NMN — The Precursor to NAD⁺ | Element 5

NMN — the precursor
to NAD⁺.

Nicotinamide Mononucleotide is a naturally occurring molecule that your cells convert directly into NAD⁺ — the coenzyme behind energy metabolism, cellular maintenance and the activation of sirtuins.

The molecule

What is Nicotinamide Mononucleotide?

NMN is a naturally occurring molecule made from ribose and nicotinamide. It acts as a direct precursor to NAD⁺ — a coenzyme found in all living cells, involved in energy metabolism and core cellular processes.

NMN is a precursor to NAD⁺ — a molecule involved in various cellular processes, including the activation of sirtuins, which are being studied for their role in cellular maintenance and stress response.

NAD⁺ is a coenzyme found in every living cell. It plays a central role in cellular energy metabolism and is involved in processes related to cellular maintenance and stress response.

The pathway

How NMN becomes NAD⁺

Based on a 2019 Nature Metabolism study from Dr Shin-ichiro Imai's team, NMN follows a precise route from your glass to your cells.

Why it matters

NAD⁺ naturally declines with age

Move the slider to see how cellular NAD⁺ availability is generally understood to change across the lifespan — and why a precursor strategy is studied.

Illustrative trend only. As NAD⁺ availability changes, the cellular processes it powers — energy metabolism, DNA repair signalling and sirtuin activity — are studied as part of healthy ageing research.

Why not take NAD⁺ directly?

The sofa through the doorway

The NAD⁺ molecule is too large to cross cell membranes efficiently. NMN is smaller — it uses dedicated transporters and is reassembled into NAD⁺ exactly where it's needed.

The evidence

Six human clinical trials

Real peer-reviewed research on NMN supplementation. Filter by cohort, then tap any study to reveal its findings.

How much to take

One capsule. A clinically-studied dose.

Element 5 delivers 500 mg of NMN per capsule, taken once daily with water — sitting within the ranges examined across human trials.

500 mg

Per Element 5 capsule

Once daily, with water. Research from Frontiers in Nutrition observed increased NAD⁺ after 12 weeks at 250 mg — and trials note dose-dependent effects, with larger doses yielding more pronounced increases.

Co-founder Jonny Bradley shares his protocol

Jonny had been taking NMN for 18 months, trying products from various companies. Time and again he met misleading claims and questionable transparency — so he built Element 5. Now he shares his exact healthcare protocols: a deep look into his life, habits and routines that you can follow along with, for free.
