Best Peptides for Longevity & Anti-Aging
Telomerase activators, mitochondrial peptides, and cellular health compounds studied for aging
Longevity peptides target the fundamental mechanisms of aging — telomere shortening, mitochondrial dysfunction, cellular senescence, and oxidative stress. This is a rapidly evolving research area with compounds ranging from the well-studied (Epitalon) to cutting-edge mitochondria-targeted peptides (SS-31, MOTS-c).
The evidence varies considerably. Epitalon has decades of Russian research behind it, while mitochondrial-derived peptides like MOTS-c and Humanin are relatively new discoveries with mostly preclinical data. We present what the science actually shows for each compound.
Longevity & Anti-Aging Peptides (7)
NAD+
NAD+ (nicotinamide adenine dinucleotide) is a critical molecule found in every living cell. It is essential for mitochondrial energy production, DNA repair, and cellular metabolism. NAD+ levels naturally decline with age, and supplementation is being studied for anti-aging and metabolic health benefits.
Epitalon (Epithalon)
Epitalon is a synthetic four-amino-acid peptide studied primarily in Russia. Research focuses on activating telomerase (an enzyme that maintains chromosome caps), supporting pineal gland function, and potential anti-aging effects.
MOTS-c
MOTS-c is a 16-amino-acid peptide produced by mitochondria (the energy centers of cells), encoded in mitochondrial DNA. It was the first mitochondrial peptide to enter clinical trials. Research focuses on metabolic health, exercise performance, and longevity, with natural levels declining with age.
SS-31 (Elamipretide)
SS-31 (Elamipretide) is a four-amino-acid peptide that targets and concentrates in the inner membrane of mitochondria (the energy centers of cells). It is being developed for mitochondrial diseases, heart failure, and age-related conditions.
Glutathione
Glutathione is a three-amino-acid peptide made naturally in every cell from glutamate, cysteine, and glycine. It neutralizes damaging molecules, supports mitochondrial energy production, and helps the liver process toxins. Levels fall with age and chronic illness, making it a widely studied target for antioxidant and anti-aging research.
Humanin
Humanin is a 24-amino-acid peptide produced by mitochondria (the energy centers of cells), encoded in mitochondrial DNA. It was discovered for its ability to protect brain cells from amyloid-beta toxicity, a hallmark of Alzheimer's disease. Research explores its roles in brain protection, metabolic regulation, and cellular stress resistance.
FOXO4-DRI
FOXO4-DRI is a 43-amino-acid synthetic peptide that selectively eliminates senescent cells, the aged and damaged cells that accumulate in the body over time. All evidence comes from cell culture and animal studies. No human clinical trials have been conducted.
