Typically prepared by a compounding pharmacy under the direction of a licensed healthcare professional — not an FDA-approved finished product in this form.
Overview
Product & regulatory status
Direct NAD+ infusion has not been established by these studies as an anti-aging, cognitive, or addiction treatment.
Energy and metabolism
NAD+ participates in cellular oxidation-reduction reactions. That biological role provides a research rationale, but does not by itself demonstrate benefits from adding more NAD+. [1]
What the evidence shows
What the human pilot measured
A 2019 pilot followed NAD+ and related metabolites in blood and urine during a six-hour intravenous infusion. Its purpose was to characterize metabolism, rather than demonstrate improved memory, recovery, or lifespan. [1]
A biomarker is not a benefit
Changes in circulating metabolites show that the administered substance is being processed. They do not show that brain NAD+ increased or that patients experienced meaningful clinical improvement. [1]
What remains unknown
Durable benefits, optimal clinical indications, and comparisons with oral precursors remain unresolved by this pilot.
Safety
Product quality matters
FDA received reports of severe chills, shaking, vomiting, and fatigue after NAD+ injectable products. The agency linked the concern to ingredients unsuitable for sterile compounding and reactions consistent with excessive endotoxins. [2]
Food grade versus injectable
An ingredient suitable for food is not automatically suitable for an injectable product. Appearance alone cannot confirm sterility or endotoxin safety. [2]
Understanding product quality
Compounded drugs are not FDA-approved finished products. Poor preparation can cause contamination or incorrect strength. A catalog entry or a research paper is not a quality assessment of your product. [3]
When to seek urgent help
Severe allergic symptoms such as trouble breathing, throat or tongue swelling, or fainting need immediate help. Call 911 or your local emergency number. This is general emergency information, not a complete list of risks for this compound. [4]
A starting point for discussion
This is not a complete list of adverse effects or interactions. Your health history, other medicines, and the exact formulation matter. Missing safety data is not evidence of safety.
Common questions
Is an NAD+ infusion the same as taking NR or NMN?
No. They are different substances and routes. Findings from an oral precursor trial cannot be transferred to an NAD+ infusion.
Questions for your clinician
Does the evidence match my condition and this exact product? What risks or interactions matter for me? How would we assess whether it is helping?
