NMN Plus is the longevity protocol in a single capsule — 500mg pharmaceutical-grade β-NMN combined with Trans-Resveratrol, the bioavailable isomer studied for sirtuin pathway activation alongside NMN. The combination of NMN with trans-resveratrol is the protocol most closely associated with the published research of David Sinclair (Harvard) and other longevity-pathway researchers. Black Pepper Extract for absorption. Independently third-party tested. From £9.99 per month.

NMN + Trans-Resveratrol — The Most-Studied Longevity-Pathway Combination
The combination of NMN with trans-resveratrol is rooted in published research on the NAD+/sirtuin pathway. NMN is the direct oral precursor to NAD+, while trans-resveratrol has been studied for its activation of SIRT1 — the primary sirtuin enzyme. The two compounds address different points in the same biochemical pathway; published research has examined them both individually and in combination.
NMN Plus delivers 500mg of high-quality β-NMN, independently tested for purity with Trans-Resveratrol (the specific bioavailable isomer studied in the sirtuin research) and Black Pepper Extract to support compound absorption.
Why This Combination Is Studied Together
Research on the NAD+/sirtuin pathway describes NMN as the precursor that raises NAD+ levels, with trans-resveratrol acting on the sirtuin enzymes that use NAD+ as a cofactor. Trials in cell and animal models have examined the pair together; human trials with the combination are emerging. Our blog post What is Resveratrol and Why Does it Work So Well With NMN? reviews the current evidence.
Active Ingredients
- β-Nicotinamide Mononucleotide (β-NMN) — 500mg. Independently tested purity: 95.8% (Eurofins, HPLC-DAD). Made using high-quality NMN raw material, independently tested for purity.
- Trans-Resveratrol — the bioavailable, active isomer used in published sirtuin-pathway research.
- Black Pepper Extract (95% piperine).
Suggested Use
1 capsule daily, in the morning with a small amount of food (a light meal or yogurt improves trans-resveratrol absorption). Consistency over months is the relevant timeframe — the published research on these compounds examines extended dosing periods, not acute effects.
Best Value Option
For long-term supplementation, our NMN Plus 12 Month Supply at £84.99 saves over 67% versus the monthly price — the single best-value NMN supplement available in the UK.
Complete Daily Stack
NMN Plus is most often used as part of a doctor-designed daily protocol. Add Magnesium Glycinate in the evening — magnesium contributes to normal muscle function, normal functioning of the nervous system, normal psychological function and a reduction of tiredness and fatigue. Our Vital Energy Trio bundles NMN Plus with Shilajit Complex and Magnesium Glycinate.
