What Does an NAD+ IV Feel Like? First-Session Guide
Updated October 20, 2026 · 2 min read
If you've heard stories about NAD+ IVs, you may be a little nervous. Some people describe flushing, chest pressure or nausea. Others say it was relaxing.
Here's the truth: most of the discomfort people talk about comes from infusing NAD+ too quickly, and it's manageable. This guide walks you through exactly what to expect at your first NAD+ IV at iCRYO New Braunfels.

Before Your Session
How to prepare
- Eat a light meal beforehand. An empty stomach can make nausea more likely.
- Hydrate. The Texas heat makes this extra important.
- Clear your schedule. NAD+ infusions take longer than a regular IV drip.
- Bring something to do: headphones, a book or your laptop.
- Wear comfortable clothes with sleeves that roll up easily.
Health screening
Our medical team reviews your health history and medications before your first infusion.
During Your Session
IV placement
You'll feel a quick pinch as the IV is placed, then the drip begins slowly.
What you might feel
As NAD+ enters your bloodstream, you may notice:
- Warmth or flushing
- A feeling of pressure in your chest or stomach
- Mild nausea
- Muscle tightness or cramping
- A sense of restlessness
These sensations are temporary. They usually ease within minutes once the drip is slowed.
Speak up
This is the most important tip: tell our team how you feel. We'll adjust the rate to keep you comfortable. There's no prize for toughing it out.
After Your Session
Responses vary:
- Some people feel energized and clear-headed right away
- Others feel tired that day and notice more energy the next day
Drink water, eat a balanced meal and go easy on yourself the rest of the day.
Common First-Timer Questions
Is it painful? The IV pinch is brief. The infusion sensations are uncomfortable for some people but not painful for most, especially at a slow rate.
Will I feel this every time? Many people find later sessions more comfortable as they learn what to expect and settle into the right drip rate.
Can I drive afterward? Most people can. Let our team know if you feel lightheaded.

NAD+ infusions often take longer than standard IV drips, commonly a couple of hours, depending on dose and your comfort.
