Best Anti-Aging Peptides 2026

NAD+ is widely considered the most important compound in anti-aging research due to its central role in mitochondrial function, sirtuin activation, and DNA repair. NAD+ participates in over 500 enzymatic reactions and its decline with age is a fundamental hallmark of cellular aging.

GHK-Cu is a copper-binding tripeptide that modulates the expression of over 4,000 genes. Research shows it can shift gene expression patterns toward a younger phenotype, stimulate collagen synthesis, promote wound healing, and activate tissue remodelling processes. The copper component is essential for its biological activity.

Glutathione is the body's primary endogenous antioxidant and plays a critical role in cellular defence against oxidative damage, a key driver of aging. It participates in Phase II detoxification and helps maintain cellular redox balance. Glutathione levels naturally decline with age, making supplementation a major area of anti-aging research.
