The Science of Decline
After 40, Your Biology Changes.
The cellular systems that once kept you sharp, energized, and resilient begin to fail. This is not aging — this is biology. And biology can be addressed.
NAD+ Decline by Age 50
NAD+ is the coenzyme that powers every cell in your body. By age 50, levels have dropped by half — crippling energy production and DNA repair. This is the single most impactful cellular change that occurs in midlife.
Mitochondrial Efficiency Lost
Your mitochondria are your cellular power plants. By midlife, they produce 40% less ATP — the energy currency your brain, heart, and muscles run on. Less ATP means less of everything: focus, strength, recovery, drive.
Higher “Inflammaging” Markers
Chronic low-grade inflammation triples between ages 40 and 60, silently accelerating cellular damage throughout the body. It is the invisible force behind nearly every age-related decline.

The Science Behind YouRenew
Your Cells Know How to Thrive.
They Just Need the Right Signal.
Every product in the YouRenew protocol is built around a single principle: give your body the compounds it already understands, at the concentrations that matter.
NAD+ Declines With Every Decade
NAD+ (Nicotinamide Adenine Dinucleotide) is the molecule your cells use to produce energy, repair DNA, and regulate hundreds of metabolic processes. It is not optional — it is foundational.
By your 40s, your NAD+ levels have already dropped by roughly 50% from their peak. By 60, they can fall to a third of what they were at 20. This decline is not a symptom of aging — research increasingly suggests it is a primary driver of it.
NMN: The Direct Precursor to NAD+
NMN (Nicotinamide Mononucleotide) is the most efficient precursor to NAD+ identified in longevity research. Unlike NAD+ itself, NMN is small enough to be absorbed directly into cells, where it is rapidly converted into NAD+.
Peer-reviewed studies from Harvard, Washington University, and the University of Tokyo have demonstrated NMN's ability to restore NAD+ levels, improve mitochondrial function, and support healthy aging markers in both animal models and human trials.
Explore Genesis NMN →Cellular Energy Production
NAD+ is the essential cofactor in the mitochondrial energy cycle. Restoring NAD+ levels directly supports ATP production — the currency your cells use for every biological function, from muscle contraction to cognitive processing.
Yoshino et al., Cell Metabolism, 2018
DNA Repair & Longevity Pathways
NAD+ activates sirtuins — a family of proteins that regulate DNA repair, inflammation response, and cellular stress resistance. Sirtuin activation is one of the most studied mechanisms in longevity science, linked to extended healthspan in multiple model organisms.
Imai & Guarente, Trends in Cell Biology, 2014
Cognitive Function & Mental Clarity
The brain is one of the most metabolically demanding organs in the body. NAD+ depletion is associated with neuroinflammation and cognitive decline. Restoring NAD+ levels has been shown to support neuroprotection, synaptic plasticity, and mental sharpness in aging populations.

We Back This Product.
Completely. For 60 Days.
Real cellular change takes time. We know that. So we give you the time to actually feel it — and we stand behind every day of it.
Guarantee
NMN Is Not a Stimulant. It Is a Restoration.
Most supplements promise results in days. We are not most supplements. NMN works by replenishing NAD+ at the cellular level — a process that unfolds over weeks, not hours. Most customers begin noticing meaningful changes in energy, mental clarity, and recovery somewhere between weeks four and eight.
That is why we offer 60 days — not because we have to, but because we want you to have enough time to actually experience what Genesis does. We are confident in the science. We are confident in the quality. And we are confident in you giving it the time it deserves.
If after 60 full days you are not satisfied — for any reason — contact us and we will refund your purchase in full. No return required. No explanation needed. No questions asked.

GMP Certified Facility
Manufactured in an FDA-registered, GMP-certified facility — the same production standards applied to pharmaceutical drugs, not food products.
Independent 3rd Party Testing
Every batch is independently tested for potency, purity, and the absence of heavy metals and contaminants. We do not ask you to take our word for it.
Made in the USA
Proudly manufactured in the United States. Domestic production means tighter quality control, full traceability, and standards that overseas manufacturing cannot consistently match.
Clean Label. No Compromises.
No fillers, no proprietary blends hiding underdosed ingredients, no unnecessary additives. What is on the label is in the capsule — at the dose the research supports.
"We built YouRenew because we believe the science of longevity should be accessible to everyone. And we back that belief with 60 days and your money."
