NAD+ Injection vs Spray
Injection bypasses gut absorption. Nasal spray is easier. The question is which one your body actually uses.
NAD+ is the same coenzyme regardless of how it enters your body. The choice between injection and nasal spray is mostly about bioavailability, convenience, and how much active NAD+ ends up in tissue. Oral NAD+ is poorly absorbed, which is why neither of these routes goes through the gut.
Side by side.
Who picks which.
- Want the highest tissue NAD+ levels
- Already comfortable with subcutaneous injections from GLP-1 or peptides
- Needle-averse
- Want a daily, low-dose maintenance option vs. weekly higher-dose sessions
Injection delivers more NAD+ per session and is the standard for clinical protocols. Spray wins on convenience and is reasonable for daily maintenance. Many members use injection for a loading phase and switch to spray for maintenance.
