Collagen Peptides

Collagen Peptides are digested into individual amino acids just like any other protein, yet the market charges $30 to $50 per tub for a 10-gram dose that contains only 3 grams of glycine. A 2019 meta-analysis of 11 trials in the Journal of the American Academy of Dermatology found that oral collagen improved skin hydration by 12% compared to baseline, but the studies were small and often funded by manufacturers. Independent research remains split: a 2023 systematic review concluded the evidence for joint pain relief is weak, and collagen is no better than a cheaper whey protein for muscle recovery. The body breaks it down into amino acids—this supplement is 90% less specific than the body's own repair mechanisms.
