COLLAGEN SUPPLEMENTS: DO THEY ACTUALLY WORK?
Share
Collagen is the protein that makes up around three quarters of the dry weight of human skin, helping it to remain firm, supple, and plump. It decreases with age, accelerating sagging and wrinkling. This lost protein is what hydrolysed collagen supplements (animal derived or vegan) promise to replace.
But does it really work?
Some studies show that taking collagen supplements for several months can improve skin elasticity, (i.e., wrinkles and roughness) as well as signs of aging. Others have shown that consuming collagen can increase density in bones weakened with age and can improve joint, back and knee pain. But many of these studies are small and funded by companies that make the product, increasing the opportunity for bias in the results.
The review found some data from double-blind placebo-controlled studies to support that collagen could increase skin elasticity, collagen density and overall hydration. But a lot more evidence is needed.
