I had not heard about this, and, frankly, no medicine should be able to take a prior substance off the market, due to competition or medical results.
There should be lawsuits over this, too.
NMN is not as well studied as nicotinamide riboside. We do take both in a combo supplement, but we prefer nicotinamide riboside, from study insights.
Chromadex/TruNiagen, which I believe is an NR, received also received an FDA letter last week that it may not sell or market as a dietary supplement. Lawsuits? Or does the product immediately come off store shelfs?
