the dosage is more reliable. Suffering from depression, much slowed metabolism, extreme cold sensitivity, and hypersomnia (average 12 hrs sleep/night – or more) I decided to request T3 supplementaion a year ago.
I am presently taking 112mcg Synthroid (before adding T3 125 mcg) and 10 mg Cytomel, simultaneous.
Here are my present concerns:
First, I improved dramatically with T3 – morale improved, sleep down to ~ 8 hrs/night (MOSTLY! Confused by varariability), less cold intolerance (Raynaud’s still a problem) and higher energy level (though not where I’d like it). My appetite increased a great deal too, though, causing weight gain ( ๐ )but I think/hope it’s due to a relapse of my “carbophilia” which I’m now struggling to control with slow success. (I know I messed up my insulin metabolism – has happened before.)
Note: I am 71.
Second, I have slight Atrial Fibrilllation (need cardiac work up to confirm) – on medical todo list is Holter Monitor test. In any case, I want to be careful with T3 on this account.
Three (and this is the main area of confusion), I’m taking pains to separate the following medicines by several hours because I was told they “compete for absorption”: estradiol and progesterone (OKed for extradordinary reasons via cost/benefit analysis), iron (I’ve had anemia dating from same testing period when hypothyroid was identified; i.e., age 25), and calcium to help main marginal bone density . Actually, I hardly ever get to the calcium because the med timing is already so complicated to keep on top of (horrible enough to try to take both thyroid hormones first thing in the day, least of all, before any food comsumption. There’s a limit to how much I can live my life around scheduling medicines much less managing other medical issues! E.g., had T4-pelvis spinal fusion last year, breast cancer the year before – now OK after surgery) and a few oddds and ends.
However, a mainstay of your recommendations to regulate T3 is to divide the dose or take it in slow release form.
HOW AM I SUPPOSED TO MANAGE THIS? Surely, I’m not the only woman taking these meds!
Help!
PS I live in a “medically underserved ” area – at present no endocrinologist and only one ENT. Travelling to nearest acceptable medical center is bankrupting me financially in $ and time.
Pt II
Many apologies for multiple typos! Hope you can decipher previous message.
Decided to add, that I have high consumption of dairy products so am not worried about often missing calcium dose.
Also, I have not been tested for โreverse T3โ or Leptin resistance but hope I can persuade endocrinology PA to order them (sheโs been taking over for former endocrinology who is on indefinite medical leave. Donโt know how much discretion she has though (adjusting the Cytomel has been very complicated, involving lab errors and a few โmysteriesโ)
Lastly, I have decided to request ENSAM (selegeline patch) to treat my depression. I have high hopes despite long history of TRD (Treatment Resistant Depression) as one MAO-inhibitor depression (NARDIL) worked brilliant though no other AD did. Unfortunately, a common side effect – extreme orthostatic hypotension landed me in hospital for long stay so had to discinue.
Hopefully, though less effective, the ENSAM will help and since itโs delivered in a patch, it will not require the same dietary restrictions (note, my problem was HYPO-tension, NOT hypertension – the infamous tryamine reaction.)
HOWEVER, how might it interact with the thyroid, T3 especially?
Many thanks for your extremely educational page! Endocrinology certainly requires a Sherlock Holmes!
Morning
Thank you for all your detailed information.
I am in the UK and have been using t3 for hashimotos for the last 3 years. I have a question…..is it impossible for t3 to convert to rt3?
When I started t3, I lost about 14lbs with no effort at all, no dieting the weight just fell off, then with no change to dose or diet after about 8 weeks the weight went back on. I feel better on t3 so have stuck with it but cannot shift the weight I take 25mcg of cytomel 3 x a day.
My body temperature is still quite low around 36 degrees.
Would be very interested in your opinion.
Regards and thanks
Kim
Hello , your site is wonderful . Iโve studied most everything Iโve read from you prior to seeing yours . But Iโm still stuck at this weight . Canโt budge a pound. I noticed the weight gain after I switched from armor to Synthroid . Not my choice . My insurance stopped due to a divorce . I then had spine surgery adding to my weight from the steroids . I havenโt taken them in 8 months and Iโm not on any pain lkillers either . I hated those !
I felt the synthroid was not doing anything . I started t3 only been a week but no weight loss yet . Is it to soon ? I do feel 100 % better on it ! I can think clear ! I sleep better than I have in years! Real sleep ! I see positive results just no weight loss . Should I up it you think? I take 25 mg . Iโm 5โ9 220 . Which is insane ! Iโve alwats been 170 ! I canโt stand myself ! Iโve used progesterone cream too . To balance estrogen dom. Iโve used DIM also . I hardly eat anything ! I never drink soda ! I eat organic . I never drink milk . I donโt eat fried foods . I watch what I eat !i should be so thin . I even work out . Whatโs going on . I detox a lot . I take zinc and minerals too . I tried ox bile and other herbs . Amino acids . Nothings working . My sex drive is killer! But it always was lol Iโm 51 years old . Help !
Why is everything marked up to the point only the the rich can afford it. I’m on SSI and that’s way out of my reach. I would love to try this I’ve put on 35 lbs in 4 months and am in pain most of the time. I’ve been to 3 different Doctors for pain and and even a Thyroid Doc and still no help.
Goo day Dr. Westin Childs!
I am also an MD, and I am currently studying for my licensure examination. I am quite well-informed as to effects of T3 in the body, both its desired effects and some adverse effects. And reading your article here added up to the knowledge that I already have, so thank you for that.
I am a 29-year old Asian male; height of 183 cm, weight of approximately 220 lbs (110 kg), with a sedentary to light activity lifestyle. My diet includes lots of carbohydrates in it, considering that the South East Asian diet comprises of lots of carbohydrates in it. Although I try to cut down on my CHO intake; given my age, it is truly difficult to loose weight just by adjusting and modifying my diet alone. I also had MD friends before who took some pills during our med school. They claimed to have had increased focus and insomnia (they were able to study for longer periods of time), palpitations, and tachycardia. I therefore suspected that the pills they were taking had some thyroid hormone in it.
I know that it is not advisable to take thyroid hormone, in this case Liothyronine (Cytomel), because of the possible harmful effects, especially I do not have hypothyroidism. But some of its side effects like increased focus and insomia might help me in studying for the licensure exam since it is imperative for me to do a lot of reading, and I may also benefit from its weight-losing effect. Perhaps I will only be using it for around 4 to 5 months. I am planning to start on the lowest dose, then monitor my vitals as what you recommended, and titrate Cytomel carefully depending on my symptoms (if ever I develop one). I plan to do a one-week daily monitoring for a baseline of my vitals prior to starting Cytomel. What do you think of this, Dr. Childs?
Hi Dr, Child’s,
I have high reverse t3 due to prolonged stress. I am having hypo symptoms and under the care of a functional med doctor. She wanted to start me on NP thyroid but I shared that the T4 in the rx may create more reverse t3. I have never been on thyroid mess because my thyroid has always been in the normal range. My stress has substantially reduced. I asked her to consider a t3 only med and she said she would prescribe liothyronine. Is there any chance my reverse t3 can go away without medication? Thanks for all your work and knowledge on this topic.
When is T3-only medication appropriate? My issue is definitely one of conversion: my TSH and T4 are both in the normal range, but my T3 is low and my reverse T3 is definitely high.
I don’t understand why I would then take a combo of more T4 and some T3 instead of taking just T3. I have taken Armour in the past with zero benefits and my blood work just showed the same old “low T3” and high reverse T3 after several months on Armour.
Also, if I do start on T3 only–not sustained–how many hours as I supposed to wait before I take a second dosage? (I’m talking about only 5 mcgs at a time.)
Finally, can T3-only meds be taken in the evening or are they likely to keep you up?
Thanks so much for the wealth of information!
Hello, Very useful site, thank you. I’m a 51 year old active, healthy woman. After years of trying to lose weight thru diet and exercise, a nutritionist said she thought I wasn’t eating enough and sent me to get a Metabolic test. It showed I needed only 800 calories a day to function, 25% less than the average woman my age. My GP said I could talk to Endocrinologist who put me on 5mg of Cytomel in addition to the 125 of Synthroid I have taken since I was 15. I lost a pound a week for 8 weeks, but now it’s started going back up. Endo doc said new labs were ideal, but I’m thinking of increasing to a second Cytomel per day, 6 hours or so after my morning Cytomel because I have very bad insomnia.
I am so tired of the self-loathing of being overweight despite my best efforts. Any suggestions would be helpful. My HMO seems to be based on me leading the way thru inquiry and research.
Thanks very much!
Hi Marcy,
What you are experiencing is not uncommon among many people who are overweight. I’ve discussed this phenomenon in detail here: https://www.restartmed.com/symptoms-of-not-eating-enough-calories/
You can also learn more about my personal approach to weight loss here: https://www.restartmed.com/hormone-mastery/
Dr. Childs,
After years on Levothyroxine, my doctor just prescribed the combo including liothronine. I was on 150 MGC of levothyroxine. He now prescribed 100 MCG of levothyroxine with 5 MCG of Liothyronine. That seems like a large decrease of the levothyroxine. Is that the right ratio when I was originally on 150?
Hi Tiffany,
There isn’t a set “established” guidelines for conversion but a helpful place to start is to consider that T3 is approximately 3-4x more potent than T4.
What about those of us who had their thyroud removed due to thyroid cancer or other issues…?
I’m now tagged with fibromyalgia, arthritis, chronic fatigue, (anxiety, ptsd, dealt with that most my adult life but, it’s heightened since my total thyroidectomy). I had to fight hard for t3 meds. Currently 100 mcg tirosibt, 30 mcg cytomel a day. I notice a huge difference. It took me close to 2 years to get to that dose- doc playing god or fear of medical malpractice because my tsh numbers (suppressed due to thyca)..
I’d like to do more t3 therapy and cut farther back on my t4.
So….
For a person with no thyroid, will we produce enough t4 if we are on higher doses of t3 and lower t4?
I’d love more info for us with no thyroid.
