Longevity science has made NMN one of the most discussed supplements of recent years, and this powder from Neurogan Health offers it in a simple, flexible format. Neurogan is a family-run Californian brand that puts clear labelling and third-party lab testing at the centre of what it does.

The 30g tub contains high-purity nicotinamide mononucleotide, a naturally occurring molecule the body uses as a building block for NAD+, a coenzyme involved in normal cellular energy processes. As an unflavoured powder rather than capsules, it can be stirred into water, juice or a morning smoothie, and makes it easy to adjust your serving. Follow the serving guidance on the label.

It suits anyone exploring the NAD+ area who prefers powders to pills and values published lab results for reassurance.
