I tried many kinds of collagen and find this one to be the best! I love that Crucial Four products are clean and of good quality. I definitely recommend this collagen!
Crucial FOUR is your bridge to achieving the long-desired full nutrition benefits.* It's supplementing you with the four missing food groups that Big Food & Big Pharma have been hiding from you for years.* The missing food groups are: Superior Herbs, Biotic Extracts, Functional Mushrooms & Minerals. We believe in better and more sustainable ways of achieving high daily performance, ways that rely on Mother Nature's richness of vitamins, minerals and proteins; not synthetic & potentially harmful lab formulations.
