The NR supplement actually backed by human trials—boosts NAD+ by over 50%
Tru Niagen's 300mg nicotinamide riboside (NR) is the NAD+ precursor with actual clinical data behind it. Chromadex's patented Niagen® form appears in 65% of registered NR trials. One capsule daily is clinically proven to increase NAD+ levels by over 50% in most people. It's designed for cellular repair and energy, though the mechanism is still being studied—not a magic anti-aging pill.
