I never even heard of nicotinamide mononucleotide. Now I have to look into it.
From the new Bing Chat:
Nicotinamide mononucleotide (NMN) is a promising molecule for therapy of diverse diseases by targeting NAD metabolism. The NAD+ production and consumption pathways including NMN are essential for more precise understanding and therapy of age-related pathological processes such as diabetes, ischemia-reperfusion injury, heart failure, Alzheimer’s disease, and retinal degeneration.
