Line chart showing that NAD+ levels in tissue decline by up to 65% between ages 30 and 70. The graph curves downward from age 30 to age 70, indicating a steady decrease. Text on the chart reads “NAD+ Decline ↓ 65%.” Source: Massudi et al., 2012; Janssens et al., 2022, based on analysis of human skin and muscle tissue.

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 and lifestyle 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 and Niagen Bioscience Scientific Advisory Board Chairman

"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, and former Niagen Bioscience Consultant

"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., ChromaDex’s Chief Scientific Advisor
Alfred E Mann Family Foundation Chair in Diabetes and Cancer Metabolism at City of Hope National Medical Center

"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

“I am 66 and my wife and I have taken Niagen for 10 years and are both physically in better shape now than when we started. We see many people our age who are starting to decline and feel that we are not seeing that in our own lives. The Niagen experiment is working for us and we have no plans of stopping.”
