NAD+ IV vs injection — what's the difference?
Both raise systemic NAD+. IV is faster and more concentrated; injection is more convenient and supports steady cadence. Oral precursors (NR, NMN) work indirectly through salvage pathways.
Full answer
NAD+ IV infusions deliver a high concentration of NAD+ directly into the bloodstream over 60-180 minutes, producing the fastest and largest serum NAD+ rise. NAD+ injections (subcutaneous or intramuscular) are more convenient, support a steady at-home cadence, and avoid the time investment of IV. Both raise systemic NAD+; oral precursors (NR, NMN) work indirectly through salvage pathways and raise NAD+ more modestly. The choice depends on goals, tolerability (IV NAD+ can produce intense transient sensations), schedule, and cost. Provider review individualizes the regimen.
