Hydrolyzed Bovine Collagen Powder Type I & III & Hydrolyzed Porcine Collagen Powder Type I & III-Type II hydrolyzed collagen is made from type II collagen, which is the type that is most abundant in cartilage. Although hydrolyzed collagen has only recently been used to make a variety of nutritional supplements, the modified form of this protein has actually been used for thousands of years. Approximately 8,000 years ago, the people living at this time discovered that hydrolyzed collagen made an excellent adhesive. They used it as a glue to hold utensils together and to line rope baskets. The Ancient Egyptians used hydrolyzed collagen as an adhesive, and early Native Americans relied on collagen from animals to make bows. Collagen was also used in Asia as a skin care product. Over time, as more was learned about the structure of collagen and the role it played in the functioning of the human body, the medical benefits of hydrolyzed collagen were recognized. Hydrolyzed collagen was used on burn victims to help speed healing, and medical practitioners also began to use it to help them perform a variety of dental and orthopaedic procedures. Eventually, supplements that could be taken orally were developed.
While hydrolyzed collagen could theoretically be obtained from human sources, it is obvious that this would be viewed by most people as completely unacceptable. Therefore, animal sources are the next best choice.
Type II collagen is mainly found in cartilage in the human body, and this is true of animals as well. The collagen used to produce type II hydrolyzed collagen supplements is extracted from the cartilage of animals. The most common types of hydrolyzed collagen are bovine (cow), porcine (pig), and avian (chicken).
