About this supplement
Marine collagen is a type of collagen derived from fish and other marine sources. It is known for its high bioavailability and is often used in dietary supplements and beauty products to support skin elasticity, hydration, and overall skin health. Marine collagen is composed of amino acids, primarily glycine, proline, and hydroxyproline, which are essential for maintaining the structural integrity of skin, cartilage, and bones.

Physical properties
Marine collagen is typically a white to off-white powder, soluble in water, and has a neutral taste.
How it’s made
Marine collagen is produced through the hydrolysis of collagen extracted from fish skin or scales, which breaks down the collagen into smaller peptides that are more easily absorbed by the body.
