"Healthy aging is something I'm thinking about a lot more these days. I'm always interested in where the research is headed."

People usually take it for:

  • Keeping NAD+ up, which your cells use to make energy

Tru Niagen is NR, short for nicotinamide riboside. Your body turns it into NAD+, something every cell uses for energy. Studies in people show NR raises NAD+, and scientists are still learning what that means over the long run.

Why I like it: I like following the research on aging, and I keep my expectations real.

Does nicotinamide riboside raise NAD+ levels?

Yes. Your body turns NR into NAD+, which your cells use for energy, and NAD+ drops as we age. In careful studies with healthy middle-aged and older adults, NR raised NAD+ in the blood and people handled it well. Keep it real, though: those studies show it raises NAD+. They don't show it slows aging. Nobody knows that yet. The NR study →
