Nicotinamide adenine dinucleotide (NAD+) is a coenzyme involved in cellular processes. It is not a peptide. Its role in cells does not establish that an infusion reverses aging, improves cognition or produces better energy or recovery in people.
Claims about a specific NAD+ preparation require human evidence for that exact formulation, route and intended use. Compounded NAD+ injections are not FDA-approved, and FDA does not review their safety, effectiveness or quality before marketing. This page is educational and does not offer an NAD+ product for purchase or prescription.
FDA has warned about food-grade NAD+ being used to compound intravenous products. Food-grade ingredients are not suitable for sterile compounding without appropriate processing. Reported reactions following NAD+ injections include severe chills, shaking, vomiting and fatigue, with some requiring medical treatment. These reports are consistent with excessive endotoxin exposure.
Discuss the reason for any proposed infusion, the dispensing source, ingredient suitability, sterility controls, alternatives and possible adverse effects with an appropriately licensed clinician. Persistent fatigue, memory changes or other symptoms deserve assessment rather than a promised anti-aging solution.
