Collagen is a biopolymer, the main component of animal connective tissue, and the most abundant and widely distributed functional protein in mammals, accounting for 25% to 30% of the total protein, and even as high as 80% in some organisms. . Animal tissue derived from livestock and poultry is the main way for people to obtain natural collagen and its collagen peptides. However, due to related animal diseases and certain religious beliefs, people's use of terrestrial mammalian collagen and its products is limited, and now it is gradually turning to the ocean. developed in biology. The European Food Safety Authority (EFSA) has confirmed that even collagen derived from animal bones does not have the potential to contract mad cow disease and other related diseases. Due to the differences in amino acid composition and degree of cross-linking, the rich collagen contained in the skin, bones and scales of aquatic animals, especially their processing wastes, has many advantages that livestock collagen does not have. In addition, it comes from the ocean. Animal collagen is obviously superior to terrestrial collagen in some aspects, such as low antigenicity and hypoallergenicity. Therefore, aquatic collagen may gradually replace terrestrial animal collagen. There are many types of collagen, and the common types are type I, type II, type III, type V and type XI.

Vitamin Products is one of our best selling. Vitamin E Active Ingredients, Vitamin K2 Powder, Vitamin B6 Powder, etc. They are usually used for Healthcare Product, Nutrition Supplements... Vitamins are a group of substances that are needed for normal cell function, growth, and development. Vitamins are grouped into two categories: Fat-soluble vitamins are stored in the body's liver, fatty tissue, and muscles. The four fat-soluble vitamins are vitamins A, D, E, and K. These vitamins are absorbed more easily by the body in the presence of dietary fat. Water-soluble vitamins are not stored in the body. The nine water-soluble vitamins are vitamin C and all the B vitamins. Any leftover or excess amounts of these leave the body through the urine. They have to be consumed on a regular basis to prevent shortages or deficiencies in the body. The exception to this is vitamin B12, which can be stored in the liver for many years. Vitamin E is an antioxidant also known as tocopherol. It helps the body form red blood cells and use vitamin K. Vitamin K is needed because without it, blood would not stick together (coagulate). Some studies suggest that it is
