NMN
The NAD+ precursor at the center of longevity research: 500 mg of high-purity NMN a day to support the coenzyme your cells use to make energy.
Topping up the fuel your cells run on
NAD+, nicotinamide adenine dinucleotide, is a coenzyme found in every cell. It is central to the reactions that turn food into usable energy inside the mitochondria, and to the housekeeping that keeps cells in good repair. The problem is that NAD+ levels fall steadily as we age, and researchers link that decline to the drop in energy and resilience that comes with the years. NMN is a direct precursor: the body converts it into NAD+. Human trials now show that oral NMN raises blood NAD+ in a dose-dependent way. This is one 500 mg capsule of 99.9% pure NMN, in the range used in that research.
Aerobic capacity, from the cell up
In a randomized, placebo-controlled trial, amateur runners who took NMN for six weeks improved their aerobic capacity more than placebo, an effect the researchers tied to better oxygen use by working muscles. NAD+ sits at the very center of how mitochondria produce energy, so keeping it topped up is a foundational, rather than flashy, support for endurance and recovery. It is not a stimulant. It works on the machinery underneath the effort.
Studied, not just marketed
NMN is one of the most actively studied compounds in longevity science, and the human trials are now arriving. Here is what they show.
Summaries describe published research on the ingredient, not on this specific product. Individual results vary.
Energy that is built, not borrowed
Caffeine borrows energy from later in the day. NAD+ support is about the underlying capacity to make energy in the first place. For people running hard careers into their forties, fifties and beyond, that is the appeal of NMN: it supports the coenzyme that cellular energy and repair depend on, and which quietly declines with the years. Treat it as a long-game habit, one capsule each morning, not a jolt you feel by lunchtime.
Why Dr. Elizabeth stocks this
"NMN is one of the few longevity compounds I stock, because it is one of the few with human trials, not just mouse data, showing it raises NAD+. I am honest with patients: this is early science, not a fountain of youth. What we can say is that NAD+ falls with age, that oral NMN raises it, and that the first controlled trials on energy and metabolism are encouraging. I recommend it as one part of a healthy-aging plan that still rests on sleep, movement and food, not as a replacement for them."
What to expect
Take one capsule in the morning with water. This is a foundational supplement, so you will not feel a caffeine-like hit, and that is exactly as expected.
NAD+ builds with consistent daily use. Any change in day-to-day energy and stamina tends to be gradual rather than sudden.*
NMN is a long-game, daily habit. The effects seen in research come from sustained use, alongside good sleep, regular exercise and a solid diet.
The details
Ingredients, suggested use & label facts
NMN Capsules provide 500 mg of ß-Nicotinamide Mononucleotide (purity 99.9%), a compound that plays a key role in the body’s natural production of NAD+ (nicotinamide adenine dinucleotide). NAD+ is involved in cellular energy metabolism and is essential for many biological processes. As NAD+ levels naturally decline with age, NMN supplementation has become increasingly popular among longevity and healthy aging enthusiasts. This formula offers a simple way to incorporate NMN into your daily wellness regimen.
Designed for high-performing professionals and proactive health consumers, NMN Capsules support cellular energy production to help maintain daily vitality. By promoting NAD+ biosynthesis, NMN helps support normal metabolic function and overall cellular health. This makes it a practical choice for individuals balancing demanding careers, active lifestyles, and long-term wellness goals. The capsule format ensures precise dosing and convenient daily use.
Research-oriented consumers interested in the science of healthy aging often look to NMN as part of a comprehensive approach to wellness. Our NMN Capsules are formulated with a single active ingredient—ß-Nicotinamide Mononucleotide—at 500 mg per serving, without unnecessary additives. When combined with a balanced diet, regular exercise, and healthy lifestyle habits, NMN supplementation can be a valuable addition to a proactive health strategy. Always consult a qualified healthcare professional before starting any dietary supplement.*

Good questions
What are NMN and NAD+?
NAD+ is a coenzyme in every cell that helps turn food into energy and run cellular repair. Its levels fall with age. NMN is a molecule your body converts directly into NAD+, which is why it is used to support NAD+ levels.
Will I feel it right away?
Probably not, and that is normal. NMN is not a stimulant. It works on the underlying machinery of cellular energy, so any benefits build gradually with daily use rather than arriving as a noticeable hit.
How much should I take and when?
One 500 mg capsule daily, in the morning, with water. That is within the range used in the human trials. There is no need to exceed it.
Is it safe? Who should avoid it?
NMN was well tolerated in the human trials to date, but it is still an emerging supplement and long-term data is limited. Do not use it if you are pregnant, nursing or under 18, and check with your physician first if you have a medical condition or take medication.
Is this a proven anti-aging pill?
No, and we will not pretend otherwise. What the research shows is that NMN raises NAD+ in people and that early trials on aerobic capacity and metabolism are promising. It is a supported part of a healthy-aging routine, not a cure for aging.
