What are Peptides?

Peptides are short chains of amino acids linked together by peptide bonds. Think of them as smaller, more targeted versions of proteins. Because of their smaller size, peptides can be more easily absorbed by the body, allowing them to carry out specific functions with high precision. They act as signaling molecules, instructing other cells on what to do, which plays a crucial role in a wide range of bodily functions, from regulating hormones and reducing inflammation to promoting cellular repair and supporting metabolic health.
