This article explains how peptide therapy is emerging as a significant advancement in anti-aging science by supporting the body’s natural processes at the cellular level rather than just addressing surface-level signs of aging. It outlines what peptide therapy is, why aging reduces peptide production, and how supplementing with specific peptides can help improve collagen production, cellular repair, hormonal balance, immune function, cognitive clarity, and metabolic health. The piece also highlights recent research trends, popular peptides used for anti-aging, and important safety and sourcing considerations for using peptides.
