Peptide is a kind of microelement, among which collagen peptide has various effects, such as inhibiting angiotensin-converting enzyme activity, having antioxidant activity, eliminating free radicals, reducing the pain of patients with osteoarthritis, such as knee joints or hip joints, enhancing the bone mineral density, maintaining the balance of bone metabolism and so on.

Small molecule peptides can be directly absorbed by the epithelial cells of the small intestinal villi, and these absorbed peptides have different amino acid compositions and arrangement order, and play different physiological functions in the human body.

Extended information:

Orally administered collagen peptides are able to accumulate in the cartilage after being absorbed into the circulation. This mechanism may help arthropathic patients suffering from joint disease; subjects with dietary supplementation of hydrolyzed collagen peptides were able to effectively alleviate joint pain as well as the risk of joint deterioration; and in patients with osteoporosis, calcitonin plus pharmaceutical-grade collagen peptides inhibited the breakdown of bone collagen more than calcitonin alone.

Collagen peptides have been sold and consumed for many years in the United States, the European Union, Japan and China, and their health effects have been widely recognized. Collagen peptide products are certified by China Food and Drug Administration as safe and reliable food.
