Viviscal's entire clinical reputation rests on one ingredient, and it delivers. **AminoMar Marine Complex** at 450mg hits the exact dose used in multiple hair growth RCTs showing reduced shedding and improved hair density over 3–6 months. This proprietary marine protein extract is the reason to consider this product — it's one of the few hair supplements with published trial data behind it.
The supporting cast adds some value but falls short of clinical ranges. **Zinc** (11mg) and **Iron** (10mg) both matter for hair health — especially if you're deficient — but both use poorly absorbed forms (zinc oxide and ferrous fumarate). The included **Vitamin C** (59mg) helps your body absorb that iron, a useful pairing, though the dose is modest. **Biotin** at 120mcg provides roughly 12% of the minimum dose studied for hair benefits, so it's essentially a label inclusion rather than a therapeutic contributor.
This is an AminoMar delivery vehicle with mineral support on the side. If you're buying it, you're buying it for the marine complex at the right dose — and on that front, it delivers.
