Conversol Review (2026): Does This Liver and Thyroid Supplement Really Work?

Miavola is a wellness brand that focuses on thyroid, liver and hormone health. The brand markets its liver supplement, Conversol, as a “liver complex” that aims to support thyroid health. It is a vegan capsule supplement that contains milk thistle, artichoke, NAC, glutathione, selenium, choline, CoQ10, dandelion root and a few other nutrients. Each bottle holds 60 capsules. You take 2 capsules daily with a meal, so one bottle lasts 30 days. Prices start at $59.99* for a single bottle.

The idea behind Conversol is simple. Miavola says that around 60% of thyroid hormone conversion takes place in the liver. If the liver is not working well, your body may struggle to turn the inactive hormone T4 into the active hormone T3. Support the liver, the brand suggests, and you support that conversion.

But does Conversol really work? Can a liver supplement do anything for your thyroid? And are the doses in each serving close to the amounts used in research?

Conversol provides better ingredient transparency than many liver supplements, as the label lists most ingredient amounts. However, the details we reviewed do not specify the amounts of dandelion root and alpha-lipoic acid, and the formula contains several ingredients in lower doses than researchers typically use in studies.

There is also no published human trial on the complete Conversol formula. Some of its ingredients have been studied on their own, but that is not the same as testing the finished product.

Let’s look at Conversol’s ingredients, the science, its marketing claims, customer reviews, pricing and safety, and compare it with WOWMD® Liver Support and Gundry MD Complete Liver Support.

Conversol Ingredient Analysis

Conversol is a capsule supplement made to support normal liver function, antioxidant protection and thyroid hormone metabolism.

Each 2-capsule serving contains the following ingredients:

• Milk Thistle Extract (80% silymarin): 200 mg
• Artichoke Leaf Extract (2.5% cynarin): 200 mg
• N-Acetyl L-Cysteine (NAC): 150 mg
• L-Methionine: 100 mg
• Coenzyme Q10: 100 mg
• Choline (as choline bitartrate): 82.5 mg
• L-Cysteine HCl: 75 mg
• Reduced Glutathione: 50 mg
• Selenium (as selenomethionine): 55 mcg
• Dandelion Root Extract: amount not shown
• Alpha-Lipoic Acid: amount not shown

The formula is also vegan, gluten-free and non-GMO, and the brand says it contains no additives. Most ingredient amounts are listed, but the doses of dandelion root and alpha-lipoic acid were not shown in the details we reviewed.

Conversol contains antioxidants (NAC, L-cysteine, L-methionine and glutathione). Glutathione helps protect liver cells from oxidative stress. NAC and L-cysteine provide cysteine, which the body needs to make its own glutathione. A review on the uses of N-acetyl cysteine discusses NAC’s antioxidant properties and medical uses. However, Conversol has 150 mg of NAC, while studies often use 600 mg or more.^[1] Its 50 mg of glutathione is also one fifth of the lowest amount used in a six-month clinical trial that raised the body’s glutathione stores.^[2] Purelia Liver Restore uses the same 50 mg dose, as we noted in our Purelia Liver Restore review.

Milk Thistle is rich in silymarin, an antioxidant compound studied for its protective effects on the liver. Conversol contains 200 mg of Milk Thistle Extract standardized to 80% silymarin, which gives about 160 mg of silymarin per day. Unlike many brands, Conversol lists the silymarin level, which makes it easier to compare with research. A 2024 systematic review and meta-analysis found improvements in some liver markers, including ALT and AST.^[3] Still, the National Center for Complementary and Integrative Health reports mixed results for milk thistle in liver diseases.^[4]

People have traditionally used Dandelion Root and Artichoke for digestive and liver support. Conversol contains 200 mg of Artichoke Leaf Extract, but the product details do not specify the dandelion dosage. Artichoke has been studied for liver enzyme levels. In a double-blind trial in people with fatty liver, researchers used 600 mg daily, three times the amount in Conversol.^[5] Evidence for dandelion’s liver benefits comes mainly from experimental studies. It is hard to tell how well these two herbs work together in Conversol.

Choline is important for normal liver function and fat transport. The NIH Office of Dietary Supplements lists an adequate intake of 425 to 550 mg daily for adults, while Conversol offers 82.5 mg per serving.^[6] This contributes to your daily intake, but research has not demonstrated that it helps with fatty liver.

Other nutrients come from Selenium, CoQ10 and Alpha-Lipoic Acid. Selenium is the main thyroid ingredient. The body uses it to make proteins that play a role in thyroid hormone metabolism, according to the NIH Office of Dietary Supplements.^[7] Conversol’s 55 mcg matches the daily recommended amount for adults, but it is still unclear whether selenium supplements help treat thyroid disease. CoQ10 helps cells produce energy, and the 100 mg dose provides a reasonable daily amount. The product details do not specify the alpha-lipoic acid dosage, making it difficult to assess its role in the formula.

The biggest drawback is the low doses of several ingredients. Conversol’s active ingredients have some useful roles in the body, but modest amounts, two doses not shown and no clinical trial on the finished product make it hard to prove its liver and thyroid claims.

Scientific Evidence

Research showing that an ingredient does something useful in the body is not the same as research showing that a finished supplement works.

Conversol’s ingredients have been studied for liver function, antioxidant protection and thyroid hormone metabolism. The body uses selenium to produce enzymes that convert T4 into T3. NAC helps the body make glutathione. The liver needs choline to transport fats normally.

The liver and thyroid have a clear connection. A review in the Journal of Endocrinological Investigation explains that the liver plays a key role in activating, inactivating, transporting and breaking down thyroid hormones.^[8] Another review on liver deiodinases describes how enzymes in the liver help control thyroid hormone levels.^[9]

That connection gives Conversol a logical starting point. However, it does not prove that taking a liver supplement will improve thyroid hormone conversion in healthy people or in people with thyroid problems.

Several factors affect how a supplement may perform:

• The amount of each active ingredient
• Extract quality and standardization
• How well the body absorbs the ingredients
• How long someone takes the supplement
• Whether the person has a liver or thyroid condition
• Medication use and general health
• Diet, alcohol intake and lifestyle habits

Selenium is a good example. It is essential for thyroid hormone metabolism, but most people already get enough from food. According to the NIH selenium fact sheet for consumers, it is not yet clear whether selenium supplements help treat or lower the risk of thyroid disease.^[10]

Milk thistle is another example. A meta-analysis on silymarin found improvements in certain liver enzymes, but the researchers said more high-quality trials are needed.^[11]

Artichoke shows a similar pattern. A systematic review and meta-analysis of artichoke supplementation found that some liver enzyme levels decreased. These results do not apply directly to Conversol, since the products and doses in those studies were different.^[3]

The strongest proof would be a controlled human trial measuring T3 levels, liver enzymes or energy before and after taking Conversol. The available research does not identify any published trial of this kind evaluating the complete formula.

Overall, Conversol’s ingredients provide a reasonable nutritional base for liver and antioxidant support, but researchers still need to conduct independent human studies on the finished product.

Marketing Claims That Need More Context

“Developed for Thyroid Health”

Conversol is marketed for people who care about their thyroid. Miavola’s FAQ even covers people with Hashimoto’s, Graves’ disease and those without a thyroid.

The thyroid link comes mainly from selenium, which is part of the enzymes that turn T4 into T3. The liver also plays a role in thyroid hormone metabolism.

Supporting normal thyroid function, however, is not the same as treating a thyroid condition. No published trial shows that Conversol raises T3, improves thyroid test results or helps with hypothyroidism or Hashimoto’s.

Miavola itself advises taking your thyroid medication exactly as prescribed and using Conversol only as a supplement. It should never replace levothyroxine or any other prescribed treatment.

“Contributes to Maintaining Normal Liver Function”

This claim rests mainly on choline, which is needed for normal liver function. Milk thistle, artichoke and dandelion are traditional liver herbs found in many liver cleanse and detox supplements, and NAC and glutathione support antioxidant defenses.

These roles explain why the ingredients were chosen. But Conversol provides 82.5 mg of choline, well below the 425 mg to 550 mg adults need each day.

No published trial shows that the full Conversol formula lowers liver enzymes, reduces liver fat or helps with fatty liver disease. For fatty liver, diet, exercise, healthy weight loss and medical care remain the proven approaches. Astaxanthin is another ingredient marketed for fatty liver, and as our ClarityMD Astaxanthin review explains, its main human study had only 12 people.

“Up to 60% of Thyroid Hormone Conversion Takes Place in the Liver”

This is the core of Conversol’s pitch. The sales page says “approximately 60%” in one place and “up to 60%” in another.

The liver does play a major role in thyroid hormone conversion and breakdown, and research supports that connection. However, Miavola does not cite a source for the exact 60% figure.

More importantly, the claim assumes that your liver is the reason for poor conversion. Low T3, tiredness or weight changes can have many causes, and a supplement cannot tell which one applies to you. If you have these symptoms, talk to a healthcare professional and get tested.

“More Energy and Better Digestion”

Many Conversol reviews mention more energy in the afternoon, less need for naps or better regularity.

CoQ10 is involved in energy production inside cells, and artichoke and dandelion have long been used for digestion. These ingredients give a possible explanation for what some users report.

But customer stories do not prove the product caused these changes. Other users say they have not noticed any difference, and some reviews on other sites mention mild bloating in the first weeks.

Ongoing tiredness or brain fog should be checked by a healthcare professional, not simply blamed on the liver or thyroid.

“Manufactured and Laboratory Tested in the US”

Miavola says it manufactures and lab-tests Conversol in the United States. That is a good sign for quality.

However, we could not find publicly available batch-specific lab reports or certificates of analysis in the information we reviewed. Third-party testing results would make this claim easier to trust.

“Vegan and Without Additives”

The brand claims that it is free from additives, vegan, gluten free and non-GMO. This is perfect for those who do not eat foods derived from animals or bulking foods.

However, natural doesn’t necessarily equal correct. Side effects may be nausea, bloating, stomach discomfort, diarrhea, headache or a slight bitterness.

Milk thistle and dandelion belong to the same plant family as ragweed, so people with that allergy should be careful. CoQ10 has been linked to a weaker effect of the blood thinner warfarin in a case report, although a small controlled trial with 100 mg daily found no change. Alpha-lipoic acid may also affect blood sugar.^[12][13]

Miavola suggests a two-hour time gap between Conversol and thyroid drugs. You should check with your prescriber when you should take it.

Do not use Conversol if you are pregnant or breastfeeding, if you have any liver, gallbladder, thyroid condition or if you are taking any kind of medicine, speak to a healthcare professional first.

Our Verdict on the Marketing Claims

Conversol is a combination of milk thistle, artichoke, dandelion, NAC, glutathione, choline, CoQ10, selenium and amino acids for normal liver and thyroid function.

Some of these claims rest on solid nutrition science. Selenium is part of the enzymes that convert T4 into T3. Choline is needed for normal liver function. NAC helps the body make glutathione.

Milk thistle and artichoke have also been studied for their effects on liver enzymes.

The bigger question is how far these facts support Conversol’s thyroid-focused marketing.

No published trial shows that the complete formula improves thyroid hormone conversion, raises T3, lowers liver enzymes or boosts energy. The 60% figure on the sales page also comes without a source.

Dosing is another issue. Most are listed, which is good; but NAC, glutathione, artichoke and choline are all under the dosage level in studies, and there were no details found of two doses.

General claims about antioxidants and nutritional support are reasonable based on the ingredients.

Stronger claims about thyroid conversion and better test results need clinical proof. Conversol would be easier to judge if Miavola published all doses, shared batch test reports and ran a controlled human trial on the full product.

Conversol vs. Popular Liver Support Supplements

WOWMD® Liver Support

WOWMD® Liver Support is designed to help people who are seeking simple, daily liver support. It promotes normal liver function, antioxidants and healthy fat metabolism.

The formula combines trusted liver herbs – Milk Thistle, Artichoke Extract, Burdock Root, Alfalfa and Yarrow. People have traditionally used these herbs for liver wellness and digestive support, and many popular liver supplements contain them.

Conversol is not like that. The formula combines liver herbs with amino acids, antioxidants, choline, CoQ10, and selenium and aims to support people interested in thyroid hormone conversion.

So what should you do? It’s all about concentration.

At its core, WOWMD® focuses its formula on liver health. The brand includes herbs that aim to support liver and digestive wellness, so you know what the formula contains. Conversol has 11 ingredients and some are in smaller quantities.

Experts Advice on Conversol

Conversol is easy to fit into a daily routine, with just two capsules taken with a meal. The label is also clearer than many competing liver supplements. However, customer feedback is mixed.

On the official site, Conversol holds an average of 4.29 out of 5 from 180 reviews. One user said she no longer needed a nap after breakfast after two weeks. Another noticed steadier energy in the late afternoon. Another said she felt more regular than ever before.

Other reviewers wrote that they have not noticed any changes yet, and one said it was hard to tell whether it helped, since she takes many other supplements. Reviews on other sites mention mild bloating early on and doubts about value for the price.

These stories do not prove that Conversol works or that it does not. They do show that results vary a lot from person to person.

The low doses of several ingredients, two doses not shown and the lack of a clinical trial on the full formula make it hard to recommend Conversol with full confidence, especially at its regular price.

Final Verdict

Conversol is a capsule supplement by miavola that combines Milk Thistle, Artichoke, Dandelion Root, NAC, Glutathione, Choline, CoQ10, Selenium and amino acids. The formula aims to support normal liver function, antioxidant defenses, and thyroid hormone metabolism.

Several of these ingredients have obvious functions within the body. Selenium helps the body convert T4 into T3, while choline supports normal liver function. However, the formula contains several ingredients in lower amounts than researchers have used in studies, and no published human clinical trial has evaluated the complete formula.

Customers share mixed feedback. Some users report better energy or regularity, while others have not noticed much difference. The brand highlights thyroid hormone conversion as its main selling point, but clinical research has not demonstrated this benefit for the complete formula.

WOWMD® Liver Support offers a herbal formula with Milk Thistle, Artichoke, Burdock Root, Alfalfa and Yarrow, along with advertised third-party testing.

Gundry MD Complete Liver Support keeps things simple with Orange Peel Extract, Milk Thistle and Dandelion Root in softgels, with a 90-day money-back guarantee.
