Pure 500mg β-NMN — UK-Made, Independently Tested

NAD+ is a coenzyme present in every cell in the body, involved in cellular energy metabolism, DNA repair pathways and the activation of sirtuins. Published research has documented an age-related decline in NAD+ levels of roughly 1–2% per year from the third decade of life onward.

NMN (Nicotinamide Mononucleotide) is the most direct oral precursor to NAD+ in human biochemistry — after absorption it is converted to NAD+ inside cells. Human trials measuring the effect of oral NMN on circulating NAD+ have been published in peer-reviewed journals; we summarise the current evidence honestly in our blog post Does NMN Really Work? An Honest Doctor's Review.

Active Ingredients

β-Nicotinamide Mononucleotide (β-NMN) — 500mg. Independently tested purity: 95.8% (Eurofins, HPLC-DAD). Black Pepper Extract (Piper nigrum, 95% piperine).

Suggested Use

1 capsule daily, in the morning, on an empty stomach or with a light meal. Consistency matters with NMN — the published research examines extended daily dosing over weeks and months, not single doses.

For Long-Term Supplementers

If you intend to supplement long term, our NMN Pure 12 Month Supply reduces the per-month cost by over 67% versus buying monthly — the single best-value way to buy NMN in the UK.

Pair With

For a doctor-designed daily routine, NMN Pure is commonly paired with 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. Prefer NMN combined with resveratrol? See NMN Plus.
