      Supports cellular energy production by fueling mitochondria, your cells'energy engines.


      Boosts NAD+ levels essential for cellular repair and regenerationprocesses.


      Helps maintain cellular health as NAD+ naturally declines with age.

      Even at rest, the brain consumes around 20% of your body's energy tomaintain vital activities.


      Like all other vital organs, the specialized cells and tissues in your brainneed NAD+ for energy production and repair.


      Research has shown that NAD+ helps neurons adapt to physiologicalstressors and may help slow down the effects of brain aging.

      Muscle cells need a constant supply of ATP (adenosine triphosphate) forenergy. NAD+ is required to produce ATP.


      A clinical study shows that the effects of a sedentary lifestyle lead to lowerNAD+ levels, which can lead to more signs of aging.


      Movement and higher NAD+ levels help maintain muscle health as youage, reducing the physical hallmarks of aging.

      Strong cardiovascular health has lifelong importance. Taking care of yourheart starts early-with proper diet, exercise, and cellular support.


      Every cell in your heart needs NAD+ for energy production and cellularrepair. Tru Niagen is clinically proven to boost levels of this vital molecule.


      Studies suggest that increasing NAD+ levels with Tru Niagen, incombination with a healthy lifestyle, can support the aging heart.

      WHY TRU NIAGEN IS THE #1 NAD+ brandin the U.S.

      Superior absorption, provenresults, and greater valuethan the knock-off brands.

      Frequently Asked Questions

      What is NAD+ and how does it work?

      NAD+ (Nicotinamide Adenine Dinucleotide) is a crucial coenzyme found in everycell of your body that powers hundreds of metabolic processes. It serves as akey player in cellular energy production, DNA repair, and cellular communication.NAD+ works by transferring electrons during cellular metabolism, enabling yourcells to convert nutrients into energy and supporting essential functions thatkeep your body running optimally.

      What are the potential benefits of taking NAD+ supplements?

      NAD+ levels naturally decline from birth, accelerating around age 30, anddropping by up to 65% by age 70. Environmental and lifestyle stressors alsodiminish NAD+ levels, as do immune and health challenges. Taking a clinicallyproven supplement like Tru Niagen helps maintain your NAD+ baseline levelswith daily use-to keep your body running smoothly as you age.

      What is the difference between Tru Niagen and other NADbrands on the market?

      Tru Niagen is a superior choice compared to other NAD supplements because itcontains Niagen@, our patented nicotinamide riboside (NR), a more bioavailableprecursor to NAD+. NiagenR NR is backed by 35+ human clinical studies, andcrosses cell membranes easily and is more efficiently converted into NAD+inside cells, effectively boosting NAD+ levels.This enhances energy metabolism, supports cellular repair, and promoteshealthy aging, making Tru Niagen a more reliable, high-quality, pure, and potentoption for raising NAD+ compared to other supplements. Tru Niagen@ isclinically proven to increase NAD+ levels by over 50% with 300mg daily and byup to 150% with 1000mg daily and is backed by third-party quality-testing fromNSF Certified for Sport and Alkemist Labs.

      How quickly can I expect to see results from taking TruNiagen?

      Most people report noticing improvements in cellular energy and overallwellbeing within 2-4 weeks of consistent daily use. However, the cellular healthbenefits of increased NAD+ levels begin immediately, even before you feelnoticeable changes.Clinical studies show that Tru Niagen begins elevating NAD+ levels within hoursof taking your first dose, with significant increases observed within 2 weeks ofdaily supplementation. For optimal results, we recommend taking Tru Niagenconsistently as part of your daily routine.

      Is Tru Niagen safe, and are there any side effects?

      Tru Niagen has been rigorously tested for safety and is well-tolerated. Ourproprietary key ingredient NiagenR has successfully completed multiple FDAsafety reviews and is manufactured in cGMP-certified facilities in the USA.Niagen is supported by 35+ clinical studies demonstrating its safety andefficacy. These human studies form the foundation of our scientific evidence.Over 65% of registered ongoing or completed nicotinamide riboside trials useNiagen.2 Niagen is also backed by independent research, with over 90% ofNiagen studies being investigator-driven and third-party funded.In clinical studies, participants reported minimal to no side effects when takingthe recommended dosage up to 2,000mg per day. Some individuals mayexperience mild and temporary effects that typically resolve quickly. As with anysupplement, we recommend consulting with your healthcare provider beforestarting Tru Niagen, especially if you have existing health conditions or takemedications.
