Startling takeaway: collagen helps your skin stay supple, but it isn’t a magic wrinkle-fixer. That’s the core lesson from a new review by Anglia Ruskin University researchers. They caution that many collagen studies rely on industry funding and often tout bold anti-aging claims. In contrast, this review is independent of industry money and presents a more nuanced picture.
Lead researcher Professor Lee Smith notes that the study gathers the strongest evidence to date on collagen supplementation. He emphasizes that collagen isn’t a universal remedy, but when used consistently over time it can offer meaningful benefits, especially for skin health and osteoarthritis. The researchers identify clear gains in certain aspects of healthy aging while also debunking some common myths about collagen.
Instead of viewing collagen as an anti-wrownkle treatment, the scientists suggest its strongest value may lie in holistic upkeep for aging skin, particularly when it’s sun-damaged. If we redefine anti-aging as a product or method intended to prevent visible signs of aging, the findings do support this notion for some measures—such as improved skin tone and moisture, which tend to create a younger-looking complexion.
Bridget Benelam, a nutrition scientist at the British Nutrition Foundation, reminds us that diet plays a pivotal role in skin health. Vitamin C supports collagen formation, so consuming citrus fruits, berries, leafy greens, peppers, and tomatoes can help. Zinc, found in meat, poultry, cheese, certain shellfish, nuts, seeds, and whole grains, also facilitates collagen production. Since many collagen products come from animal sources, vegan readers should know that there are alternative approaches: the body synthesizes collagen from amino acids found in dietary protein; plant-based proteins like beans and lentils provide these amino acids, and vegan collagen supplements are available.
Dr. Tamara Griffiths, president of the British Association of Dermatologists, welcomes the findings but urges caution. She calls for more targeted, robust dermatological studies to build on the promise highlighted by this review.
Controversial angle to consider: should the supplement industry’s role in shaping anti-aging narratives make us skeptical of bold claims, or does credible evidence still justify cautious use?
