What Are Peptides?

Peptides are chains of amino acids—the building blocks of proteins—that function as signaling molecules within the body. These chains can be short or long, depending on how many amino acids are linked together. Short-chain peptides typically contain between 2 and 50 amino acids, while longer chains (often called polypeptides) are more structurally complex and approach protein-level function. Regardless of length, peptides serve one primary role: communication. They bind to specific receptors on cells and signal the body to perform targeted actions such as repairing tissue, regulating hormones, reducing inflammation, or improving metabolic function. In simple terms, peptides help direct your body to restore balance and operate more efficiently
