Despite the name, this product's headline hair and skin ingredients fall well short of clinical doses. **Collagen** is listed at just 50 mg in an unhydrolyzed gelatin form — clinical studies use 2,500–10,000 mg of hydrolyzed peptides, so you're getting roughly 1% of a studied dose. **Biotin** at 5,000 mcg is the one ingredient at a meaningful level, though research supporting biotin for hair growth is largely limited to people with actual deficiency.

**Vitamin D3** at 1,000 IU hits the minimum clinical threshold, and the formula includes a basic spread of B vitamins — though all use budget forms like cyanocobalamin and folic acid rather than their bioactive counterparts. **Magnesium** is dosed at 50 mg in oxide form, which has roughly 4% absorption, giving you very little usable mineral. **Zinc** at 7.5 mg lands at half the minimum supplement range.

The biggest gap is the one that matters most for a hair, skin, and nails product: the collagen and supporting ingredients are dosed so far below clinical ranges that they won't meaningfully contribute to skin or hair outcomes. You're essentially getting a basic multivitamin with a high-dose biotin add-on.
