What NAD+ is
Nicotinamide adenine dinucleotide participates in cellular energy and redox reactions. That biological role does not by itself prove that intravenous supplementation improves a particular symptom or outcome.
Clinical context matters
Evidence varies by proposed use, and marketing claims may extend beyond what controlled human studies establish. Decisions should consider alternatives, uncertainty, tolerability, and monitoring.
Evaluation before treatment
If offered, dosing and infusion rate are individualized. Public self-scheduling is not available and no therapy is promised before assessment.
