How can you increase your NAD+ levels? NR900 is the evidence-based choice
We now have a way to safely and sustainably boost levels of NAD+. Developed by Dr. Leonard Guarente, a leader in the field of aging research, NR900 was clinically proven to increase NAD+ levels by an average of 40% in a double-blind, randomized, placebo-controlled clinical trial published in the peer-reviewed journal Nature Partner Journals: Aging and Mechanisms of Disease.

Frequently Asked Questions
Why are sirtuins important for aging?
Sirtuins are a family of proteins that regulate cellular health. Sirtuins play a key role in regulating cellular homeostasis. Homeostasis involves keeping the cell in balance. However, sirtuins can only function in the presence of NAD+, nicotinamide adenine dinucleotide, a coenzyme found in all living cells.
What is Nicotinamide Adenine Dinucleotide (NAD+) and why is it important?
NAD+, or nicotinamide adenine dinucleotide, is a critical coenzyme found in every cell in your body, and it’s involved in hundreds of metabolic processes — but NAD+ levels decline with age. NAD+ has two general sets of reactions in the human body: Helping turn nutrients into cellular energy as a key player in metabolism and working as a helper molecule for proteins that regulate other cellular functions. These processes are incredibly important.
What is Nicotinamide Riboside (NR) and why is it important?
This form of Vitamin B could be the key to increasing NAD+ levels — here’s why. Nicotinamide riboside is often called NR for short, and it’s a precursor to NAD+, meaning it's the raw material from which your body makes NAD+ through a series of chemical transformations. Human clinical studies, including ours, have shown efficacy of NR supplementation in increasing NAD+ levels.
What is Pterostilbene and why is it important?
Pterostilbene is a polyphenol, a type of molecule that occurs in plants, particularly small berries and nuts. Blueberries are a particularly rich source of pterostilbene; although it is found in grapes, pterostilbene (unlike its cousin resveratrol) doesn’t survive the wine-making process.
What are the results of your clinical trial?
It conducted a first-in-humans study demonstrating clearly that NR900 can increase and sustain cellular NAD+ levels. Participants in the trial experienced a 40% average increase in cellular NAD+ levels within a month, which was maintained for the duration of the trial. We also tested a variety of biological markers to add to the existing body of evidence confirming that the ingredients in NR900 are safe.
