Peptides derived from food proteins, such as collagen peptides, have been associated with improved muscle, bone, and skin health in humans.

Clinical trials indicate that collagen peptide supplementation can enhance physical activity levels, reduce pain, and improve skin appearance, especially with long-term use. Such peptides may support tissue repair and reduce inflammation, contributing to better musculoskeletal and mental health. These findings point to peptides as promising nutraceutical components with benefits beyond basic nutrition.
