How Tru Niagen® 300mg Works
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell of the body and is essential for energy metabolism, DNA repair, and cellular communication. NAD+ levels naturally decline with age — as well as in response to lifestyle stressors such as poor diet, excess alcohol consumption, overtraining, immune stress, and excess sun exposure. Nicotinamide riboside chloride, marketed as Niagen®, is a patented, naturally occurring form of vitamin B3 that the body converts efficiently into NAD+. Research demonstrates that NR crosses cell membranes more readily than other NAD+ precursors such as NMN, niacinamide, or niacin, making it one of the most effective ways to replenish declining NAD+ levels. Tru Niagen® has achieved regulatory acceptance by the U.S. FDA twice as a New Dietary Ingredient (NDI) and once as Generally Recognized As Safe (GRAS), and is backed by more than 500 published scientific studies, 40+ clinical trials, and a Nobel Prize–winning scientific advisory board.
