If your goal is hair, skin, and nail support, this formula targets it from three different angles with **Biotin** at 5,000mcg, **Keratin** at 500mg, and **Hyaluronic Acid** at 20mg. What this means for you: the keratin is a solubilized form (Cynatine HNS), which has a small number of studies suggesting it may support hair strength and nail integrity from within.
Biotin at this dose is meaningful only if you're deficient — in people with normal biotin levels, clinical research has not demonstrated hair or nail benefits at any dose. The hyaluronic acid at 20mg is dosed well below the 120–240mg range used in skin hydration studies, putting it at roughly 8–17% of the effective dose.
The biggest question mark is keratin itself. While the concept of supplementing the structural protein your hair is made of sounds logical, the clinical evidence is limited to a few small industry-funded trials. You're relying heavily on an ingredient that still needs more independent research.
