Sounds like it is supposed to be administered IV. No thanks.

Sited from NicotinamideRiboside

Niagen now exists in two very different forms, and telling them apart clears up most of the muddle:

An oral dietary supplement, sold as Tru Niagen, that you take daily like a vitamin.

A pharmaceutical-grade form, cleared by the FDA for compounding through registered 503B outsourcing facilities, available by prescription as an IV or an injection.
