Why Do People Take NAD+ Injections?

NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme found in every cell of the body. It plays a key role in energy production, DNA repair, and cellular health. But as we age, NAD+ levels naturally decline — which may contribute to fatigue, slower metabolism, brain fog, and signs of aging.

People take NAD+ injections for a variety of reasons:

• Increased energy and focus

• Faster recovery after workouts or illness

• Improved mood and sleep

• Support for anti-aging and cellular repair

• Detox support, especially in addiction recovery protocols

  
  

Common NAD+ Injection Dosing Schedule

There’s no one-size-fits-all protocol, but here’s a general research-use schedule:

For general wellness and energy:

• 100–250mg, 1–2 times per week

For anti-aging and cellular repair:

• 250–500mg, 1–3 times per week

For intensive detox or recovery support:

• 500–1000mg, daily or every other day for 4–10 sessions

  (typically part of a short-term loading phase)

Important Note: Inject Slowly

NAD+ injections should always be administered slowly — ideally over 1–2 minutes for smaller volumes. Rapid injection can cause:

• Nausea

• Stomach cramping

• Injection site irritation or pain

  
  

This is backed by clinical studies and patient reports: NAD+ moves slowly across cell membranes, so a slower injection gives the body time to process it. Intravenous NAD+ is even more commonly infused over 1–2 hours for this reason.

For subcutaneous or intramuscular use, injecting slowly minimizes discomfort and improves absorption.

As always, NAD+ injections should be used under supervision and for research purposes only, unless prescribed by a licensed medical provider.

How Long Does It Take to Work?

Many report benefits within 1–2 weeks. Some effects, like better sleep or energy, may be noticeable after the first dose. For longer-term benefits, consistency over 4–6 weeks is key.

Always consult your healthcare provider before starting any NAD+ protocol.
