If you're buying this for hair, skin, and nails, the headline is **Biotin** at 5,000mcg — the top of the supplemental range. The honest catch is that biotin only reliably improves hair and nails in people who are genuinely deficient, which is uncommon. There are no RCTs showing it grows hair in people with normal biotin levels, so for most users this high dose does less than its size on the label implies.

Where you're better served are the actives with real backing. You get 15mg of **Zinc** paired with 1mg of **Copper** — a balanced ratio that matters because zinc on its own can deplete copper, and both genuinely support hair and skin. **Vitamin A** sits at 1,500mcg, the top of its range for skin, and 200mg of vitamin C gives you collagen support, just under the 250mg most studies start at. A full B-complex at standard doses rounds it out for everyday energy.

The biggest unknown is the 1,200mg Maxi Blend — MSM, L-cysteine, horsetail silica, and PABA, the ingredients carrying most of the hair-specific marketing. It's listed as a proprietary blend, so you can't see how much of each you're getting or whether any reaches a dose studied for hair or nails. You take four capsules daily, so plan for that pill count if this becomes a regular.
