What the Evidence Says

AI-generated · Qwen 3.6 · methodology

Vitamin C, biotin, and vitamin B6 are associated with supporting collagen synthesis and metabolic function, though evidence for specific skin outcomes is moderate. Protein provides essential amino acids for tissue repair. Due to the very low evidence coverage of 0.3%, the overall clinical support for this specific formulation is limited.
