Collagen Peptides are low-molecular-weight peptides (typically 2,000–5,000 Da) obtained by controlled enzymatic hydrolysis of native collagen using specific proteases. Raw materials include bovine hides, porcine skins, fish skins, and fish scales. Unlike gelatin, collagen peptides do not gel at room temperature and are highly soluble in cold water.
This makes them versatile for beverage and supplement applications. Clinical studies support their efficacy for skin elasticity, joint mobility, and bone mineral density at daily doses of 2.5–15 g. Collagen peptides are classified as a food ingredient (not an additive) and are approved in all major markets. They carry Halal and Kosher certifications depending on the source material.
