Unless I have not overlooked any, I think that almost every dietary supplement with collagen, currently available on the market, contains hydrolyzed collagen. A big plus for everyone. It definitely makes sense to start adding collagen as a dietary supplement, since the absorption of hydrolyzed collagen is much better than the absorption of collagen from food. 90% of hydrolyzed collagen is absorbed when in the form of a dietary supplement, opposed to only 27% absorption from food sources. When our body gets to a certain age, it produces less collagen, so the need for nutrient rich food with antioxidants, minerals, vitamins and proteins is greater. I actually copied this last sentence from somewhere. In reality, it is important to consume nutrient rich foods at all stages of life, right?
