Why NAD+ is the Key to Staying Youthful
Research published in Nature Aging “suggests that a clear association exists between NAD+ and health status in human aging.” NAD+ (nicotinamide adenine dinucleotide) is found in every cell in your body. It is essential to the chemistry that keeps you up and running.
Unfortunately, NAD+ levels decline universally as we age.
By replenishing your NAD+ levels, you can:
Feel more energized throughout the day
Combat aging at the cellular level
Improve mental clarity and focus

Marta S. July 2025Verified BuyerHighly recommended!I am an 81 year old woman who has been taking NR900 for a few years now and am convinced that it has helped to elongate my life expectancy. I've been reporting taking this product to all my doctors. I don't really understand the science behind NR900, but I appreciate what it does. Thank you very much for creating this product. It's priceless

Allysa L. July 2025Verified BuyerNice ProductI have been taking this NAD+ for over five months and I believe it has slowed down my aging. NR900 does not cure any issues, but at over 70 I work and play like 45.

Nicholas P. June 2025Verified BuyerThe best quality products available in one easy packageAfter extensively reading and researching various longevity products it was hard to find the recommended individual supplements from a reliable and tested source. Then we found Reus Research. Their products really do encapsulate - pun intended - all of the best supplements into one tried and tested package. We (my wife and I) have been taking them for ~90 days so far and we could not be happier with the way we feel. Reus Research makes the process of sourcing the best quality ingredients at a moderate dosage level very easy. This is exactly what we were looking for. Thank you Reus Research!!!

FAQs
Reus Research Q&A
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?
his 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 are the results of your clinical trial?
It conducted a first-in-humans study demonstrating clearly that Resu Research 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.
