NAD+ guides
What NAD+ is, how the different ways of taking it compare, and what the research does and does not show. Every guide lists its sources.
Do NAD+ patches, nasal sprays and liposomal capsules work?
NAD+ is a large, water-loving molecule, and nobody has published what a patch or nasal spray puts into a person's blood. We go through the human evidence route by route, including for injections, which we sell.

Eight questions to put to any NAD+ supplement sold in the UK, from what is in the capsule or vial to how to work out cost per milligram. It names no brands and ranks nothing.
10 min readIs NAD+ a peptide?
NAD+ turns up in the same clinics and the same kind of vial as peptides, so people assume it is one. It is a coenzyme made of two nucleotides, and that changes how it is tested and stored.
7 min readNAD+ benefits and side effects: what the evidence shows
What each NAD+ study measured, in whom and with what limits, and the side effects that trials have recorded for IV drips, injections and oral precursors.
10 min readNAD+ injection dosage: how it is dosed and what research has used
NAD+ is sold as a food supplement, so there is no approved dosing schedule. The studies that injected it were small and short; this guide lists what each one gave and explains how to read mg and ml.
8 min readNMN vs NAD+: what's the difference?
NMN sits one enzymatic step upstream of NAD+. What that means for swallowing it, for injecting NAD+ instead, for the human evidence on each, and for where NMN stands with the Food Standards Agency.
9 min readWhy people stop taking NMN
NMN raises NAD+ in the blood fairly reliably in human trials, while most of the health measures tested alongside it have not changed. Here are the reasons people give for stopping, checked against those trials and against what regulators have said.
