Buy NAD+ Online
NAD+ (Nicotinamide Adenine Dinucleotide) is an essential cellular coenzyme involved in energy production, DNA repair, redox reactions, and numerous metabolic processes. Interest in NAD+ has grown rapidly as researchers investigate its role in aging, mitochondrial function, metabolism, and cellular resilience.
Unlike the peptide products commonly featured on Purerawz, NAD+ is not a peptide. It is a naturally occurring pyridine nucleotide found throughout the body’s cells.
Product Information
NAD+ works as both a metabolic cofactor and a substrate for enzymes involved in energy metabolism, DNA repair, cellular signaling, and oxidative-stress responses. NAD+ levels can change with age and metabolic stress, which has led to extensive research into strategies for restoring or increasing cellular NAD+ availability.
Research has largely focused on NAD+ precursors such as nicotinamide riboside (NR) and NMN, while direct NAD+ administration is increasingly being explored in IV and other clinical settings. A 2026 systematic review concluded that NAD+ augmentation clearly produces biological activity, but evidence for meaningful anti-aging or wellness outcomes in humans remains inconclusive.
How Does NAD+ Work?
NAD+ participates in hundreds of enzymatic reactions, helping cells convert nutrients into usable energy while supporting DNA repair, mitochondrial metabolism, redox balance, and cellular signaling.
NAD+ Benefits
Supports Cellular Energy Production
NAD+ is central to mitochondrial energy metabolism and helps facilitate the reactions required to generate ATP. Maintaining adequate NAD+ availability is therefore a major focus of research into cellular energy and metabolic function.
Supports DNA Repair and Cellular Maintenance
NAD+ is consumed by enzymes involved in DNA repair and cellular stress responses, including PARP enzymes. This has made NAD+ an important research target in studies examining cellular aging and accumulated DNA damage.
Mitochondrial and Metabolic Research
Preclinical research has associated NAD+ restoration with improvements in mitochondrial function, metabolism, and resistance to cellular stress. Human studies, however, have produced more mixed results, particularly when looking beyond biochemical NAD+ changes to meaningful health outcomes.
Helps Healthy Aging
Declining NAD+ availability with age has become a major area of longevity research. Researchers are investigating whether restoring NAD+ availability can influence metabolic, mitochondrial, and cellular aging processes. Current evidence supports biological activity but does not yet establish NAD+ as a proven anti-aging intervention.
NAD+ Side Effects
IV NAD+ can produce noticeable infusion-related effects. Recent human data reported nausea, abdominal cramping, diarrhea, vomiting, increased heart rate, throat discomfort, congestion, and chest pressure, with symptoms resolving after the infusion. Community reports also commonly mention fatigue, nausea, and temporary discomfort during faster infusions.
NAD+ Dosage
Reported clinical protocols vary considerably. A human pharmacokinetic study administered 750 mg IV over six hours, while a newer real-world study used 500 mg IV daily for four consecutive days. Community protocols for subcutaneous NAD+ commonly report much smaller amounts, such as 25–100 mg per administration, while some users report 250 mg or more. These routes and doses should not be treated as interchangeable.
