Cellular Health, Engineered
NMN 500mg supports NAD+ synthesis — the coenzyme your cells rely on for energy, resilience, and cellular maintenance.
Energy That Compounds
Not a spike. Not a crash. Sustained cellular energy that supports consistent performance across every demand of your day.
Formulated Without Compromise
Transparent formulation. Clinical dosages. Ingredients your body can actually use.
Cellular optimisation isn't an event. It's a trajectory.
Sustained Release Technology delivers consistent NMN throughout the day. Your cells begin receiving the precursor they use to support NAD+ production — the process starts before you notice it.
As NAD+ availability is supported, mitochondrial function is supported and energy production can feel more consistent. The energy dips and mid-afternoon fog many men treat as inevitable? They don't have to be.
NAD+-dependent enzymes (sirtuins, PARP) are supported as the system reaches full depth. Recovery and mental output may begin to feel steadier.
This is what optimisation looks like at the cellular level — not a spike, not a crash. A new baseline. The engine of your prime, running as it should.
NAD+ capacity naturally falls with age. This isn't fatigue — it's biology. REIN Cellular is designed to support what time takes away.
→ Energy crashes by 2pm
→ Mental fog during key meetings
→ Slower recovery after training
→ Performance decline you can't explain
Random supplements and more coffee don't address the root cause: NAD+ depletion.

Our Cellular Synergy™ Formula combines six research-backed ingredients that work together—not in isolation. NMN creates NAD+, Quercetin protects it, and Pterostilbene + Resveratrol activate the pathways that use it. Plus Sustained Release Technology for maximum absorption. This is engineered synergy, not random stacking.
NMN (β-Nicotinamide Mononucleotide) is a direct precursor to NAD+, essential for cellular energy, repair, and metabolism. NAD+ declines ~50% between ages 30-60. NMN supports restoration at the cellular level.
B12 and TMG optimise NAD+ synthesis. Quercetin prevents NAD+ breakdown. Pterostilbene and Trans-Resveratrol activate longevity pathways that need NAD+ to work. Each amplifies the others.
Yes. HPMC plant-based capsules, no animal ingredients.
1 capsule, 3 times daily with water, ideally between meals. Don't exceed recommended dose.
Between meals for best absorption. Morning and during the day works well for daytime energy, but consistency matters more than timing.
Some men report noticing improved energy within 1–2 weeks. Broader support—recovery, resilience, sustained performance—typically builds over 4–8 weeks with consistent use.
Yes, but avoid other NAD+ precursors (NMN or NR products). If on medication, consult your healthcare practitioner.
Each bottle contains 90 capsules. At 3 capsules daily (maximum dose), this provides a 30-day supply.
REIN Cellular is generally well-tolerated. However, as with any supplement, individual responses vary. Some users may experience mild digestive adjustment in the first few days. If you experience any adverse effects, discontinue use and consult your healthcare practitioner.
Not recommended for children, pregnant or lactating women. If you are taking medication, have a medical condition, or are under medical supervision, consult your healthcare practitioner before use. Do not use supplements as a substitute for a varied, balanced diet and healthy lifestyle.
