So what is NR? So NR is fairly popular, a lot of people have heard of it. It stands for nicotinamide riboside and all it is, it's just a smaller version of NMN without a phosphate on there. So there's no phosphorus on it. So if you take NR, your body has to first put on a phosphorus and then it has to basically link two of them together to make the NAD.
