And research shows that collagen peptides can increase the production of own collagen in the body1 by stimulating fibroblasts, the same cells that produce collagen and elastin. As a result, these collagen supplements can maintain skin elasticity, hydrate and smooth texture (such as fine lines and wrinkles)2.

Another double-blind, randomized, placebo-controlled clinical trial found that participants the moisture level in the skin was seven times higher3 than those who did not take collagen supplements.

Sounds great, doesn’t it? However, not all collagen supplements are truly skin-repairing. Be sure to find a formula that contains 10 to 20 grams per serving, contains nutrients that support collagen production through other pathways (such as vitamin C), and has a clean ingredient list (aka no artificial colors, sweeteners, flavors, fillers, etc.). .).
