The Science of Aging Better
Biological age is not a fixed number. The cellular processes that drive how we age — declining NAD+ levels, accumulating DNA damage, mitochondrial dysfunction, chronic inflammation — respond to what we do and what we take. The science supporting this has moved from fringe hypothesis to mainstream biogerontology, and the supplements that target these mechanisms have moved from obscure research compounds to widely used daily protocols.
Edit Your Age exists to make that science accessible without dumbing it down. This is a research-based resource for the growing number of people who take longevity supplementation seriously — who want to understand the mechanisms behind NMN and NR, evaluate the clinical trial evidence honestly, build a stack that is actually justified by the research, and not be misled by the substantial amount of hype that surrounds this space.
What We Cover
The core focus is the NAD+ ecosystem — the family of supplements that raise NAD+ levels, activate sirtuin pathways, and support the cellular maintenance systems that decline with age. NMN and NR are at the center of this, but the full picture includes resveratrol, TMG, berberine, fisetin, quercetin, spermidine, and the other compounds that appear in serious longevity stacks. Each gets a complete evidence-based treatment: how it works, what human clinical trials show, appropriate dosing, safety considerations, and how to choose a quality product.
Beyond individual supplements, the site covers how to build a coherent protocol — from a simple beginner's stack to a comprehensive multi-mechanism approach — and the lifestyle foundations that make supplementation more effective: exercise, sleep, fasting, and stress management all interact with NAD+ biology in ways the science clearly supports.
The science section goes deeper, with peer-reviewed evidence reviews of what human trials on NMN and NR actually demonstrate, mechanistic articles on the hallmarks of aging, and honest discussion of what is established, what is preliminary, and what remains unknown. The practical guides answer the specific questions people actually ask: drug interactions, cycling protocols, what happens when you stop, sex-specific considerations, and guidance for people over 60.
The Standard We Hold Ourselves To
Longevity supplementation exists in uncomfortable territory between rigorous science and marketing excess. Most sites in this space either oversell the evidence to move product or dismiss it entirely from a position of reflexive skepticism. Neither approach serves someone trying to make intelligent decisions.
The standard here is calibration. Human clinical trial data is treated differently from animal studies, which are treated differently from mechanistic reasoning. When a finding is preliminary, it is described as preliminary. When a product category has quality problems that could mean you are not actually getting what the label claims, that is covered directly. When the right answer to a question is "we don't know yet," that is the answer given.
If you are new here, the What Is NAD+ and Why Does It Matter? article is the right place to begin. If you are ready to build a protocol, the The Beginner's NAD+ Stack article is where most people start.
