Over 90% of Medibro subscribers are still on the same product at 3 months — the clearest signal a supplement is working.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme critical for cellular energy metabolism, DNA repair, circadian rhythm regulation, and sirtuin activity. NAD+ levels decline approximately 50% between age 40 and 60.
NMN is converted directly to NAD+ without the rate-limiting steps of precursors like niacin. Emerging research (Yoshino et al., 2021, Science) suggests NMN supplementation can raise NAD+ levels and improve insulin sensitivity in postmenopausal women.

Founded by a UK pharmacist
“After 12 years dispensing prescriptions, I was frustrated by the gap between expensive supplements and what the evidence actually supports. Medibro was built to source properly — clinical doses, verified purity, fair prices.”

Stack Synergies
Science-backed pairings for better results
Resveratrol activates sirtuins (SIRT1) which require NAD+ as a cofactor — together they amplify the longevity signalling pathway
NAD+ drives the mitochondrial redox cycle; CoQ10 is the electron carrier — stacking them restores mitochondrial function from two angles
Vitamin D3 activates >200 genes involved in cellular repair; NAD+ powers the DNA-repair enzymes (PARPs) — a comprehensive longevity foundation
Synergies based on published nutritional science. Individual results may vary. Always consult a healthcare professional before combining supplements.

Customer reviews
- ★★★★★Alfie B.04/05/2026Noticeable energy improvement
Been taking NMN for 6 weeks and the energy levels are definitely better. Feel more mentally sharp in the afternoon when I usually slump.
- ★★★★★Sarah M.04/05/2026Monthly staple now
Started with NMN after reading about NAD+ decline. Three months in and genuinely notice better stamina during workouts.
- ★★★★☆James T.29/04/2026Good quality, hard to judge results
It's hard to know what's working at the cellular level but I feel good. Would recommend based on the science.

- ★★★★☆Lily D.19/03/2026Decent product
Arrived quickly and capsules are easy to swallow. Too early to report noticeable changes but following the science.
- ★★★★★Henry I.12/03/2026Monthly staple now

- ★★★★★Professor W.L.Verified buyer27/02/2026The longevity science is compelling
Biochemist specialising in ageing. NAD+ decline is one of the most well-characterised aspects of cellular ageing. NMN is the most direct precursor. Energy levels at 62 feel closer to mid-40s. The research on NMN → NAD+ conversion in humans is now solid.
- ★★★★★George M.18/02/2026Monthly staple now
Started with NMN after reading about NAD+ decline. Three months in and genuinely notice better stamina during workouts.
- ★★★★☆Diana S.Verified buyer05/02/2026Subtle but consistent improvements
Energy, mood, and cognitive clarity all slightly but consistently better over 3 months. Blood test showed improved metabolic markers. Not a dramatic single change but consistent improvement across multiple areas.
- ★★★★☆Harry G.31/01/2026Decent product
Arrived quickly and capsules are easy to swallow. Too early to report noticeable changes but following the science.

- ★★★★★Carol M.Verified buyer16/12/2025Energy at 58 like I was 40
Read David Sinclair's research on NAD+ and ageing. Tried NMN at 500mg and the energy improvement is real. Less afternoon fatigue, clearer thinking, gym performance comparable to my 40s. This is serious science.
- ★★★★★Alan W.Verified buyer26/11/2025Mitochondrial function improved
Athletes see mitochondrial decline with age. NMN at 500mg daily has improved my endurance at 52 in ways I can measure — VO2 max is up, recovery faster. The mitochondrial support mechanism is well-established.
- ★★★★★Kenneth P.02/10/2025Worth the premium price
Expensive supplement but the mechanism is sound and the effects are real. After 4 months the subjective age-related energy decline has reversed somewhat. Proprietary encapsulation maintains stability.
