THE SCIENCE BEHIND NAD+

Every cell in your body is fueled by NAD+

Your 37.2 trillion cells are powered by NAD+, a vital coenzyme that fuels cellular energy and repair throughout your entire body. NAD+ levels naturally decline with age, lifestyle factors, and stressors. Replenishing NAD+ levels is essential for maintaining your cellular health, energy, and vitality.

Backed by world-leading researchers

"Niagen, Niagen Bioscience’s patented nicotinamide riboside product, is one of the most well-studied, carefully controlled dietary supplements, and indeed, a gold standard in the industry."

Roger Kornberg, Ph.D.
Nobel Prize Winner in Chemistry | Mrs. George A. Winzer Professor of Medicine, Stanford | Niagen Bioscience Scientific Advisory Board Chairman

"Disturbances in NAD coenzymes can leave tissues unable to repair themselves, generate energy, and perform their normal homeostatic functions. In many conditions of metabolic stress, the genes that convert NR to NAD are up-regulated, which provides unique value over all other NAD precursors."

Charles Brenner, Ph.D.
Alfred E Mann Family Foundation Chair in Diabetes and Cancer Metabolism at City of Hope National Medical Center | Niagen Bioscience Chief Scientific Advisor

"With the clear preclinical benefits of NR observed in the brains of mice, I look forward to future clinical trial findings from testing in human subjects. In the meantime, the known ability of NR to enhance mitochondrial function and cellular energy makes it a top choice for my personal daily regimen."

Dr. Rudolph Tanzi
Kennedy Professor of Neurology, Harvard University | Director, Genetics and Aging Research Unit, Massachusetts General Hospital | Niagen Bioscience Scientific Advisory Board Member

"Tru Niagen stands out as the leading, gold-standard NAD+ supplement... crucial for maintaining cellular resilience, energy metabolism, and overall cellular repair. Further, it features patented nicotinamide riboside (NR), which is the most efficient NAD+ precursor available."

Dr. Jim LaValle
Clinical Pharmacist | CEO of Metabolic Code Enterprises | Former Niagen Bioscience Consultant
