Collagen is found naturally in the body, makes up about 70% of protein in the skin and primarily consists of Glycine, Proline, Hydroxyproline and Alanine. Collagen is a major structural component of skin, bones, joints and tendons.* It helps maintain normal hair and nails, and supports immune function. Collagen is also the most important component of the dermis, but natural collagen production slowly begins to deplete over time. Hydrolyzed collagen or collagen hydrolysate powder is an easily digested form of pure collagen that acts as a source of amino acids for the body. This particular form is derived from fish cartilage. Marine Collagen Powder, or fish collagen powder, may support connective tissue, such as tendons, cartilage, and ligaments, and fortify the joints and promote healthy skin.* This powdered collagen may also support the muscle, bones, and cardiovascular health.* This is collagen peptide powder, or marine collagen peptides, to make it easier for the body to absorb.* This product is pure collagen powder form. It is free from any fillers or additives.
