Unfortunately, they didn't say how much of B3 is too much. I guess the RDA of 16/14 mg is ways below that threshold.

This article is not about vitamin B3 in general. It is about nicotinamide riboside, which is one of the three forms of B3. Not all supplements contain it. I’ve never seen it in any B complex supplements.
It is apparently sold as an anti-aging supplement, which exacerbates the issue since those in the anti-aging interest group are also in the "old enough to be concerned about cancers" group.
As well, NR is plant derived, versus the other two types that tend to be animal derived. So I assume vegan vitamins would be a likely product range to use NR as B3. This already occurs with vegan Vitamin D, where D2 is plant-derived, and D3 is generally animal derived.
