Reverse the Signs of Aging with NAD+ — Backed by Cutting-Edge Research
NAD+ is a molecule found in all living cells and is critical for regulating cellular aging and maintaining proper function of the whole body. Levels of NAD+ in people and animals diminish significantly over time, and researchers have found that re-upping NAD+ in older mice causes them to look and act younger, as well as live longer than expected. In a March 2017 study published in the journal. Science, researchers at Harvard put drops of a compound known to raise levels of NAD+ into the water for a group of mice.... In about a week, signs of aging in the tissue and muscles of the older mice reversed...researchers could no longer tell the difference between the tissues of a 2-year-old mouse and those of a 4 month-old one. To date there is not yet evidence that this study can be. extrapolated to humans.

“I believe NR900 is a product that can improve Your cellular health and target, at least, some of the deficits incurred by aging. It is an important part of a strategy that I follow, along with exercise and a healthy diet, to maintain an active life as I enter my seventies, and hopefully much longer.”

How can you increase your NAD+ levels? NR900 is the evidence-based choice
We now have a way to safely and sustainably boost NAD+ levels. 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.
Boosted NAD+ activates sirtuins, supports cellular energy and metabolism, targets cellular aging to promote a healthy cellular aging process, and helps maintain healthy DNA.

The Most Advanced NAD+ Formula on the Market: Why We Stand Out
NR900 is clinically proven to safely and sustainably increase NAD+ by an average of 40% in humans. Aresify’s toxicology study also confirmed the superiority of the NR-E in NR900 when compared to the published safety profiles of other NAD+ supplements, underscoring the company’s rigorous commitment to research and quality.
The synergistic combination of Aresify’s proprietary and high-purity nicotinamide riboside (NR-E) with potent antioxidant pterostilbene (PT) makes NR900 extraordinarily effective. NR900 is also third-party tested by independent labs both during and after manufacture for purity and quality, and is independently verified as NSF Certified for Sport.

Live your best life with healthy cells
INTRODUCING NR900
NR900 is based on 30 years of research. Combat aging at the deepest level with NR900:
NAD⁺ not only helps convert food to energy but also plays a crucial role in maintaining DNA integrity and ensures proper cell function to protect our bodies from aging and disease.
✔️ Raise NAD+ levels by 40%

✔️ Help maintain healthy DNA.
✔️ Backed by a human clinical trial.
✔️ Reduce general tiredness and fatigue and support workout recovery
What to expect?
After a few days:
Your body will begin to adjust to a higher level of NAD+. Temporary leg cramps or headaches are common side effects.
After a few weeks:
Your cellular makeup
is replenishing through
the consistent increase
in NAD+, paving the way
to overall energy increase.
After a few months:
You may reach a new, elevated baseline of NAD+, supporting lasting improvements in energy levels, cell regeneration, cognition and skin health

Frequently Asked Questions
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.
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.
