NAD+ declines as you age. NMN helps restore it.

NAD+ (Nicotinamide Adenine Dinucleotide) is one of the most important coenzymes in the human body - involved in cellular energy production, DNA repair, and the regulation of hundreds of metabolic processes. The problem is that NAD+ levels decline steadily from your 30s onwards, and that decline is increasingly linked to the biological hallmarks of ageing: reduced energy, slower recovery, cognitive fog, and metabolic slowdown.

NMN (Nicotinamide Mononucleotide) is a direct precursor to NAD+. Supplementing with NMN gives your cells the raw material to produce more of it.

What the research shows

A 2022 randomised, double-blind, placebo-controlled clinical trial confirmed that oral NMN supplementation safely and effectively raises blood NAD+ levels in healthy adults. A systematic review of NMN human trials found positive effects on muscle function and insulin resistance in middle-aged and older adults. More recent research found that 12 weeks of NMN supplementation maintained walking speed, improved sleep quality, and significantly increased blood NAD+ levels compared to placebo.

The research is still maturing, but the evidence base for NMN as a practical NAD+ precursor in humans is now well established.

Why pair it with Astaxanthin?

Astaxanthin is a carotenoid antioxidant derived from microalgae - the compound that gives salmon and flamingos their pink colour, and one of the most potent antioxidants found in nature. It doesn't convert to a pro-oxidant in the body (unlike many antioxidants), meaning it can neutralise free radicals without creating secondary oxidative damage.

The pairing with NMN is deliberate: NMN works at the cellular level to support energy and repair; Astaxanthin protects those same cells from oxidative stress. Together they address two of the primary mechanisms of biological ageing simultaneously.

Astaxanthin has been studied for skin health, eye protection, and exercise recovery - with research showing benefits for UV-related skin damage, visual fatigue, and muscle soreness in active individuals.

NMN vs NR - which is better?

Both are precursors to NAD+, and both are well-researched. NR converts directly to NAD+, while NMN converts to NR first before becoming NAD+. The honest answer is that the research is still catching up - NR has a slightly longer human trial record, while NMN is now accumulating its own strong evidence base, particularly at higher doses. We stock both. If you're unsure, our NR with Astaxanthin is a good alternative to compare.
