Common side effects
2Injection site reactions (SC/IV)
Can be significant with IV; flushing and discomfort.
Flushing
Common with nicotinamide precursors.
Uncommon side effects
3Nausea
Particularly with high doses.
Headache
Reported in trials.
Fatigue
Paradoxical; reported in some users.
Rare side effects
1Liver enzyme elevation
High-dose nicotinamide can elevate liver enzymes.
Contraindications
- Known hypersensitivity
- Severe liver disease
- Pregnancy (precautionary)
Drug interactions
- Limited significant clinical interactions
- Nicotinamide at high doses may interact with chemotherapy agents
Special populations
Precursors (NR, NMN) have favorable safety in elderly trials. IV NAD+ less well-characterized.
Overall safety summary
NAD+ precursors have a favorable safety profile in pilot studies. IV NAD+ infusions can cause more substantial transient side effects (flushing, nausea) during administration but resolve upon completion.
NAD+ side effects: FAQ
Is IV NAD+ safe?
Short-term IV NAD+ appears safe in pilot studies. Infusions can cause uncomfortable side effects (flushing, nausea) during administration. Long-term safety is not well established.
