What Are Longevity Peptides?

What are longevity peptides beginner guide — OSYRIS Health

Longevity Peptides in Plain Language

Longevity peptides and compounds are research tools studied for their effects on the biological processes that drive aging. Aging isn't a single event — it's the cumulative result of multiple cellular processes breaking down over decades: telomeres shorten, mitochondria lose efficiency, DNA damage accumulates, and gene regulation drifts.

Scientists identified these processes as the "Hallmarks of Aging" — a framework published in *Cell* in 2013 that gives researchers specific targets to study. Longevity compounds are tools that interact with one or more of these hallmarks.

The Hallmarks, Simplified

Telomere attrition. Chromosome ends shorten with each cell division. When they get too short, the cell stops dividing (senescence). → Epithalon is studied for telomerase reactivation.

Mitochondrial dysfunction. The cell's power generators produce less energy and more waste as they age. → NAD+ is studied as a cofactor that supports mitochondrial function and sirtuin enzymes. MOTS-C is studied as a mitochondrial signaling peptide.

Epigenetic alterations. The chemical markers that regulate which genes are active change with age. → Vitamin B12 supports the one-carbon metabolism pathway involved in DNA methylation.

Frequently Asked Questions

Questions About What Are Longevity Peptides?

In mouse models, some compounds (NAD+, MOTS-C) have reversed specific aging parameters like mitochondrial dysfunction. Whether any of these translate to human anti-aging effects is an open research question.

A scientific framework identifying the biological processes that drive aging: telomere shortening, mitochondrial dysfunction, epigenetic changes, and others. Published in *Cell* (2013) by López-Otín et al.

No. It's a coenzyme (dinucleotide). It's included in the OSYRIS catalog for its central role in aging biology alongside peptide-based longevity compounds.

NAD+ has the broadest preclinical evidence base, including landmark papers in cellular metabolism and aging biology. Epithalon and MOTS-C are compelling but narrower.

Because one-carbon metabolism and DNA methylation are part of epigenetic aging biology. Vitamin B12 is a cofactor in that pathway, making it relevant to aging research even though it is not a peptide.
