The old quest of pharmaceutical industry of one small molecule for each disease is largely over. There are perhaps different kind of strategies. For example having a symbiote organism in our body. A very simple one, the baker's yeast, which is used since centuries by women to have a good look, can generate precursors of nicotinamide riboside, and mammalian cells can take up extracellular NAD+ from their surroundings [0]. It is far from being a silver bullet, but it works. There is a long record of modifying Saccharomyces cerevisiae genome, so designing a much more effective S. Cerevisiae is not an unreasonable bet. After that it is a question of customer education, about what they can expect and not expect from a product.
