What NMN is, in plain English

NMN has had a strange few years. It went from a molecule almost nobody had heard of, to the darling of every longevity podcast, to being pulled off American shelves by the regulator in 2022, to being allowed back on them in 2025. Through all of that, the molecule itself did not change.

NMN stands for nicotinamide mononucleotide. It is a form of vitamin B3 that your cells use to make NAD+, a compound involved in turning food into energy and in the repair work that goes on inside every cell, all day, without you knowing. You have it in you now. The trouble is that NAD+ falls with age, roughly halving between your twenties and your fifties, and the things that get harder in middle age (recovering, sleeping properly, thinking clearly at four in the afternoon) track that fall closely. NMN turns up in small amounts in edamame, broccoli, cucumber and avocado, in quantities you would struggle to eat your way to.

We believe topping it up is one of the more sensible things you can do for a body past forty, and there are two ways to go about it. You can give the body the raw material, NMN, and let it make its own NAD+, or you can give it NAD+ itself. Our American pouch does the first. Our British pouch does the second, because the UK has not yet approved NMN as a food ingredient, and we would rather work inside the rules than around them. Same aim, same place in the scoop, two routes to the same molecule. If your label says NAD+ rather than NMN, that is why.

It is in the Summit Stack because Bear wanted it in his own, and because it made the cut when we read the research. If you take it, take it in the morning with the daily blend. That is all the instruction there is.
