What is Hydrolyzed Collagen A Hydrolyzed collagen has been used during cooking for over 100 years, and has been known to improve hair quality and to strengthen hair. Knox gelatin was one of the first companies to commercially promote hydrolyzed collagen, or gelatin, as a food product. B Hydrolyzed collagen is collagen that is derived from bovine bone and cartilage. Usually, the bone is crushed, ground, defatted, soaked in acid to remove the calcium, soaked again to break the collagen bonds and then dehydrated. This process results in small, intact amino acids which have not been damaged. These amino acids are quickly absorbed into the bloodstream, and are used as the building blocks of new collagen. C Hydrolyzed collagen is composed of small amino acids, which help form new collagen in the body. While there is currently no evidence supporting its many claims, some suggest hydrolyzed collagen is capable of increasing lean muscle mass stores, treating arthritis, and even rebuilding certain organs. There are currently no known side effects, but doctor referral is recommended.
