The use of collagen peptides for skin health is a widely studied field. Meta-analyses, including those published in the International Journal of Dermatology, confirm that oral collagen peptide supplementation can improve hydration and elasticity, and reduce visible wrinkles after several weeks. Vitamin C is an essential cofactor for endogenous collagen synthesis, making this combination biologically coherent and supported by mechanistic studies. However, the dose recommended by Bryan Johnson (20-30g) is significantly higher than the doses generally used in clinical studies, which often range between 2.5g and 10g per day to achieve significant effects. While the safety of these high doses is probable, the idea that a massive additional intake guarantees proportionally better results is not established by current scientific literature. It is, therefore, a personal optimization that exceeds the standard recommendations proven by randomized controlled trials (RCT).
