How do NAD+ injections and nasal sprays differ?
Short answer
NAD+ injections and nasal sprays use different delivery methods and need different instructions. An injection uses a needle, while a nasal spray is applied inside the nose. Neither method has well-established wellness benefits in healthy people. Results vary. Do not switch forms or convert doses without your prescribing physician's guidance.
NAD+ injections and nasal sprays differ in how they are given, how they are prepared, and the handling they require. An injection uses a needle and must follow the exact route on the prescription. A nasal spray is applied inside the nose using its own device and directions.
Do not assume that one method works faster, is better absorbed, or provides greater benefits. Evidence comparing these forms for wellness use is limited. Results vary. A dose used for one form cannot be treated as an equal dose of the other.
Injections require training on clean technique, measuring the prescribed amount, and safe needle disposal. Nasal sprays require product-specific instructions for preparing the device, applying each spray, and keeping the tip clean. Never share needles, syringes, or nasal spray devices.
Compounded medications are prepared by a licensed pharmacy for one patient and are not FDA-approved. A licensed physician in your state decides whether treatment and a particular form are appropriate. Ask the pharmacy for instructions before your first dose if anything is unclear.
