NAD+

Buy NAD+ Online

NAD+ is a naturally occurring cellular coenzyme central to energy production, redox balance, DNA repair, and mitochondrial function. It has become a major area of metabolic and healthy-aging research.

Product Information

Nicotinamide adenine dinucleotide is present in virtually every cell and participates in numerous enzymatic reactions. Research has investigated both NAD+ itself and compounds that increase cellular NAD+ availability.

How It Works

NAD+ acts as a key electron carrier in cellular metabolism and also serves as a substrate for enzymes involved in processes such as DNA repair and cellular signaling. Maintaining NAD+ availability is therefore closely connected with mitochondrial and metabolic function.

POTENTIAL BENEFITS

1. Cellular Energy Research

NAD+ plays a fundamental role in converting nutrients into usable cellular energy, making it central to metabolic and mitochondrial research.

2. Mitochondrial Function

Because mitochondria rely heavily on NAD+-dependent reactions, NAD+ has become an important target in research examining cellular energy and aging.

3. Healthy-Aging Research

NAD+ metabolism changes with age, leading researchers to investigate whether maintaining NAD+ availability could support healthier cellular function.

4. DNA-Repair Research

NAD+ is required by several enzymes involved in cellular stress responses and DNA repair, giving it importance in longevity and cellular-maintenance research.

5. Metabolic Research

NAD+ participates in glucose, fatty-acid, and overall energy metabolism, making it relevant across metabolic research fields.

Dosage

There is no universally established NAD+ supplementation regimen. A recent human trial investigated 10 mg/day intravenous NAD+ for seven days, while a 2026 real-world study reported commercial IV administration of 500 mg/day for four consecutive days. Online communities report substantially different protocols, highlighting the lack of standardization.

Side Effects

Recent real-world IV research reported gastrointestinal symptoms, increased heart rate, and chest pressure during NAD+ infusions. Symptoms resolved after the infusions ended.
