Key item features

  • What is NAD+? – Nicotinamide adenine dinucleotide (or “NAD+” for short) is a coenzyme found in every cell. NAD+ is essential for energy production, but NAD+ levels decline over time. Our formula delivers nicotinamide riboside to support healthy levels of NAD+.
  • Cellular Energy – NAD+ helps produce adenosine triphosphate, or ATP. You might remember ATP from grade school science class: it’s the compound your cells use to power their day-to-day processes. So supporting NAD+ levels supports cellular energy production.
  • Clinically studied – Nicotinamide riboside (or “NR” for short) is the best-studied of all the “NAD+ supplements.” It’s generally considered better than NMN (nicotinamide mononucleotide). Nicotinamide riboside has been shown to raise NAD+ levels in the blood.
  • Ingredients matter – We use only pure, high-quality ingredients. The majority of our products are non-GMO and gluten-free—and a Certificate of Analysis is available for every one.
  • Live your healthiest life - For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. That’s why so many of our nutritional formulas are designed using specific ingredients and amounts based on scientific studies.

Easy to swallow and digest.

I am very pleased with this supplement, It seems to be helping my body keep working to its potential. When I am at my Doctors they do ask what I am taking and when I mention this supplement they are pleased to hear me mention it.

Noticeable level of energy improvement

Have been taking for 1 month and used to have 1g of NMN daily before the FDA made it impossible to ride it seems. This is a great product but still looking at dosage for best results as studies conducted have generally been a bit more.
