While many factors contribute to aging, scientists believe one primary reason is the depletion of a key cellular resource called NAD. Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in every living cell and is as essential to those cells as water is to the body. But as we age, NAD levels decline. This natural decline may speed up anytime we eat too much, drink too much, work too much, stay in the sun for too long, don’t sleep well, or get sick.

Because NAD is essential to healthy cellular metabolism, the less we have of it, the harder it is for our cells to stay healthy as we age. But higher NAD levels have been linked to all kinds of positive health benefits.

In 2004, Charles Brenner PhD discovered a unique molecule called nicotinamide riboside (NR) which is a natural precursor to NAD. Meaning it helps our cells create more NAD and thereby supports their healthy function.

NIAGEN® is the first and only patented and quality tested form of nicotinamide riboside, and is shown to support healthy NAD levels.

Take one capsule of TRU NIAGEN® (150mg) every day with or without food.

Nicotinamide riboside and nicotine both contain nitrogen, but are otherwise completely unrelated. The two compounds do not share any physiological properties in the body. 

Our vegetarian capsule is made of an FDA-approved food additive known as hypromellose. Hypromellose is a clear, transparent vegetarian alternative to gelatin capsules. [Note 21CFR 172.874]

TRU NIAGEN’s sole active ingredient, NIAGEN, is shown to support healthy NAD levels in humans. Healthy NAD levels are linked to all kinds of positive benefits.

Some of them include:

  • Supporting the maintenance of healthy cholesterol levels
  • Supporting normal cellular metabolism and energy production
  • Supporting liver function, especially after stress

Your experience will vary depending on what your cellular needs are. But the science shows that TRU NIAGEN® is hard at work on a cellular level. And the longer you take it, the more opportunities you’ll have to feel those changes.

Depending on your location TRU NIAGEN® does not normally need to be refrigerated. That’s because TRU NIAGEN® is formulated with a crystalline form of nicotinamide riboside chloride. This crystalline form is shelf stable when stored under the recommended conditions listed on the TRU NIAGEN® bottle. ChromaDex specifically formulates TRU NIAGEN® to enhance the overall stability and quality.


For long term storage, or if you live in an area with regular high temperatures, then refrigeration will ensure maximum shelf life.

Nicotinamide riboside was first identified in the 1940s.

Since that time, the role of nicotinamide riboside as a precursor to an essential coenzyme called NAD has been widely studied in the scientific community and become better understood. More than a decade of research has been conducted on nicotinamide riboside producing hundreds of research studies including a scientific study showing NIAGEN® supports healthy NAD levels in humans. These positive results have inspired research around the world. There are at least 14 additional human studies underway exploring the potential health benefits of NIAGEN®, the key ingredient in TRU NIAGEN®.

Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in every living cell. It’s essential to every cell but especially to those with mitochondria. That’s because the mitochondria are “the powerhouse of the cell.” Meaning that like any other battery or energy resource, the mitochondria depend on an external power source to keep them charged. NAD is that source.

With healthy NAD levels, our cells can function at their best and so we can too.

NIAGEN® is the first and only patented and safety-validated form of a unique and naturally occurring molecule known as nicotinamide riboside. TRU NIAGEN® is the name of our product. Each capsule of TRU NIAGEN® contains 150mg of NIAGEN®.

Based on published research results, we have no reason to believe TRU NIAGEN® will decrease the natural activity level of enzymes that make NAD.

TRU NIAGEN® is vegetarian, gluten-free, nut-free, caffeine-free, contains no animal byproducts, and no artificial colors or flavors.

Yes, TRU NIAGEN® can be taken with alcohol. NIAGEN® supplementation may be helpful in supporting a healthy liver.

Yes, you can take TRU NIAGEN® while taking a standard multivitamin that provides the daily recommended amounts of vitamins, including those with vitamin B3. TRU NIAGEN® contains nicotinamide riboside which is not the same as the vitamin B3 sources found in multivitamin products. TRU NIAGEN® is absorbed by cells and efficiently converted to NAD using a unique pathway different from vitamin B3 (niacin, nicotinamide) found in vitamin supplements. TRU NIAGEN® has been scientifically researched to sustainably support NAD levels.

Multivitamins are designed to provide the daily recommended values for essential vitamins and minerals and are appropriately balanced.

TRU NIAGEN® is not intended for use by children. We recommend pregnant or nursing women to consult a physician.

TRU NIAGEN® is manufactured in the U.S. under cGMP (current Good Manufacturing Practice) regulations enforced by the FDA. Our manufacturer is certified by the NSF, a leading independent public health and safety and each lot of TRU NIAGEN® undergoes thorough purity testing.

No known adverse effects attributed to the consumption of NIAGEN® were reported during the scientific studies. As with any form of supplementation, if you experience any prolonged discomfort or side effects, discontinue use and consult your healthcare provider.
