Why does our product work better and faster? It is the only collagen formula on the market that combines collagen with Proteox, a groundbreaking, patented extract of salmon cartilage. That naturally contains proteoglycans – key components of connective tissues, such as cartilage, bones, tendons, and skin. So without Proteoglycans, you’re only getting half the benefits you could be getting! Proteox was shown in a randomized, double-blind, placebo-controlled clinical trials to improve skin condition and promote joint comfort and mobility.* It’s so powerful, you only need a tiny bit to have a big impact.
