Control Your Thyroid Antibodies

Is using Hashimoto’s Ab Rx guaranteed to normalize your thyroid antibodies, bring your thyroid function back to normal, and kick your Hashimoto’s into remission?

Definitely not.

But it is a Hashimoto’s antibody support supplement that contains ingredients that have been shown in at least one double-blind placebo-controlled study to positively impact thyroid antibodies, thyroid function, and metabolic parameters like BMI.

When you consider that there are very few treatments designed to help support and lower thyroid antibodies, it’s apparent that research studies like the one cited above should be taken seriously by patients with Hashimoto’s.

And this was the entire reason that I created Hashimto’s Ab Rx.

To give patients with Hashimoto’s something more than just the ‘wait and see’ treatment approach that most doctors recommend.

And when you purchase any supplement from Dr. Westin Childs you get the added benefit of knowing:

  • Every single supplement is third-party tested by an ISO-accredited lab for purity, contaminants, microbes, mold, and heavy metals.
  • Total transparency is the standard when it comes to reviews and opinions from people who have used our supplements (we have a 99% transparency medal from our third-party review aggregator judge.me)
  • All of my supplements are made in an FDA-inspected and GMP-compliant facility.

Thymoquinone & Thyroid Health

Hashimoto’s Ab Rx features a full-spectrum cold-pressed non-GMO black seed oil standardized to contain 3% thymoquinone, 1% P-cymene, <0.1% carvacrol, and <2% free fatty acids.

This standardization process ensures that every dose provides you with the ideal ratio of the active compounds found naturally in black seed oil at doses that are unobtainable from regular BSO supplements.

Why does this matter?

Because research shows that supplementing with nigella sativa powder (the plant used to create black seed oil)…

  • May reduce thyroid antibodies
  • May reduce vascular endothelial growth factor (a measurement used to monitor Hashimoto’s progression)
  • May reduce TSH levels
  • May increase free T3 levels
  • May reduce food intake and satiety
  • May decrease insulin resistance
  • May decrease inflammation
  • May decrease oxidative stress
  • May decrease body weight and body measurements

Hashimoto’s Ab Rx provides you with the highest possible concentrations of the very ingredients that produce these beneficial pro-thyroid effects at ideal ratios.

Why Dr. Childs Recommends It

“The unfortunate reality for patients with Hashimoto’s is that there just aren’t very many good treatments available to help put their condition into remission.

While thymoquinone is not a miracle drug, its use provides patients with autoimmune thyroiditis a researched-back ingredient to help control their symptoms, reduce inflammation, and potentially lower thyroid antibodies. If you have an autoimmune thyroid condition then you should seriously consider using this ingredient.”

Targeting The Root Cause of Autoimmune Thyroid Disease

As you probably know, Hashimoto’s thyroiditis is an autoimmune disease characterized by thyroid gland inflammation.

In simple terms, your own body is slowly but surely destroying your thyroid gland rendering it inactive.

This destruction leads to low thyroid states like hypothyroidism and dependence on thyroid medication for life (if not treated).

Treating and managing Hashimoto’s is all about stopping this inflammatory attack on your thyroid gland which is what treatments should focus on doing.

This is why so many patients focus on their thyroid antibodies.

The presence of these antibodies in your blood can be used a proxy to determine how much damage may be occurring in your thyroid gland.

High levels of thyroid peroxidase (TPO antibodies) and thyroglobulin (TgAb) tend to correlate with more thyroid gland destruction.

You would think that doctors and researchers would be pouring money and resources into finding treatments that help lower thyroid antibodies but that just isn’t the case.

The current thought from the conventional medical community is that these sorts of treatments are not a priority because one can simply take thyroid medication to ‘fix’ the low thyroid problem.

I happen to think otherwise.

My general stance is that anyone with Hashimoto’s should do everything they can to reduce their thyroid antibodies and put Hashimoto’s into remission, even if that isn’t always possible.

The reason?

The treatments used to put Hashimoto’s will not cause any harm and only have the potential to help!

The risk vs reward payoff for using these therapies is so lopsided in favor of helping that they should pretty much always be considered.

And this is one of the main reasons why I formulated Hashimoto’s Ab Rx, to give patients with autoimmune thyroid disease something else they can do as opposed to just sitting around doing nothing.

The recommended daily dose is 0.55ml (about half a dropper full) taken twice daily, in the morning and in the evening, with or without food.

If you are also using thyroid medication then be sure to take it 30-60 minutes either before or after.

It can also be used at the same time as my other thyroid and Hashimoto’s support supplements.

Yes! Even though it has the name Hashimoto’s built-in, this supplement is still beneficial for ALL thyroid conditions.

I’ve specifically targeted the supplement towards patients with Hashimoto’s but the truth is the active ingredients are helpful for everyone, even those without a thyroid.

Black seed oil and its active ingredients have been used for thousands of years to treat a variety of conditions ranging from acne, to high blood pressure, to thyroid problems, to high cholesterol, and just about everything in between.

For perspective, the Prophet Muhammad stated that “the black seed can heal every disease, except death”.

My formula draws from this ancient wisdom and increases its effectiveness multiple times over by taking advantage of recent research. 

Yes, it’s still effective for those without a thyroid!

Even though you don’t have a thyroid the powerful anti-inflammatory and antioxidant benefits will still help your body in a variety of ways.

They are all related and very similar to one another but here are the actual definitions:

Nigella sativa: Nigella sativa is the official name used to describe the plant/herb that produces black seed oil. Traditional herbalists describe the herb as the herb from heaven given its many health benefits.

For clarification purposes, the double-blind placebo-controlled trial mentioned above used nigella sativa powder, not black seed oil.

While black seed oil has not been scientifically proven to have the same benefits as nigella sativa powder, it is highly likely that their benefits would be similar given the fact that nigella sativa is the plant from which black seed oil is produced.

Hashimoto’s Ab Rx builds on this logic by standardizing the active ingredients found in the nigella sativa plant and optimizing them for their immune-boosting potential.

Black seed oil: Black seed oil is the oil produced when the seeds of the flowering plant nigella sativa are pressed. Black seed oil is said to have many health benefits that can be obtained by concentrating the ingredients found in the nigella sativa plant.

Thymoquinone: Thymoquinone is the main ingredient found in black seed oil which is said to be responsible for all of the benefits that occur when using black seed oil.

While Hashimoto’s Ab Rx contains ingredients that have been shown to be effective at helping to reduce thyroid antibodies, there’s no guarantee that this will happen in any individual.

Unfortunately, there are no guarantees in medicine even with surgeries and the use of prescription medications.

Each person is unique and may react differently to any given therapy which makes pre-determining an outcome impossible.

Even though I can’t make any promises on outcomes, I can give you some helpful advice:


When using Hashimoto’s Ab Rx with the intent to try and reduce your thyroid antibodies, make sure you combine it with diet, lifestyle changes, regular exercise, and stress management. This will increase the odds that you see the results you are looking for.

And second:

Even though your antibody levels are important, they shouldn’t be the end-all-be-all when determining if something is working. Thyroid antibodies do not always correlate with disease progression.

The black seed oil in Hashimoto’s Ab Rx has a unique mild to moderate flavor that is generally well tolerated but if you are having any issues with the taste or flavor, here are a few tips to help get it down:

  • Squirt the contents into the back of your throat and then take a drink immediately afterward. This limits the ingredients from touching your taste buds which will decrease their flavor.
  • You can dilute each serving in a small amount of water or juice and then drink the entire thing in one or two swallows.
  • Put Hashimoto’s Ab Rx in a smoothie.

This will allow you to get all of the benefits while minimizing the taste and flavor!

Thyroid function is slow to respond when compared to other hormone systems in the body.

It takes 6 weeks of daily use of any thyroid hormone or thyroid support supplement before your body will reach a steady state which means it will take this long before it completely enters your system.

It’s usually around this time that you will start to see changes in how you are feeling but I recommend using any thyroid support supplement or medication for at least 90 days before determining whether or not it’s working for you.

I’m so glad you asked!

It’s never really ideal to just take a supplement without putting in any extra effort or using it in addition to other treatments.

Yes, taking Hashimoto’s Ab Rx by itself will still be beneficial but it’s so much more powerful when combined with other changes.

Here are a few of my favorites:

#1. A whole food diet: There are many different types of diets that can help improve your thyroid health but they all have one thing in common: they include whole food. Use this resource to help you figure out which type of diet will be best for your situation.

#2. Regular exercise: Regular exercise is an easy way to improve your thyroid function and balance your immune system. Here’s how to exercise correctly.

#3. The use of supplements: I have an entire bundle designed to help those with Hashimoto’s and each supplement in this bundle focuses on a different aspect of thyroid function and immune health. Combining supplements together is always better than taking just one at a time.

#4. The use of low dose naltrexone: Using off-label medications like LDN may help reduce thyroid antibodies in certain individuals. Learn more about whether or not it’s right for you here.

#5. Getting quality sleep: Getting 8 hours of sleep is another easy way to boost your immune system and thyroid health. Here are some tips to help make that a possibility.

Combine these other therapies with your Hashimoto’s Ab Rx for the best results!

This is a great question!

I spent a lot of time researching black seed oil and thymoquinone before formulating this supplement and here’s what I found:

There’s no question that black seed oil provides many health benefits and there’s no shortage of black seed oil supplements available on the market but the problem is that they don’t even report the active levels of thymoquinone in their products.

The majority of those products contain less than <0.1% of thymoquinone which is the active ingredient that makes black seed oil so effective.

So while using black seed oil is still somewhat beneficial, there’s no comparison to a black seed oil solution that contains <0.1% thymoquinone and one that contains 3% thymoquinone.

I formulated Hashimoto’s Ab Rx to include the highest available concentration of thymoquinone on the market which is roughly 300x more potent than most black seed oil supplements.

This provides several benefits:

#1. You get more of the concentrated ingredient per serving which means you can also more easily increase your dose.

#2. You don’t have to take as much of the active ingredient (the flavor and taste of black seed oil may prevent some people from obtaining its benefits).

#3. The 3% thymoquinone solution reduces the concentration of free fatty acids to less than 2% which further improves the benefits of thymoquinone.

Free fatty acids are found in much higher concentrations in regular black seed oil and their presence has been shown to inhibit the benefits of the active ingredients like thymoquinone.

The bottom line? If you are going to be using black seed oil for its benefits, it’s much better to get a concentrated thymoquinone supplement as opposed to using regular black seed oil.

Naturally occurring substances like plants and oils contain many different active compounds.

It’s felt that the reason these plants are so effective is that they contain many different ingredients at various concentrations and ratios.

What’s unique about Hashimoto’s Ab Rx is that its primary ingredient (ThymoQuin) concentrates these active ingredients and standardizes their concentrations to levels that ensure optimal synergy between them.

The most bioactive substances found in this formulation include:

Thymoquinone: One of the most active ingredients in black seed oil which is felt to be responsible for the majority of its health benefits. Thymoquinone must work in tandem with the other active ingredients, which is why you would never want just a thymoquinone supplement by itself.

P-Cymene: P-Cymene is a naturally occurring aromatic compound found in BSO which has been shown to enhance the anti-inflammatory effects of thymoquinone.

Carvacrol: Research suggests that standardized levels of 0.1% stabilize and enhance the anti-inflammatory effects of thymoquinone.

Free Fatty Acids (FFA): High free fatty acid levels block the inflammation-modulating effects of thymoquinone which is why the standardization process that we use reduces naturally occurring FFAs in Hashimoto’s Ab Rx.

The concentrations and doses of each have been intentionally used for better therapeutic effects.

If you are planning on using a black seed oil supplement then make sure you check on these ingredients and their concentrations!

If the concentration is not mentioned then you are most likely getting a very watered-down product.

While your antibody levels can be used as a proxy measurement of how much damage is actively occurring in your thyroid gland, they are not a perfect measurement for this.

There are situations in which antibody levels can be elevated and very little to no thyroid gland damage is occurring and there are situations in which no antibodies are absent and thyroid gland damage is still occurring.

Even though they aren’t a perfect measure of thyroid gland damage, they are still useful because they are easy to track.

However, if you are taking advantage of natural therapies and you see an improvement in your thyroid symptoms but your antibodies are not falling like they should, this is not necessarily a situation to be worried about.

The presence of antibodies simply increase your risk of developing hypothyroidism but they don’t guarantee that it will occur.

In other words, it’s still a great idea to strive to get your antibodies as low as possible but if you are unable to get them down to zero (or close to it), you don’t necessarily have to freak out, especially if your symptoms are controlled.

In short, do keep an eye on your thyroid antibody levels but don’t assume that what you are doing is not working if you don’t see those levels fall.


An analysis of 11 different studies showed that black seed oil has the potential to help reduce body weight by up to 5 pounds without the addition of diet and exercise.

This data is limited, but it is encouraging.

It’s not known why black seed oil helps some people lose weight but it’s thought to be due to its pro-thyroid effects (increasing thyroid function will impact metabolism) and its anti-inflammatory effects (obesity results in inflammation in the fat cells).

Even though it has the potential to help and some studies suggest that it may help with weight loss, I do not recommend using Hashimoto’s Ab Rx for this sole purpose.

Instead, I recommend using it as a thyroid and thyroid antibody support supplement and if weight loss occurs, well then that’s just an added plus.

Yes! Hashimoto’s Ab Rx can be used in conjunction with low-dose naltrexone.

Yes and no!

In short, this issue is not a concern because the free fatty acid concentration is standardized to less than 2% in each bottle of Hashimto’s Ab Rx.

This ensures that the active ingredients can balance immune function unimpeded by omega-6 fatty acids.

Having said that, I’m not convinced that omega-6 fatty acids from whole food sources result in inflammation.

The seed oils that cause all of the problems that everyone is aware of are heavily processed and contain high amounts of omega-6 fatty acids, and it’s this combination that is the likely culprit for the problems they cause.

Either way, though, it doesn’t matter because our standardization process reduces the omega-6 fatty acid concentration in our black seed oil.

Yes! Even though Hashimoto’s Ab Rx has the name Hashimoto’s in it, it’s still effective for those with Graves’ disease.

Both Hashimoto’s disease and Graves’ disease are autoimmune diseases and can be considered two sides of the same coin.

They are far more alike than they are different which means that many of the treatments that are effective for Hashimoto’s are also effective for Graves’ disease.

The only reason I don’t make more mention of Graves’ disease on this page is simply that there are far more people with Hashimoto’s than Graves’ disease but the fact is that black seed oil has the potential to help both conditions.

The easiest way to tell if a supplement is working or not is by paying attention to your symptoms.

If a supplement is working then you will feel a positive change in how you are feeling.

This is much different from the approach that most thyroid patients are familiar with which is to constantly check their thyroid lab tests.

Thyroid medications will definitely impact your thyroid lab tests because they contain active thyroid hormones.

Because thyroid supplements contain naturally occurring ingredients, they don’t usually have a big impact on thyroid lab tests.

Instead, they tend to work by impacting cellular functions, cell signaling, inflammation, and so on.

But here’s the deal:

Your thyroid lab tests are just a measurement of how much thyroid hormone is floating around in your bloodstream.

You don’t necessarily care about those numbers, what you care about is how those numbers are making you feel.

You should never make changes to your thyroid medication or thyroid supplements based on your thyroid lab tests unless you also put those numbers into context with how you are feeling.

Having said all of this, it’s still reasonable to keep an eye on your thyroid lab tests if you’d like to but it is by no means necessary.

The majority of the patients who have used my thyroid support supplements over the years do not check their thyroid lab tests prior to using them.

If you feel more comfortable with that approach then feel free to do it!

As with any of my supplements, I recommend that you consult with your ob/gyn or midwife prior to using any supplement while breastfeeding or while pregnant.

I know that’s a generic answer so here’s a little more information to help in your decision:

Based on available information, food doses of black seed seems to have no adverse effect during pregnancy but there are no data on higher doses (such as those found in this supplement).

For breastfeeding, black seed oil has been used by some women to increase milk supply, but again, the data is lacking and this is just anecdotal.


Hashimoto’s Ab Rx is still helpful and beneficial for patients with hyperthyroidism and Graves’ disease.

This is because the anti-inflammatory and antioxidant effects of the active compounds found inside have a balancing effect on immune function and thyroid gland inflammation.


Even though Graves’ disease causes hyperthyroidism, the mechanism by which it causes thyroid gland disease is very similar to that of Hashimoto’s which means there’s a lot of crossover in the treatment of both conditions.

In general, black seed oil and thymoquinone are very well tolerated and generally do not cause any side effects.

Rarely, it has been reported that some people experience mild nausea and mild itching when using this ingredient.

Yes! All of my thyroid support supplements can be used with all thyroid medications.

They should never be taken at the same time, though. For best results, use Hashimoto’s Ab Rx at least 30-60 minutes away from your thyroid medication (either before or after).

Unfortunately, no.

I’ve seen cases where patients have been able to put their Hashimoto’s into remission with a few minor changes like just removing gluten or taking a few supplements.

And I’ve also seen cases where patients are aggressive as possible using all available off-label medications, prescriptions, hormones, supplements, and natural therapies, and they aren’t really able to put a dent in their disease progression.

Even though it’s not always possible, I still believe your goal should be to act like it is.

The reason is that the natural treatments that have the potential to put your Hashimoto’s into remission like regular exercise, eating healthier, sleeping more, and managing your stress, are pretty much always helpful.

Don’t lose hope if you aren’t able to put your Hashimoto’s into remission, though, because you can still completely manage your thyroid symptoms with the use of thyroid medication as needed.

Awesome quality

The bottle is great, the ingredients are pristine. Please keep this formula, who cares about the taste! Medicine doesn't always taste good.

Lindsy M.
Improved sleep

The taste is strong, but I think it is worth taking. I’ve been sleeping throughout the entire night, which is something that hasn’t happened in a long time. Looking forward to seeing other benefits.

We are looking at ways to improve the taste, but in the meanwhile, we do believe in the efficacy of AbRx. Glad to hear it is helping!

Quality product

I have been taking this product for about 2 weeks and I have to say that overall I feel my well-being has improved. I will continue to take this and note any additional benefits. As far as the taste goes , I really will take anything if it’s going to improve my health so the not so great flavor doesn’t bother me. The fact that’s it’s backed by a double blind study is very exciting so I will definitely continue to take this.

We continue to work on doing what we can to improve the tolerance to taking this. It is an awesome product, and as you are already discovering, the results are worth it!

I found a way to take this!

I just started taking this. The taste and smell are awful. I ordered clear capsules from Amazon, size 00 and there are no adverse tastes or smells. I hope it is ok to take it this way. I will update my review after I finish the bottle!

Thanks for your input! We believe in the product's effectiveness... the taste can be off-putting. Would love to hear your experience.

I want it to work, but the taste…

I take a number of Dr. Child’s supplements because I’ve felt so much better on them, but this one is going to be a no-go, sadly. Really excited to try this, but I can’t get past the taste. I even tried squirting in the back of my throat as recommended and I can’t stop tasting it. Water does not cover it up. Im not saying it’s not effective; it very well could be, but I literally gag when taking this. It needs something to help with the palatability.

Hi Jennifer,

Thanks for sharing your experience! The Hashimoto's Ab Rx has a unique flavor because of its potency. Our next iteration will feature an organic olive oil base and most likely some mild essential oil to mask the flavor a bit and make it easier to consume. This should help the flavor while maintaining the potency of the active ingredients which make it so effective.

We've had a lot of people who dilute the dose in a small amount of water or juice which may be something you want to try to help get it down. If you do this, you really shouldn't taste much flavor at all.
