Peptides are small chains of amino acids that are needed by the body to create proteins. They play critical role in the body as signaling molecules that regulate a variety of processes within the body. Peptides are involved in hormone regulation, immune response, cell signaling, tissue repair, muscle growth, fat loss, and anti-aging. Peptides like insulin and oxytocin manage blood sugar and social bonding, while antimicrobial peptides support the immune system and growth hormone-releasing peptides stimulate muscle growth and fat loss, and collagen to support skin and joint health. Overall, peptides are crucial for maintaining the body’s health and well-being.
