NutricostBiotin (Vitamin B7) 10,000mcg (10mg) Vitamin Supplement, 240 Capsules - Vegetarian, Gluten Free, Quick Release, Non-GMO

Nutricost consistently ranks high on the supplement tracking app I use, and this product is no exception. It checks most of the boxes when it comes to safety and quality. The inactive ingredients are clean, and everything is made in the USA in a cGMP-certified, third-party-audited facility. It’s also NSF certified, which adds another level of trust.I appreciate the level of testing behind this—third-party verified, raw ingredient tested, purity tested, and screened for heavy metals. The only things missing are lot-specific testing and public batch COAs, but those are nice-to-haves rather than dealbreakers.The formula is free from fillers, dyes, and GMOs, which is important to me. While the founder doesn’t have a medical or scientific doctorate, that’s a minor point considering the product stands on solid quality and transparency. Overall, this is a reliable supplement from a brand I feel good about using.No smell, very easy to take, easy on the stomach, seems to have positive results.

I have noticed my hair has been growing also my nails

Love this brand. Price is great I even get more capsules than what I can get at retail store. No taste. Easy to take

In the clinical trial I conducted (n = 1), this product seemed to help address the problem of splitting fingernails. However, a confounding variable was introduced when my wife stabilized my nails with clear nail polish.Relative contributions of these two "treatments" are not quantifiable. Be that as it may, my nails are healthier.

Works for me. I can tell the difference in my hair skin and nails

easy to swallow

Great price

Not doing much for my hair, but I feel better. Go figure.
