The speaker takes NR and NMN for increased energy levels throughout the day.

“So the short summary to this whole discussion about NR and NMN is that I take NR and NMN, but I take it because I like how it makes me feel. It increases my energy levels in the morning and throughout the day. And it does so in a way that tapers off nicely in the evening, and I can still fall asleep, et cetera. I do not take it with any expectation that it's going to increase my lifespan, simply because I don't think the data substantiating the extension and lifespan are here yet.”
