Collagen Peptides: Should You Take Them?
Summary
Host Wendy Zuckerman investigates whether collagen peptides can improve skin health or aid injury recovery. Experts explain that ingested collagen breaks down into amino acids, making topical or oral supplements ineffective for skin rejuvenation due to poor study quality and industry bias. However, research suggests that combining collagen intake with resistance exercise may modestly boost tendon collagen synthesis. The episode concludes that while supplements offer minimal benefits, natural food sources and exercise are superior for maintaining collagen levels.
