NMN and NAD+: a simple guide to how it works
If you’ve started reading about healthy ageing, you’ve probably come across two acronyms that keep appearing side by side: NMN and NAD+. They sound technical, but the idea behind them is fairly simple. Here’s a plain-English guide to what they are and how they fit together.
What is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. Think of it as a helper molecule your cells rely on to turn the food you eat into usable energy, and to carry out everyday maintenance and repair. It’s one of the most important molecules in the body — without it, cells simply couldn’t function.
The catch is that NAD+ levels naturally decline as we get older. Researchers have measured this fall in human tissue over the decades of adult life, which is part of why NAD+ has become such an active area of study in the science of ageing.
Where does NMN come in?
NMN (nicotinamide mononucleotide) is a precursor to NAD+ — in other words, it’s one of the building blocks your body uses to make NAD+. When you take NMN, your body can use it to help top up its NAD+ levels.
That’s the whole premise in a sentence: NAD+ matters, it declines with age, and NMN is one way people choose to support it.
How do you take it?
Most people take a single daily capsule with water, ideally in the morning with food. It’s designed to be a simple, consistent habit rather than something you take occasionally. Our capsules are 500mg of high-strength NMN, made in the UK with Oxford Vitality and third-party tested every batch.
- Be consistent. NMN is a long-term daily habit, not a quick fix. The benefit comes from keeping it up.
- Pick a time you’ll remember. Pairing it with breakfast makes it easy to stick to.
- Give it time. Supplements work gradually, and everyone is different.
What should you realistically expect?
It’s worth being honest here: supplements are not magic, and results vary from person to person. NMN is best thought of as one part of a broader approach to ageing well — alongside good sleep, movement, and a balanced diet. If you’d like to see a rough week-by-week guide to starting out, our product page includes a simple ‘what to expect’ timeline.
The bottom line
NAD+ is a coenzyme your cells depend on, and it falls as we age. NMN is a precursor your body can use to support its NAD+ levels. If you’re curious to try it, a single daily capsule is all it takes to get started.
