Great product

I have been taking this hoping to reduce hair loss - don't know if it's working as the cause of hair loss can be for various reasons. I think it has some effect, so we'll see. In any case, this is a high quality product as are all Doctor's best products.

I've been using Doctor's Best Biotin 5,000 mcg and it's a keeper. The small veggie capsules are easy on my stomach and have no aftertaste. After 4-6 weeks of steady use, my nails are harder/less peeling and I'm seeing new baby hairs along my hairline. Great value for 120 caps. What llike • Simple, vegan capsule-no fillers that upset my gut • Reliable 5,000 mcg dose (I take it daily or 4-5x/ week) • Noticeable results when l'm consistent Tips • Give it at least a month-hair/nails grow slowly • Take with food; hydrate well • If you're acne-prone, start 3x/week and adjust • Important: biotin can interfere with some lab tests (thyroid, troponin). I pause it 2-3 days before blood work. Bottom line: Affordable, easy biotin that actually helps hair and nail strength with consistent use. I'll repurchase.

Optimal dose

Good quality biotin, easy to take. Just keep in mind that the body doesn’t absorb the full 5000 mcg — studies show we only use a small part of such high doses. Still, it works well for hair and nails, and this dose is more like “extra support with a safety margin
