NAD+ (nicotinamide adenine dinucleotide) is a coenzyme every cell in your body uses to produce energy and carry out repair processes. When people ask how long NAD+ IV therapy “takes to work,” they are usually asking two different things: how long the infusion itself takes, and how long before you notice anything.
How long is the infusion?
A single NAD+ session typically runs two to four hours, considerably longer than a standard hydration or vitamin drip, which usually finishes in 30 to 60 minutes. The reason is tolerance: NAD+ has to be infused slowly. Running it too fast commonly causes chest tightness, flushing, or stomach cramping. Slowing the drip rate resolves these sensations almost immediately, which is why a licensed registered nurse stays with you and adjusts the pace throughout the session rather than starting the bag and leaving.
When do people notice an effect?
This varies a lot between individuals and is not guaranteed. Some people report feeling more mentally clear or energized within a day of a session. Others notice more gradual changes after a short series of sessions spaced over a week or two, followed by monthly maintenance. Because NAD+ research is still developing and it is not an FDA-approved treatment for any specific disease, we do not promise a specific timeline or outcome. It is offered as a wellness infusion, not a diagnosis or cure for anything.
What actually happens during the session
Your nurse arrives at your home, hotel, or Airbnb, reviews your health history, and places a small IV catheter. The NAD+ solution, diluted in saline, is then infused at a conservative starting rate. If you feel the tightness or flushing sensation that NAD+ is known for, your nurse slows the drip until it eases. Most people spend the session reading, working, or simply resting.
Who should be cautious
People who are pregnant or breastfeeding, or who have significant heart, kidney, or liver conditions, should avoid elective NAD+ infusions unless specifically cleared by their physician. Our nurses screen for these factors during intake and will decline treatment when it is not clearly appropriate.
