Collagen Peptides

Collagen peptides are small chains of proteins derived from collagen, the main structural protein found in animal connective tissues like skin, bones, and cartilage. They are produced by breaking down collagen through a process called hydrolysis, often using enzymes or acids. This process makes collagen more digestible and soluble.

Manufacturers add collagen peptides to foods and beverages to boost their protein content. They are often found in products marketed for their perceived health benefits, such as protein bars, fortified waters, and nutritional supplements. Their neutral flavor and solubility make them easy to incorporate into a variety of food items.

Collagen peptides are generally recognized as safe (GRAS) by the FDA for use in food. They are a source of amino acids, which are the building blocks of protein. JECFA has evaluated collagen and its derivatives, and EFSA has also assessed collagen hydrolysates. Research into the specific health effects of collagen peptides is ongoing, with some studies suggesting potential benefits for skin, joint, and bone health, though more extensive research is needed to confirm these effects.
