Collagen peptides can improve the condition of skin, hair, and nails, as well as accelerate the recovery of damaged tissues — this is the conclusion scientists reached after a large-scale analysis of clinical data. However, experts warn that science still has considerable work ahead before definitive conclusions can be drawn.
As reported by TUT.AZ with reference to the journal Nutrients, these results were presented by the authors of a major review of clinical studies examining the effects of collagen supplements on the human body.
International experts point out that collagen is one of the key skin proteins responsible for its firmness, density, and ability to retain moisture. Over the years, its natural production steadily declines, leading to dryness, loss of elasticity, and the appearance of wrinkles. Analysis of the accumulated scientific data demonstrated that taking collagen peptides can improve skin hydration, restore its firmness, and noticeably smooth out age-related changes.
Another conclusion by the researchers drew particular interest: the most noticeable effect was produced by low-molecular-weight peptides enriched with hydroxyproline. These compounds are significantly better absorbed by the body and are capable of initiating skin renewal processes, activating fibroblast function, and stimulating the synthesis of essential components of the extracellular matrix. Notably, according to the scientists, what matters most is not the origin of the collagen but the composition and size of its peptides.
In addition, a number of studies identified the potential benefits of collagen supplements for strengthening hair and nails. Specialists recorded increased hair thickness, accelerated nail growth, and reduced nail brittleness. Data have also been accumulated suggesting that collagen peptides may support tissue healing in cases of burns, pressure sores, and other skin damage.
Nevertheless, the authors of the review urge caution in assessments: the existing body of evidence cannot yet be considered comprehensive. A significant number of clinical studies were conducted on small participant samples, were limited in duration, or examined the effect of complex supplements that included several active ingredients at once.
