NAD+ Therapy and Anti-Aging: What We Know, What We Don't, and Honest Expectations
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell. It is central to energy metabolism and to several pathways involved in DNA repair and cellular stress response. Cellular NAD+ levels decline with age. The wellness industry has built a large story from these facts. Some of that story has reasonable mechanistic support, and some of it does not.
What current evidence supports
Reasonable laboratory and animal data show that boosting NAD+ levels improves measures of mitochondrial function and certain markers of cellular stress. Small human studies suggest some patients experience subjective improvements in energy or mood. The evidence base for systemic anti-aging effects, lifespan extension, or treatment of specific diseases is much thinner. These benefits are frequently overstated in marketing materials.
| Claim | Evidence status |
|---|---|
| Mitochondrial function and cellular-stress markers | Supported by laboratory and animal data |
| Energy or mood | Small human studies suggest subjective improvement for some patients |
| Anti-aging, lifespan extension, or disease treatment | Evidence is much thinner and is frequently overstated in marketing |
What patients typically experience
NAD+ infusions are generally given slowly, often over two to four hours. This is because rapid infusion produces significant chest tightness, abdominal cramping, and a sensation many patients describe as unpleasant. Most people who tolerate the session well report a few days of improved energy and mental clarity. From a clinical standpoint, it is honestly unclear whether the molecule or the rest causes this.
Who should not consider NAD+
Patients with active cancer should not pursue NAD+ infusion outside of an oncologist's specific guidance. The same pathways NAD+ supports in healthy cells are exploited by some tumors. People with certain cardiac arrhythmias, severe kidney disease, or active infections should also defer. A physician-led screening conversation is non-negotiable for this particular therapy.
Honest framing
You may have a positive experience if you go into NAD+ infusion expecting to feel sharper for a few days. Treat it as one tool among many, including sleep, training, nutrition, and stress management. If you go in expecting it to reverse aging, you will be disappointed and will have spent a lot of money. We discuss this directly with every patient who asks about it.
