"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."

"NAD is vital to how cells use energy, a key player in metabolism."

"Levels of NAD decline with age, and fasting is one way to replenish them; NR supplements is another."

All of your cells need NAD to function

NAD declines up to 50% between ages 40-60

"The power of this form of vitamin B3 to raise 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.”

—Dr. Charles Brenner, Ph.D., Discoverer of NR as a vitamin

The Real Deal!
I am a scientist and am naturally skeptical of most supplements, which have little evidence to back up their claims. Niagen is the oppositeover the past few years, there has been a parade of high-profile studies in top scientific journals demonstrating that supplementation with nicotinamide riboside (NR; a.k.a. niagen) is hugely beneficial for cells. NR is a precursor for NAD+, which is an ancient molecule that has been conserved by evolution and is required for essential cellular activities such as mitochondrial biogenesis / function. NAD+ levels decline with age, and so do mitochondrial biogenesis. I am 43 years old and have been taking Niagen for ~2 yrs. I feel better than I have in a while. I attribute this to Niagen and recommend it to anyone in middle age or beyond.

Excellent Product
Tru Niagen exceeded my expectations! Within a few days of starting to take it, I noticed a definite improvement in my energy levels and general well being. I'm not going to stop taking it.

Good Addition to My Health Regimen
Since adding Tru Niagen to my regular health routine, I’ve experienced increased energy, more stamina during physical exercise, and improved sleep. It’s not that I sleep longer, but I wake up more renewed. In terms of energy, it clearly affords a boost, but not in the way one experiences with energy drinks or too much caffeine, which leave me wired. Good stuff.

How Can You Change The Way You Age? The Answer is NAD.

Raise Energy Levels

As we age, our cells become less efficient and produce less energy from the foods and beverages we consume. Niagen delivers a sustained, smooth boost of energy throughout the day by recharging your body's cells.

Increase Metabolism

Your metabolism is the cellular process of breaking down food into energy. As we age, our metabolism slows down, leading our bodies to store fat instead of burning it. By boosting NAD, your mitochondria finally have the fuel they need to start using energy and fat more efficiently.

Sleep Better

Energy metabolism, hormone regulation, body temperature variations all rely on a 24-hour cycle as well. NAD helps regulate circadian rhythms, keeping them all in sync and working at their best.

Faster Muscle Recovery

Niagen has powerful anti-inflammatory properties that can soothe inflamed, aching joints and muscles. Boosting NAD levels across the body delivers a vital recharge to all of your mitochondria. By making your mitochondria more active and more efficient, it is possible to drastically reduce inflammation around the body.

What's in Tru Niagen®?

One capsule of Tru Niagen® contains 150mg of our active ingredient Niagen®, a patented and FDA safety-notified form of vitamin B3. Our inactive ingredients are microcrystalline cellulose and hypromellose. Microcrystalline cellulose is a plant-derived fiber and hypromellose is a common ingredient used to make vegetarian capsules. Tru Niagen® contains no nuts, no caffeine, no gluten, and no artificial colors or flavors. 

What Should I Expect To Feel?

Tru Niagen® will start increasing NAD levels shortly after you take it and will continue to maintain those elevated NAD levels with regular supplementation. As with any supplement or new health routine, your experiences will vary depending on your age, diet, exercise, and sleep habits. It may take some time to feel the benefits of increased NAD (promoting cellular repair, increasing cellular energy, etc.), but ultimately Tru Niagen® is helping your cells remain energized and resilient in the face of everyday stresses.*

What People Think About Tru Niagen®

What People Think About TRU NIAGEN®

NAD Produces Energy

Every cell in your body uses NAD to convert food into energy

Improved Heart Health

Heart cells use NAD to help pump blood throughout the day

Better Sleep

All of your cells rely on NAD to keep circadian rhythms in sync

Faster Muscle Recovery

Muscle cells use NAD to recover from workouts

NAD Completes Your Cellular Circuits

We eat to nourish and energize our bodies. You can think of food as a source of energy, much like a battery. A battery won't power a lightbulb unless it's connected with the right wires and circuits. And cells can't do anything with the energy stored in that food unless they have the right molecules. One of these molecules is NAD.

NAD acts like the wires connecting a battery to a lightbulb—without NAD available to convert food energy into cellular energy, cells would be left in the dark.
