Longevity Isn't Magic.
It's Biology.
Every VEYA formula is built on peer-reviewed research. Here's the science behind what we make, why the doses are what they are, and why NAD+ and NMN are at the center of modern longevity research.
Your Cells Run on
NAD+. And It Declines.
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme present in every living cell. It's essential for ATP production, DNA repair, sirtuin activation, and cellular signaling.
The problem: NAD+ levels drop approximately 50% between your 20s and your 50s. This decline is strongly linked in the research to reduced energy, slower cognitive function, longer recovery times, and accelerated biological aging.
No diet meaningfully reverses this decline. Supplementation at a therapeutic dose does — and the research is unambiguous about what that dose is.
The Papers That
Built Our Formulas.
These are the specific studies that determined our ingredient choices and dose thresholds.
Oral NAD+ raises whole-blood levels by up to 90% in 60 days
Human clinical trial: 500mg daily raised whole-blood NAD+ by 90% within 60 days — establishing the therapeutic threshold used in our formula.
NAD+ repletion reverses age-related muscle deterioration
Harvard landmark study: elevating NAD+ restored muscle function, endurance, and mitochondrial health in aging subjects. First major causal evidence linking NAD+ decline to physical aging.
NAD+ improves metabolic and cardiovascular health in humans
Double-blind human trial: oral NAD+ measurably raised blood NAD+ within 2 weeks and improved metabolic markers and vascular function in healthy middle-aged adults.
Resveratrol directly activates SIRT1 and SIRT3 longevity proteins
Sinclair's Harvard research established that Resveratrol activates sirtuins — the cellular proteins that regulate DNA repair, inflammation, and metabolic efficiency. Sirtuins are powered by NAD+.
NAD+ decline is a primary driver of multiple age-related diseases
Comprehensive review linking NAD+ decline to neurodegeneration, cardiovascular disease, and metabolic dysfunction — establishing NAD+ restoration as one of the most evidence-supported longevity interventions available.
Quercetin significantly reduces oxidative stress and inflammation
Controlled clinical trials confirm Quercetin at 250mg lowers inflammatory biomarkers and oxidative stress — creating the environment where NAD+ can drive cellular repair rather than fighting inflammation.
Two Pathways.
One Outcome.
NAD+ and NMN raise cellular NAD+ through different routes — which is why stacking them is more effective than either alone.
VEYA NAD+ — Immediate
Takes the direct route. No conversion required. Enters the bloodstream as the active coenzyme and is taken up by cells directly — particularly reliable for adults 40+ whose enzymatic conversion capacity has declined.
VEYA NMN — Biosynthesis
Works through your body's natural NAD+ synthesis pathway — the same route your biology uses. Favoured by adults 30–45 and biohackers who prefer the precursor approach. Stacks powerfully with direct NAD+.
The core coenzyme or its most direct precursor — at the clinical dose the research actually uses. Not a token amount.
Activates SIRT1 and SIRT3. NMN + Resveratrol raises NAD+ in key tissues by 1.6–1.7× versus either alone. At 98% purity.
Reduces oxidative stress so NAD+ drives repair rather than managing inflammation. In our NAD+ formula. Sophora japonica source.
Why Dose Is
Everything. Literally.
The most common failure mode in supplements isn't fake ingredients — it's real ingredients at doses that don't work. A clinical study uses 500mg. The brand puts 50mg in the bottle. The customer sees the ingredient name and assumes it's the same thing.
It isn't. Sub-therapeutic doses produce sub-therapeutic results. The research on NAD+ is unambiguous: 500mg is the threshold at which meaningful, measurable increases in cellular NAD+ occur.
We built VEYA around one commitment: our doses match the clinical literature that earned them. Not the minimum that lets us put an ingredient on a label.
The Research Is Clear.
The Dose Is Right.
NAD+ at 500mg. NMN at 99%+ purity. Resveratrol at 98% trans-form. Backed by 60 days and our full guarantee. Ships across the US.
