Peptides are short chains of amino acids that regulate important functions such as hormone activity, immune defense, tissue repair, and digestion in the human body.

Peptides, smaller than proteins, serve as messengers that tell cells when to produce hormones, repair tissues, or reduce inflammation. The body naturally produces countless types, each with specific roles. For example, insulin is a peptide that controls blood sugar, and growth hormone peptides aid muscle recovery. This fundamental role makes peptides essential for maintaining health and responding to bodily needs.
