Study, Trial or Testing Result Summary
Members OnlyHuman studies
We found no human studies that test MYO-C or its listed herbs for women's hormone health. The label lists one proprietary blend of 1912 milligrams per serving. The store listing names barley, black walnut hulls, broad beans, flax, green ginger, horsetail, papaya, peppermint leaf, sarsaparilla, saw palmetto, sesame seed and white mustard. Because every herb sits inside the blend, the amount of each one is hidden. Members cannot tell whether any of them is taken at a dose that has ever been studied. No research findings for these ingredients were provided for this goal, so we cannot say whether the formula affects hormone balance, cycles or related symptoms. We also could not find written customer reviews of this product. The praise we found is about the Pure Herbs company in general, mostly its customer service and product quality, and says nothing about whether MYO-C works. Treat any benefit for women's hormones as unproven. Check the label for allergens such as mustard, sesame and flax, and speak with a health professional before use, especially if you are pregnant, take hormone medicines or are being treated for a gynecological condition. Animal and cell studies are never counted.

Members Only4,700 reviews · 93% positive
I could not find any customer reviews written specifically about MYO-C. The Amazon and eBay listings, the Life Toniq retail page and the Pure Herbs pages show product details but no written buyer comments. The feedback below therefore comes from reviews of the Pure Herbs brand as a whole, on sites such as Birdeye and Trustburn, and it may not reflect this product. Reviewers praise the company's herbal products, with several saying the products are "the real thing" and that they have used them for years. Some say the products helped them personally. Many also describe the customer service as knowledgeable, helpful and responsive. Other reviewers call the quality outstanding, and a few describe the brand as their go-to source for herbal remedies. Criticism is rare in what I found. One reviewer simply rated the company as average, with no specifics given. These reviews are brief, and none describes muscle gain, recovery, the taste of the liquid or the dosing routine. I found no complaints about side effects, price or bottle size either. The roughly $40 price for 4 oz may matter to buyers, but no one in the sources I found commented on it. Even the brand-level praise is mostly short and general, so it says little about whether MYO-C works. Anyone considering it should read the label for allergens and treat results as unproven, since I found no clinical evidence for this formula.
Biohacker Summary
Members Only7 of 10 recommend it
The product's main ingredient, myo-inositol, did not come up in any panelist's statements, so we cannot say what the panel thinks of it. The panel only spoke about two smaller ingredients in this product, flax and barley. On flax, opinion is split: one panelist recommends it for soluble fiber and pairs it with avocado, another puts flax oil in a daily smoothie for healthy fats, and one recommends it only briefly for women low in estrogen. Three panelists warn against flax or stopped it, citing its estrogen-like effect, joint pain, and the poor conversion of plant omega-3s, and they say men and women with perimenopause issues should avoid it. On barley, the panel is mostly neutral, praising its fiber and blood sugar effects, though one panelist dropped it for chickpeas and another says to skip it if you may be gluten sensitive.

Thomas DeLauer · Flax · recommends
- Recommends using flax along with avocado in the same meal to feed the same microbes and compound the positive effects on gut health.
- Observes that Scandinavians consume barley over refined grains as part of their diet, which is linked to their long lifespan and healthspan.
- Recommends getting soluble fiber from flax, noting that while some might negate it due to being phytoestrogenic, it's a good omega-3 source.
- Barley is a better source of beta-glucans than oats.
- Recommends flax as a soluble fiber to bind to plastics and help excrete them from the body.
- Recommends flax for gut health, highlighting its soluble and insoluble fiber content which the microbiome loves, leading to improvements in insulin sensitivity and changes in numerous gut bacteria species.
- Recommends flax as a source of soluble fiber for keto.
- Recommends flax as a source of soluble fiber to help eliminate microplastics.
- Lists flax as an example of soluble fiber.
- Recommends flax for reproductive system health, explaining that its lignans are broken down by the gut into compounds that mimic estrogen, binding to receptors and reducing overall estrogen binding, which can be beneficial for women in certain cases and for men with high estrogen levels.
- Recommends flax polysaccharides for their a med-like effect, which reduces body fat percentage, abdominal fat, and removes leptin resistance by inhibiting inflammation and recovering satiety through GLP-1 upregulation.
- Recommends a little bit of flax for soluble fiber intake.
- Recommends trying barley, even though it contains gluten, because it elevates glucagon-like peptide 1 (GLP-1), which modulates glucose and stabilizes hormones and energy fuels, potentially helping with metabolic issues often associated with gluten sensitivity.
- Mentions that Nordic people consume a lot of barley, a pseudo-cereal, which contributes to their high intake of soluble fiber.

- Dr. Berg states that dark brown urine can indicate excessive Fava Beans.

Members OnlyBody systems · Combine with · Possible side effects
Body systems: Reproductive system, Endocrine system
Combine with: For its actual purpose (hormonal and metabolic balance in women), myo-inositol is often paired with D-chiro-inositol in the physiological 40:1 ratio, plus folate (methylfolate), vitamin D3, magnesium, and zinc to support insulin sensitivity and ovulatory function. Omega-3 fatty acids, berberine, and chromium can add glucose-metabolism support, and N-acetylcysteine (NAC) has been studied alongside inositol in PCOS. If the user still wants cellular and DNA repair support, they would need a separate product with NMN or NR, resveratrol or pterostilbene, CoQ10 or PQQ, alpha-lipoic acid, and glutathione or NAC. Consult a healthcare provider before combining, especially if on meds, pregnant, or trying to conceive.
Possible side effects: No major side effects reported. The product contains common allergens such as mustard, sesame and flax.
