I'd like to start this review by making something very clear: I have spent my entire career convinced that collagen supplements and collagen drinks don't work in the way they promise to. I'm a beauty editor who takes her job of debunking outlandish marketing claims very seriously—and some collagen drinks (and other skin supplements) really take outlandish claims to the extreme.
I've done years of journalistic research into whether or not collagen drinks positively impact the appearance of skin, hair and nails in the same way as say the best cleanser or best hair mask might—and my results have largely been inconclusive. While some experts and formulators say that taking collagen supplements can leave skin healthier, more plump and glowing, and hair and nails stronger and healthier, others say there's little chance collagen supplements ever make it through the body's digestive system.
