Tru Niagen 100mg

$19.97
    • Supports heart§, brain, muscle, immune (with TruNiagen Immune) health, cellular energy production and repair, and lifestyle stress management. Clinically proven to boost nicotinamide adenine dinucleotide (NAD+), which is vital to life as we know it.*

    • The key active ingredient in Tru Niagen is Niagen®, our patented, safety-reviewed form of nicotinamide riboside (NR), a precursor to NAD+. Niagen was designed to easily pass through your cell walls and facilitateNAD+ production more efficiently than other NAD+ supplements or precursors.  

    • Vegetarian capsules are formulated without gluten or nuts, and do not contain caffeine, animal byproducts, artificial flavors or colors. See nutrition facts on label for more information. 

    • Niagen is FDA notified (at 300mg) as GRAS (Generally Recognized as Safe) and successfully notified to the FDA as a New Dietary Ingredient.  

    • NSF Certified for Sport®—this certification means that Tru Niagen is made to current Good Manufacturing Practice (cGMP) standards, tested to confirm the level of Niagen in the product, and to confirm the absence of over 270 athletic banned substances and harmful contaminants. Approved for sale globally in Canada, the EU, Australia, New Zealand, and Brazil.

    • Tru Niagen is meant to be taken daily to support increased NAD+ levels. Feel free to start at just 100mg and add more as you get comfortable. You might stick with that amount, or you might feel best taking 300mg (our recommended baseline serving), or you might want to take even more. Studies have shown a more pronounced boost in NAD+ levels from taking as much as 1,000mg daily, and Tru Niagen is safe to consume up to 2,000mg per day. 

    • If you’re already taking Tru Niagen, 100mg capsules are a great way to optimize your NAD-boosting regimen and stack little by little to see if anything changes by taking extra Niagen. Please note that everyone’s experience will be different and is greatly dependent on your overall health and other factors. 

Start Slow, or Push Your Limits

Tru Niagen 100mg serves two needs. If you’re new to Tru Niagen, this is an introductory serving size that allows you to ease into using the product and see how it works for you.

If you’re already reaping the benefits of taking Tru Niagen, 100mg capsules are a great way to optimize your NAD-boosting regimen and stack little by little to see if anything changes by taking more than the recommended serving.

The more you take, the more pronounced of a boost in your NAD+ levels, and taking more over time means you’ll sustain higher NAD+ levels, too.

WHY SHOULD YOU TAKE MORE TRU NIAGEN?

REASON #1

Your Body Needs Extra NAD+ in Times of Stress

In times of physiological stress—such as lack of sleep, excess sun exposure, overeating/drinking—your body needs more NAD+ to perform the same functions that might require less under more ideal circumstances. And did you know that your NAD+ levels can drop by up to 80% when you’re dealing with immune health challenges? That’s why it can be a good idea to take two or three capsules on days when you’re feeling depleted.

Your Body Needs Extra NAD+ in Times of Stress

REASON #2

Studies Show Positive Results from Extra Niagen

Taking more Tru Niagen daily can increase your NAD+ levels more substantially and more quickly. So even if you’re not facing major physiological stressors, you can still benefit from taking extra Niagen. Try adding additional 100mg capsules and see how you feel. It’s safe to consume up to 2,000mg per day.

As with any supplement or new health routine, your experiences will vary depending on your age, diet, exercise, and sleep habits. Tru Niagen® will start increasing NAD levels shortly after you take it and will continue to maintain those elevated NAD levels with regular supplementation. 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.*

The B3 vitamins have one thing in common: they are all building blocks cells can use to make more NAD. Nicotinic acid, nicotinamide, and nicotinamide riboside can all be turned into NAD, but cells use different recipes that require different amounts of energy and numbers of steps to make NAD out of each B3. Some B3s also come with some unwelcome side effects: nicotinic acid can cause an uncomfortable flushing response while nicotinamide can inhibit the activity of cellular health-promoting sirtuins.

We’ve written an entire post about the differences between NR and the other B3 vitamins, you can read it here.


Tru Niagen® increases levels of a key cellular resource known as NAD. Nicotinamide adenine dinucleotide (or NAD) is found in every living cell and is essential to a healthy cellular metabolism. While NAD is produced during energy generation, it’s also constantly being consumed. We use NAD whenever we eat, drink, sleep, or breathe. Studies also show our NAD levels decline as we age by as much as 50% between the ages of 40–60. Because NAD is essential to energy generation, the less we have of it, the harder it is for our cells to stay healthy as we age.

In 2004, Dr. Charles Brenner discovered that a unique form of vitamin B3 (nicotinamide riboside, or NR) was also an NAD precursor. Since then, multiple human clinical trials have shown NR safely and effectively increases NAD.

Tru Niagen® contains the patented and only known FDA-safety notified form of nicotinamide riboside, delivered straight to your door.
