NAD+ precursor that supports cellular function, heart health and cognition

  • Nicotinamide riboside (NR) is a derivative of the B-vitamin niacin that supports health and longevity by serving as a precursor to NAD+.
  • NR supplementation has been found to improve various parameters of health, including cardiovascular health, cognition and neurological function, gene expression and healthy body weight.

Supports Cognition. Declining cognitive function with age is related to reduced NAD+ levels that impair mitochondrial function. Replenishing NAD+ stores through NR may be able to prevent this dysfunction. One study found that adults with a newly diagnosed neurodegenerative condition who took 1,000 mg NR for 30 days had increased cerebral NAD+ levels, mild clinical improvement and reduced activity of pro-inflammatory molecules in the cerebrospinal fluid. NR also increased the activity of genes involved with mitochondrial function and antioxidant responses. In animal and cell-based models, NR boosted brain NAD+ levels in mice, supported cognitive performance and behavior and slowed disease progression in several others. The mechanisms behind these benefits included reduced neuroinflammation, increased levels of BDNF (brain-derived neurotrophic factor) and elevated sirtuin activity. (1,2)

Supports Heart Health. Boosting NAD+ bioavailability with precursors like NR has been proposed as a strategy for supporting cardiovascular health in aging adults. Research showed that adults who took 1,000 mg of NR per day for six weeks had reduced blood pressure. Specifically, people with elevated blood pressure had a reduction in average systolic blood pressure (SBP) after taking NR compared to the placebo. NR had positive effects on risk factors for age-related cardiovascular events, such as aortic stiffness. (3)

Supports Metabolism and Healthy Weight. Although excessive body weight can develop at any age, adults over age 40 are particularly susceptible to age-related weight gain as metabolism slows down and body composition is altered to favor fat over lean muscle. As obese individuals have reductions in both NAD+ levels and ATP (energy) production, replenishing NAD+ through NR can help to reverse this while improving metabolic pathways to maintain a healthy weight. Research shows that supplementing with NR reduces fat mass and increases fat-free mass. (4)

  • Suggested Use: Take 1 capsule daily, with or without food, or as directed by your
    health care practitioner.
  • Note: Store in a cool dry place.
  • Caution: Not intended for use by pregnant or nursing women. Not formulated for use in children. If you have a medical condition or are taking medications, consult with your health care provider before using this product. KEEP OUT OF REACH OF CHILDREN.
  • Other Ingredients: Microcrystalline Cellulose, HPMC capsule.
  • Does Not Contain: Dairy, egg, soy, gluten, wheat, or artificial colors or flavors.
  • Nicotinamide riboside (NR) is a derivative of the B-vitamin niacin that can improve health and longevity by serving as a precursor to NAD+.
  • This formula also contains 150 mg of TMG (Trimethylglycine), an amino acid that supports the body's methylation processes.
  • NR supplementation has been found to improve various parameters of health, including cardiovascular health, cognition and neurological function, gene expression and healthy body weight.
  • ProHealth’s Nicotinamide Riboside Pro 300 utilizes a patented, clinically-researched form of NR called Niagen®.
  • Clinically-Proven NR. ProHealth Longevity’s NR uses a clinically-proven form of NR (Niagen®) to boost NAD+ levels.
  • Combines NR and TMG. When taken as a supplement, NAD+ boosters like NR may require the use of methyl groups to help facilitate the conversion of NAD+ in your cells. Although there is currently no evidence suggesting that NR’s natural methylation process depletes the methyl pool, many top anti-aging experts suggest that safeguarding against methyl depletion may be a wise proactive step to augment your NR intake. TMG, the choice of many of those experts, is an excellent way to help support your body's ability to maintain an adequate methyl pool.
  • Convenient Capsule Form. This NR comes in capsule form, making it easy and convenient to take NR while on the go or traveling.
  • Solvent-Free. Compared to other NR products, ours is made without any chemical solvents.
  • Quality Manufacturing Practices. All of our products are manufactured in an FDA-registered, GMP-certified facility.
  • Third-Party Tested in the USA. Every batch is third-party tested in US laboratories to ensure the highest quality, purity and potency. Certificates of Analysis are available.

The real deal!

I am extremely pleased with ProHealth's exceptional NR product, which undoubtedly stands as the finest in the market!

Wonderful New Product

I love ProHealth and happy to be try the new product. Great addition to my Trans Resveratrol and TMG!

Janis G.
Recommended by my doctor

I understand that this is the best NAD on the market and it is well priced.

Too Soon to Tell

I have only been taking this supplement for about a month and I have not noticed any major changes in how I feel. I think it's too soon to tell, but I will take it for another month to see what happens. It is not causing any unpleasant side effects.

Same Price but Better

ProHealth has a long reputation for having the highest quality and rigorous 3rd party lab testing of every product. I trust them generally, but this product specifically uses nicotinamide riboside from chromadex who owns the patents on the ingredient and manufactures it in the USA. They spent tens of millions on research and have the real NR instead of cheap NR from china. It's the real deal. and this one has TMG added which is critical for methyl replenishment if you take NR.

Nicotinamide Riboside

Great product, I feel more energy when I combine the usage with [N] [M] [N], trans resveratol, TMG and fish oil for absorption

Frequently asked questions

While results may vary based on a variety of factors, NR has been shown to significantly increase NAD+ levels in humans in as little as two weeks.
Research shows that increasing NAD+ levels in aged animals extends their lifespan, but we don’t know for sure if taking supplemental NR does the same in humans.
Clinical research conducted on humans taking NR shows no clinically relevant adverse effects at doses less than 2,000 mg per day.
Research suggests that taking NR may be more effective than taking NAD+ is more efficiently transported into the cell.
