NAD+ IV vs oral — which is right for me?

Short answer

IV NAD+ delivers full-dose loading; oral and intranasal precursors (NR, NMN) support steady-state maintenance. Many candidates combine an IV loading phase with oral/intranasal maintenance under provider review.

Full answer

IV NAD+ delivers NAD+ directly and is often used for loading and acute reset; the experience can be intense and is dose- and rate-dependent. Oral NAD+ precursors (nicotinamide riboside, nicotinamide mononucleotide) support steady-state NAD+ over time with high patient convenience. Intranasal NAD+ offers rapid mucosal absorption with moderate convenience. Many candidates combine an IV loading phase with oral/intranasal maintenance. The selection is driven by goals, tolerability, time, and budget, under synchronous provider video review.

Educational. Not a substitute for individualized provider review.
