What the Evidence Says

✨ AI-generated · Qwen 3.6 · methodology

Marine collagen and vitamin C provide essential building blocks for skin and connective tissue support, with strong evidence for collagen's role in protein synthesis. Niacin and biotin further support metabolic function and skin health, though evidence for biotin's efficacy varies. These ingredients are generally recognized as safe for consumption.
