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. It is more expensive than #3 Biotin for Hair Growth per gram, yet offers no definitive advantage over consuming an apple (vitamin C) for collagen synthesis. The body breaks it down into amino acids—this supplement is 90% less specific than the body's own repair mechanisms.
