Click bait headline. Should editorialize to include:

> nicotinamide riboside (NR), a form of vitamin B3

Isn't that a popular vitamin supplement? Why is it clickbait?

Readers are baited into clicking to find out the subject of the article (which supplement).

Is this a new finding or is it the same "news" that's been regurgitated through hundreds of news outlets already over the last week? The only way to find out from the headline alone would be to give this outlet some ad impressions.

Yes, especially since other articles link it to breast cancer. So this is one of those links you might click only to find out you already knew about it because of those articles.

Second order effect of establishment sources losing credibility?

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.
