TRU NIAGEN®'s active ingredient is nicotinamide riboside (NR), a unique molecule which has been scientifically researched to sustainably support NAD levels in all cells.

Why Your Body Needs NAD

NAD is an essential building block during energy production. But we lose up to 50% of our NAD levels between the ages of 40 and 60. When NAD levels are low, our cells can't produce the energy they need to maintain our health as we age. Here are some of the reasons why restoring NAD levels is a good idea.

  • Energy

    Every cell in your body needs NAD to turn food and drinks into energy.

  • Supports Muscle Recovery

    Muscle cells use NAD to recover from workouts.

What The Science Says

Scientists have known about the vital role of NAD since 1906. Since then, they’ve learned NAD is found in every living cell, and that it fuels the mitochondria, which keeps almost every tissue in the body healthy. In 2004, a landmark study by Dr. Charles Brenner uncovered a unique molecule called nicotinamide riboside (NR) that could sustainably support healthy NAD levels. Now with Dr. Brenner as our Chief Scientific Advisor, we’re bringing NIAGEN® to everyone.
4 Published Human Studies

All four peer-reviewed published human studies confirm NIAGEN® is a safe and efficient way of supporting NAD levels in humans.

100+ scientific Studies

Scientific studies at Dartmouth Medical School, University of Iowa, and École Polytechnique Fédérale de Lausanne lay the foundation for our human studies.

4 FDA Safety Reviews

NIAGEN® was twice successfully reviewed under FDA's new dietary ingredient (NDI) notification program, and also successfully notified to the FDA as generally recognized as safe (GRAS).

20 Licensed Patents

Our parent company, ChromaDex, holds a robust portfolio of domestic and international patents for both the production and distribution of NIAGEN®.

140+ Research Collaborations

NIAGEN® has been independently researched by teams at Cambridge University, Northwestern University, Duke University, New York University, University of California, and many more around the world to uncover the full potential of NAD to enhance human health.

What The Press Is Saying

"NAD+ is a molecule found in all living cells and is critical for regulating cellular aging and maintaining proper function of the whole body."

“Nicotinamide riboside is rare among supplement compounds in that it is being studied extensively, in trials funded by ChromaDex and other parties.”

“Another NAD+ booster, NR (nicotinamide riboside), found in ChromaDex’s Tru Niagen supplement can easily be purchased online, and has been shown to be safe in humans.”

What Tru Niagen® Is

TRU NIAGEN is a unique molecule called nicotinamide riboside (NR), which has been scientifically researched to sustainably support NAD levels.* We licensed the patents, supported the science, and manufacture our key ingredient NIAGEN® at cGMP facilities in the United States.

“The power of nicotinamide riboside (NR) to sustainably support NAD impressed me back in 2004 when I discovered it. Now, 14 years and 42 publications on NAD later, its unique ability to restore balance in the face of metabolic stress continues to amaze me.”
