Collagen supplements fail to deliver on skin and joint health promises, study reveals

Collagen supplements have gained traction, but a 2023 meta-analysis casts doubt on their purported benefits. The study reviewed over two dozen trials and found little evidence that these products improve skin elasticity, ease joint pain, or boost overall health. Many people turn to collagen supplements hoping to target specific areas, but experts caution that collagen breaks down into basic amino acids during digestion, which may not directly benefit skin or cartilage. The meta-analysis also criticized earlier studies that claimed collagen increased skin density, citing poor methodology and deviations from scientific standards. No treatment has been proven to effectively repair damaged joints, and health professionals continue to advocate for a balanced diet over expensive supplements. Whole foods provide complete proteins that the body absorbs and uses more efficiently than isolated collagen powders or pills. The findings question the marketing of collagen supplements as a quick fix for ageing or joint issues, suggesting that consumers might find better value in focusing on nutrition. A protein-rich diet remains the most reliable way to support skin, muscle, and joint health.
