Most physician-guided programs recommend two to five injections per week depending on your goal and protocol phase. General wellness and maintenance protocols typically run two to three times per week, while energy, metabolic, and anti-aging programs often call for three to five injections per week during the loading phase. Your provider will determine the right frequency based on your health history, starting NAD+ levels, and treatment goals.
The loading phase — typically the first four to eight weeks — usually involves higher injection frequency to rapidly elevate NAD+ levels from a depleted baseline. Maintenance phases that follow are generally less frequent, often two to three times per week, since the goal shifts from restoration to preservation. Your provider will guide the transition between phases based on how you are responding.
Daily NAD injections are used in some high-dose recovery and anti-aging protocols, particularly during the initial loading phase. Daily injection schedules are more common in clinical settings or for patients with significant NAD+ depletion who need faster restoration. Most at-home programs settle into a three to five times per week schedule rather than daily dosing for long-term sustainability.
Injecting more often than your prescribed protocol without provider guidance can increase the risk of side effects including injection site reactions, nausea, and fatigue. It can also make it harder to assess how you are actually responding to the therapy since the dosing variable becomes inconsistent. Always follow your prescribed schedule and consult your provider before making any frequency adjustments.
Most people continue NAD injections for at least three to six months to fully experience the benefits of the therapy, particularly for energy, metabolic, and anti-aging goals. Some patients maintain ongoing lower-frequency protocols indefinitely to sustain the improvements they achieved during the loading phase, while others take periodic breaks and resume as needed. Your provider will help you determine the right long-term approach based on your goals and how your body responds over time.
