ENERGY

Energy is rarely a willpower problem — it's a cellular one. Most people in their 40s, 50s and 60s describe a steady erosion of stamina, harder afternoons, slower recovery from exercise and a general sense that the body just doesn't generate the same output it once did. The biology behind that is well understood: NAD+ levels decline by roughly 1–2% per year from your mid-30s, and by your 50s most adults have less than half the NAD+ they had at 25. NAD+ is the coenzyme that powers cellular energy production, mitochondrial function and overnight repair. When it falls, everything that depends on it falls with it.

This collection is built around restoring that biology. Our two NMN formulas (NMN Pure and NMN Plus) are the most direct oral precursors to NAD+ available — high-purity β-NMN, independently tested for purity, designed to be taken consistently every morning. NAD+ Complex takes a complementary approach, combining multiple NAD+ precursors with magnesium and resveratrol to support the full pathway. Shilajit Complex works via a different mechanism — supporting mitochondrial function and ATP production directly — and stacks well with NMN.

For most people starting NMN, our recommendation is to take it consistently every morning, ideally on an empty stomach, and to be patient: noticeable energy improvements typically appear at weeks 2–4 and continue building over months. Doctor-designed by Dr Chun Tang, a practising NHS GP with 26 years of clinical experience. From £7.99 per month.

Frequently asked questions

How long does it take for NMN to improve energy?

Most people notice initial energy improvements between weeks 2–4 of consistent daily use, with sustained, more pronounced effects by months 2–3. NMN works at the cellular level — it's not a stimulant — so the improvement is steady rather than sudden.

Can I take NMN and Shilajit together?

Yes — they work via different mechanisms (NAD+ restoration vs direct mitochondrial support) and are designed to complement each other. Many longevity protocols pair them. Take both in the morning, ideally with food.

What's the difference between NMN Pure and NMN Plus?

NMN Pure delivers 500mg of high-purity β-NMN. NMN Plus delivers the same 500mg plus Trans-Resveratrol — the protocol used by Sinclair, Huberman and other longevity researchers, which activates the SIRT1 sirtuin pathway alongside raising NAD+ levels.
