FAQ

Yes, our capsules are intended to be taken indefinitely as a dietary supplement. Tru Niagen® is most effective when used daily over an extended time.

Tru Niagen 300mg is our original recommended serving and our first-ever product to launch. In 2019, we published a clinical study in Scientific Reports showing an NAD+ increase of about 50% in participants, with no adverse effects. We also gained United States FDA acceptance for Niagen (our patented form of nicotinamide riboside) as a New Dietary Ingredient at 300mg.
We’ve come a long way since launching in 2017, and so has the science. We now recommend 300mg of Tru Niagen as a daily minimum serving to maintain elevated NAD+ levels and sustain healthy-ageing benefits..

Tru Niagen® is for anyone over the age of 18. If you are pregnant, nursing, or taking other medications, please consult with your healthcare practitioner.

The cost of Tru Niagen® truly reflects our dedication to the quality of our product. We only use the finest ingredients and ensure efficacy and purity through a total of 22 internal and third-party quality control tests. 

Our price also reflects the considerable time and effort dedicated to progressing the science behind our product, putting Niagen® at the forefront of 30+ published clinical and 200+ preclinical studies. These studies help us fortify our existing science and explore additional benefits. 

The expiration date for your order is printed on the bottom of your bottle of Tru Niagen®. 

We’re excited you want to try Tru Niagen®!  The nature of our product recommends daily use up to and beyond eight weeks to experience the full benefits of increased NAD+*. Because of this time frame, we do not offer samples or trial size options for our product.

To date, there are no known contraindications for Niagen® nicotinamide riboside (NR), the key ingredient in Tru Niagen® products. But we always recommend checking with your healthcare practitioner if you are taking any medications.

No, Tru Niagen® does not need to be refrigerated. Tru Niagen is formulated with a crystalline form of nicotinamide riboside (NR) chloride, a shelf-stable ingredient when stored under the recommended conditions listed on the Tru Niagen bottle. Also, ChromaDex specifically formulates products with overall stability and quality in mind. All ChromaDex products undergo rigorous internal testing and development to ensure the bottle contains what is claimed on the Tru Niagen label.

For best results, store Tru Niagen® in a cool, dry place to help extend the product's life through the expiration date. But Tru Niagen will maintain its quality, safety, and potency during exposure to high temperatures (100-130 degrees Fahrenheit) for short periods, such as product shipment duration. 

Tru Niagen® contains a unique supernutrient known as nicotinamide riboside (NR). Our patented and FDA-notified product boosts NAD+, an essential molecule that is vital to the healthy functioning of your cells. Boosting your NAD+ with Tru Niagen supports muscle, brain, and heart^§health, cellular energy production and repair.

As with any supplement or new health routine, your experiences will vary depending on your age, diet, exercise, and sleep habits. Tru Niagen® increases NAD+ levels shortly after you begin taking it and maintains elevated NAD+ levels with daily supplementation. Everyone experiences different results based on their individual needs and lifestyle, but Tru Niagen is working at the cellular level—so even if you don’t necessarily feel anything, you can rest assured that it’s helping your cells stay energised and resilient in the face of everyday stressors.  

The active ingredient in Tru Niagen® is a supernutrient known as nicotinamide riboside (NR). It is structurally and functionally identical to naturally occurring nicotinamide riboside found in trace amounts in milk. Tru Niagen uses a patented form of this nature-identical ingredient to provide a more commercially viable and potent product.

There are no specific dietary restrictions to follow while supplementing with Tru Niagen®. Tru Niagen is formulated without nuts or gluten and does not contain caffeine, animal byproducts, or artificial colors or flavors.

The empty space in our capsules relates to the density of our active ingredient, nicotinamide riboside (NR). Our ingredient is more compact, which can give the appearance of an under-filled capsule. The capsules are filled by weight rather than by volume to ensure they meet our specifications for potency. Each Tru Niagen® capsule contains the precise milligram measurement of nicotinamide riboside stated on the product label and confirmed by testing.

While there are no published human studies examining the combined effect of consuming alcohol and Tru Niagen®, there is no specific reason to avoid taking Tru Niagen with alcohol. However, we still recommend that you speak to your healthcare practitioner before adding a new dietary supplement to your routine. 

Tru Niagen® is not known to negatively interact with other ingredients or products. However, we cannot account for the safety of outside ingredients. You should always follow the directions on the label and consult your healthcare practitioner with any questions.

Tru Niagen® has no known negative interactions with NSAIDs. If you have any questions or concerns, we recommend consulting your healthcare practitioner prior to use.

Though trace amounts of our key ingredient can be found in human breast milk, we do not yet have any research evaluating the safety of Tru Niagen® supplementation while breastfeeding. We recommend consulting your healthcare practitioner prior to use.

Tru Niagen® is not intended for use by children, although there is no specific reason that they should avoid Tru Niagen. However, more studies evaluating its safety in children are needed.

Tru Niagen® helps support cellular energy production by increasing NAD+ levels. NAD+ is a vital cellular resource that helps support cellular energy production (ATP). This energy powers everything our cells and bodies do and helps muscle function before, during, and after exercise. Cellular energy is needed for muscle contractions in the body and NAD+ helps support this process. NAD+ is also critical for cellular repair, including skeletal muscle repair.

Yes, not to worry! Tru Niagen® has been shown to be well tolerated up to 2,000 mg/day in human clinical studies, and many published human studies have been conducted using 1,000mg per day. Study participants did not experience any attributable adverse effects throughout any of these studies. Ultimately, how much Tru Niagen you choose to take comes down to what feels right for you and your body.

Absolutely not! Tru Niagen® products are always made and sold new regardless of where you purchase.
