Treat the root cause: your gut
Stop letting thyroid bloat, fatigue, and brain fog run your life
When your thyroid slows down, it takes your gut along with it. That means uncomfortable bloating, fluid retention, and that heavy “weighed down” feeling that lasts for hours.
Most probiotics are made for everyone. I designed Thyro Biotic specifically for you. It’s the only probiotic formula crafted for thyroid patients to support thyroid hormone conversion (T3) in the gut while calming the inflammation that leads to cramps, gas, and bloat.*[1]
Dr. Westin ChildsThyroid specialist and formulator
Your thyroid slows your gut
A sluggish thyroid means a sluggish gut with symptoms like bloating, constipation, and even extra waste weight.[1]
Bad bacteria overgrow & thyroid function suffers
Food that sits in your gut changes the balance of healthy to unhealthy bacteria. It also impacts your body’s ability to create T3.
The right probiotics help bring balance back
Lacto, bifido, soil based organisms, and beneficial yeast, provide long-term and short-term benefits to your gut.[4][5]*
The gut-thyroid connection
What a healthy gut does for your thyroid
Your gut and your thyroid are in constant conversation, which is why gut support looks different for thyroid patients.[1]
Benefits of supporting your gut as a thyroid patient include:
- Support for T4 to T3 conversion: roughly 20% of thyroid hormone conversion happens in your gut[1]
- Support for thyroid medication absorption and efficiency
- Support for T3 recycling in the gut
- Immune system support, since a large part of your immune system lives in and around the gut
So while you’re supporting your digestion, you’re also supporting the system your thyroid depends on.*
What’s inside
Research-backed ingredients
Soil-based organisms Bacillus clausii, coagulans & subtilis, 24.96 billion CFU
SBOs are some of the hardiest bacteria we know of. They can withstand harsh environments in the body, which means they don’t die off when introduced to stomach acid. They reach your gut alive and colonize.
Bifido & Lactobacillus strains 9 strains, 31.2 billion CFU
Well researched and well tolerated, these strains act by influencing the growth of bacterial species in the gut. This is the fast-acting layer of the formula.[4][5]
- Lactobacillus acidophilus
- Bifidobacterium bifidum
- Lactobacillus casei
- Streptococcus thermophilus
- Lactobacillus salivarius
- Bifidobacterium lactis/longum
- Lactobacillus plantarum
- Lactobacillus rhamnosus
- Lactobacillus brevis
Saccharomyces boulardii beneficial yeast, 4.16 billion CFU
This beneficial yeast helps support the immune system by supporting the production of immunoglobulins, and crowds out the organisms you don’t want in your gut.[2][6]
Prebiotics FOS, fructooligosaccharides
Prebiotics are included to help the probiotic species thrive and make it to their destination.
Not another probiotic that dies in your stomach
Most probiotics die in stomach acid long before they reach your gut. The species in this formula don’t.
2 capsules per serving
Recommended dose: 1 serving (2 capsules) per day. One bottle lasts 30 days.
No refrigeration needed
The strains are shelf-stable, so they keep their potency at room temperature.
60.32 billion CFU per serving
13 different species with enough combined CFUs to actually change the balance of bacteria in your gut.
Real-world patient outcomes
What thyroid patients actually report
Pulled from verified reviews and the published Patient Outcomes Report for this formula, not from a study we paid for.
“I’ve been taking Thyro Biotic for a few years. It has vastly improved my gut health which in turn helps other bodily functions that I can not visibly see. I have zero constipation now and my system is like clockwork. If I miss a couple days of Thyro, I suffer the consequences. I have a healthy immune system as well. Love it!”
Acid reflux disappeared
I’ve been using Thyro Biotic for a few months and my acid reflux disappeared. Also, my nausea from eating food improved.
Normal, healthy bowel movements again
This product has really made a difference to my health. I have struggled with loose bowels for over a year and I am so happy to be having normal, healthy bowel movements again. I’m really grateful I tried this.
Eliminated the daily gas
I was using another brand of probiotic which gave me quite a bit of gas. This Thyro Biotic has eliminated the daily gas and has eased digestion issues. I will definitely keep using this product!
The first probiotic to make a difference
This is the first probiotic to make a noticeable difference and I never want to be without it.
Better balance within a week
After researching the gut-thyroid connection, I decided to try Thyro Biotic for its targeted formulation. I experienced mild initial adjustment as my microbiome adapted, followed by noticeable improvement in balance and overall well-being within a week.
Tried plenty, this one stands out
I’ve tried plenty of probiotics over the years but this one stands out as the BEST! No gas or bloating.

Frequently Asked Questions
The recommended dose is 2 capsules per day, taken with or without food, and at least 30-60 minutes away from thyroid medication (if you take any).
2 capsules will yield about 60 billion total CFU of probiotics.
Probiotics are generally very well tolerated but some people may notice some changes in bowel function when they first start using them.
These changes may include symptoms like changes in bowel function, initial bloating, a temporary increase in gas production, the sensation of your stomach churning, and changes in the color of your stool.
These symptoms do not always occur and, when they do, typically resolve within about a week or so of daily and consistent use.
They stem from the changes that occur to your microbiome as your body adjusts and adapts to the introduction of new species.
Most people who take Thyro Biotic will not experience any negative symptoms but, instead, will see a positive improvement in their overall gut health.
Each person will experience different benefits when taking a probiotic because no two people are alike, especially when it comes to gut health.
Most people will have a pretty good idea if it’s working because they will notice an improvement in their gut-related symptoms.
This could be something like a reduction in gas, a reduction in bloating, normalization of bowel movements, better mood, clearer skin, clearer thinking, or a general sense of wellness.
It’s hard to predict or pinpoint how any one person will react to probiotics because they have such a broad range of benefits.
The benefits you see will also depend on why you are taking it.
For instance, if you are taking it for general health and gut maintenance then you probably won’t experience any significant benefit because there wasn’t anything wrong, to begin with.
In this setting, you are just insuring that your gut will remain healthy through the ups and downs of life.
If, on the other hand, you are dealing with all sorts of intestinal problems then you should notice changes to your general bowel health, bowel movements, and bowel function.
When determining how Thyro Biotic is helping you, make sure you take into account the length of therapy.
Your gut health is not something that will turn around overnight but is something that will require consistent and daily care to improve.
Some people do notice an almost immediate improvement when taking probiotics but it can take up to 90 days to see a difference for others.
Possibly!
Thyro Biotic is not a weight loss supplement, but it is well known that improving gut health may allow for easier weight loss.
Having said that, I wouldn’t recommend using Thyro Biotic solely for weight loss but instead as part of a comprehensive thyroid wellness program designed to improve your overall health and thyroid function.
When you use it in this setting it is very possible that you will lose weight and feel better but it would be hard to contribute that weight loss directly to the use of Thyro Biotic.
If you plan to use Thyro Biotic as part of a comprehensive weight loss program then here are a few tips:
- Make sure you are eating a healthy whole-food diet, fasting consistently, and exercising regularly.
- Take 4 capsules per day of Thyro Biotic instead of the recommended 2. Higher doses of probiotics tend to work better for weight loss.
- Combine Thyro Biotic with my other weight loss supporting supplements like Berberine 500+, Essential T2, Leptin Resistance Rx, GlucoSlow Fiber, and Thyro Fuel.
- Make sure you are also optimizing other hormones like insulin, leptin, thyroid hormone, and cortisol.
- Consider using my 60-day weight loss guide which is included in my weight loss supplement bundle.
No! Thyro Biotic is considered heat stable which means it doesn’t require refrigeration.
With any probiotic, there will be degradation of certain species over time.
The soil-based organisms and the beneficial yeast are more hardy compared to the bifido-lacto strains, but neither of them requires refrigeration.
It is best to store the probiotics in a cool place, however, which will slow down the degradation of the various species over time.
No therapy (aside from thyroid medication in some cases) is technically required if you have hypothyroidism or Hashimoto’s but it would be a very good idea to consider using probiotics if you have either condition.
Few thyroid-supporting therapies have the potential to help in so many different ways as probiotics which makes them a no-brainer for anyone with thyroid disease.
Some of these potential benefits include enhancing the effectiveness o your thyroid medication by increasing absorption, helping increase how much T3 your body produces from T4 to T3 conversion, and enhancing the nutrients you absorb from food that your thyroid needs to function.
These benefits in combination with their potential to help resolve gut-related symptoms like gas, bloating, constipation, diarrhea, and abdominal pain makes them an ideal supplement for anyone with thyroid-related problems.
Absolutely!
Thyro Biotic is considered a thyroid-supporting probiotic but it will not make your thyroid function worse if you have Graves’ disease or hyperthyroidism.
Probiotics will have a balancing effect on systems in your body which will act to normalize your physiology.
This means if you are hyperthyroid, normalizing your physiology will seek to bring your thyroid function down.
And if you are hypothyroid, normalizing your physiology will seek to bring your thyroid function up.
Yes, you can use Thyro Biotic if you have SIBO. While some probiotics can make SIBO symptoms worse, Thyro Biotic does not contain those species.
It contains species like soil based organisms and beneficial yeast that actually help support gut balance in SIBO and SIFO.
Yes!
Like all of my supplements which have been designed specifically for thyroid patients, it can be used with thyroid medication as well as thyroid-supporting supplements.
Like any supplement, though, you would not want to take Thyro Biotic at the exact same time as your thyroid medication.
It’s best to separate the two by at least 30-60 minutes.
When it comes to thyroid-supporting supplements, they can be taken at the same time or away, depending on what works best for your schedule.
Each person is different so it’s very hard to predict what or how soon any one person will see changes.
When it comes to supporting your thyroid or gut with Thyro Biotic, you should plan to use it consistently for 90 days before determining if it’s working.
Having said that, there will be some people who see an improvement in their symptoms after their first dose.
This is not common, but it can happen.
Others will need to use it consistently for 90 days to see changes.
Yes, Thyro Biotic will be replacing my previous probiotics Ultra Biotic x100 and Gut Bomb 350 Billion for the time being.
This new probiotic has been formulated for the unique needs of thyroid patients whereas those previous probiotics were formulated for more general use.
At this time, I am moving all of my supplements over to be more thyroid supporting and this reformulation of Thyro Biotic reflects this change.
That depends on a lot of factors including what type of probiotics you are taking, what you are taking them for, and what other therapies you are combining them with.
Research and personal experience suggest that dosing in the 5-20 billion range is sufficient for most people to obtain therapeutic benefits but higher doses, in the range of 25 to 100 billion CFU, have the potential to provide additional benefits for harder-to-treat conditions like thyroid disease, overgrowth syndromes, weight loss, and more.
I’ve formulated Thyro Biotic with 60.32 billion CFU/serving* for several reasons:
- It provides therapeutic doses for each individual species.
- It can be easily doubled to get up to ~120 billion CFU to help with weight loss.
- It can be easily cut in half for those people who are sensitive or for those who desire to take less.
- It’s a manageable dose that’s easy to take and doesn’t require much effort on the part of the patient.
In general
*at the time of manufacture.
While the dosing of probiotics is certainly important, emerging research is pointing to the fact that bacteria diversity may be a more important metric to look at so I wouldn’t get too hung up on CFU dosing.
Probiotics are one of those types of treatments that you will want to play around with to see what works best for your body and your schedule.
They can be taken with food, on an empty stomach, right before bed, right when you wake up, etc.
One time of day is not necessarily better than the other because just about everything you do will impact what is also happening in your gut whenever you take your probiotics.
For this reason, I recommend playing around with the time of day that you take your Thyro Biotic to see what works best and to see what kind of additional benefits you can get.
