Delivery method
IV Drip
Direct NAD+ infusion typically delivered in supervised settings.
Slow intravenous infusion (typically 250-1,000 mg over 2-4 hours) bypasses all gut and hepatic barriers. This route is most often delivered in clinics or medical offices, while other direct NAD+ channels in the market include compounded lower-dose injections and research-use formulations via different routes. Side effects include transient chest tightness and headache during rapid infusion.
