Collagen research is very active, with more and more studies being done as we speak. That’s great news for all of us wondering about the efficacy of this unique protein. There are so many clinical trials, in fact, that they’ve been examined in robust systematic reviews and meta-analyses; this 2021 meta-analysis, for example, combined 19 different clinical trials on hydrolyzed collagen supplements and found impressive results in the name of skin aging.* When researchers systematically vetted and analyzed the results of these 19 studies, they found that hydrolyzed collagen supplementation had significantly more favorable results than the placebo in terms of skin hydration, elasticity, and wrinkles.*
“Based on results, ingestion of hydrolyzed collagen for 90 days is effective in reducing skin aging, as it reduces wrinkles and improves skin elasticity and hydration,”* researchers concluded. Translation: In just three months, participants consuming hydrolyzed collagen supplements showed noticeable and multifaceted improvements in physical signs of skin aging.*
