Side effects, contraindications and regulatory status
Reported side effects
- Intravenous NAD+ 500 mg for 4 consecutive days (retrospective clinic records): moderate to severe gastrointestinal symptoms, increased heart rate and chest pressure during infusions; symptoms resolved when infusion ended; infusion averaged 97 min (Front Aging 2026).[3] C Observational
- Different substance, same study: intravenous nicotinamide riboside (NR) 500 mg for 4 days gave minor tongue, jaw and arm tingling and mild cramping; infusion averaged 37 min. NR is a precursor, not NAD+ (Front Aging 2026).[3] C Observational
- Systematic review (Ageing Res Rev 2026): no eligible outcomes trials evaluated intravenous or intramuscular NAD+ itself for anti-aging or wellness; one nonrandomized intravenous NMN study (a different substance) gave short-term safety data.[4] C Observational
- Same review: oral nicotinamide riboside and NMN (precursors, not NAD+, oral route) were generally well tolerated over weeks to months in human studies, per the authors.[4] C Observational
- Randomized trial of intravenous NAD+ 10 mg/day for 7 days vs placebo in 180 adults with ischemic cardiomyopathy heart failure: the abstract reports no adverse-event data (Am J Cardiovasc Drugs 2026).[2] B Human trial
Regulatory status
FDA 503A list (updated 2026-05-14): NAD in category 1 (under evaluation), as is NAD disodium reduced (NADH, a different form); beta-NAD disodium salt trihydrate in category 3. Checked 2026-10-20.[1] Source
