Cellular ageing isn't one thing. It's at least eight things happening in parallel: telomere shortening, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and others. SRW (Science Research Wellness) is one of the few brands targeting this complexity systematically rather than picking one buzzword.
NMN and NAD+ explained simply
NAD+ (nicotinamide adenine dinucleotide) is the molecule your cells use to convert food into energy. Levels drop ~50% by age 50. Lower NAD+ means slower mitochondrial function — translating into the visible signs of ageing: fatigue, slower recovery, reduced cellular repair.
NMN (nicotinamide mononucleotide) is the precursor your body converts into NAD+. Supplementing NMN raises NAD+ levels in tissue.
Why SRW's approach is different
SRW doesn't just sell NMN. They formulate against the broader "Hallmarks of Ageing" framework first published in Cell in 2013 and updated in 2023. Their range maps each formulation to one or more hallmarks:
- Cel² Cellular System Nourishment — mitochondrial energy support
- Celᵉ Cellular Essential — broad cellular maintenance baseline
- Skl¹ Skeletal System Mobility — joint and connective tissue ageing
- Rpr¹ Men's Health — hormonal and reproductive cellular health
What to expect from a 90-day cellular protocol
Cellular changes don't show up like skincare results. Most users notice:
- Improved recovery from exercise (weeks 4–6)
- More stable energy through the day (weeks 6–10)
- Reduced morning stiffness if joints were a concern (weeks 8–12)
Where SRW comes from
SRW is a New Zealand-headquartered company 🇳🇿, founded by molecular biologist Greg Macpherson. Formulations are reviewed by their scientific advisory board including longevity researchers.
Frequently asked questions
Is NMN safe long-term? Current human studies (up to 12 months) show good safety. Multi-decade data doesn't yet exist for any longevity supplement.
Can I stack SRW with collagen? Yes. They target different systems and don't interfere.
Best time to take Cel²? Morning, with food. The B-vitamin component can affect sleep if taken in the evening.
