NAD+ plays a role in cellular metabolism, but its biological role does not prove that an IV infusion improves energy, memory, or longevity. Patients comparing NAD IV services in Los Angeles should understand both the limits of the evidence and the practical safety questions.
What research has measured
A 2019 pilot study examined NAD+ and related metabolites during an infusion. It was not proof of sustained improvement in fatigue, cognition, aging, or addiction outcomes.
A 2026 retrospective pilot study compared NAD+ and nicotinamide riboside infusions using tolerability and short-term clinical measures. A retrospective study of clients receiving treatment cannot, on its own, establish broad effectiveness or long-term safety. Researchers cannot treat evidence for NAD+, oral precursors, and different injection formulations as interchangeable.
Claims removed from this article
The earlier version suggested that IV delivery guarantees greater efficacy than oral products and promised sustained energy, mental clarity, and rejuvenation. It also described addiction-recovery benefits without sufficient supporting evidence. We have removed those claims. An NAD infusion should not replace established treatment for substance-use disorders or an assessment of withdrawal risk.
Compounding and infusion safety matter
FDA has reported adverse events after NAD+ injections, including severe chills, shaking, vomiting, and fatigue; some patients required medical treatment. The agency warned about unsuitable ingredients and endotoxin concerns in sterile compounding. This warning does not mean every preparation is contaminated, but it makes sourcing and preparation important questions.
Before paying for a course of infusions
- First, ask what specific outcome the clinician expects and what human evidence supports it.
- Also, ask who prescribes and administers the product and where it comes from.
- Next, ask how staff identify and manage adverse reactions.
- Finally, review the total cost, alternatives, and when the clinician would reassess treatment.
Persistent fatigue or brain fog deserves a medical history and assessment rather than an automatic infusion recommendation. Book a consultation to discuss symptoms and appropriate next steps. This page does not recommend a dose or infusion schedule.
