You're getting 10,000 mcg of **Biotin** per capsule — double the top of the typical supplement range (1,000–5,000 mcg) and over 300x the RDA. This is a mega-dose format clearly aimed at hair, skin, and nail support, and it delivers far more than you'd find in any multivitamin.

Here's the caveat that matters for you: biotin supplementation has strong clinical evidence only for people with an actual biotin deficiency, which is rare. In non-deficient individuals, there are no well-designed RCTs proving that high-dose biotin improves hair growth or nail strength. The marketing outpaces the science on this one.

Also worth knowing: high-dose biotin can interfere with certain lab tests, including thyroid panels and troponin (a cardiac marker). If you're getting bloodwork done, let your doctor know you're taking this so your results aren't skewed.
