What Is NAD+ IV Therapy? How It Works
Updated October 20, 2026 · 3 min read
You sleep. You eat well. You exercise. And yet some days, your energy just isn't what it used to be.
Part of the story may be happening at the cellular level, and that's where NAD+ comes in.
Here's what NAD+ is, why levels decline, how NAD+ IV therapy at iCRYO Westminster works and who it might help.
What Is NAD+?
NAD+ stands for nicotinamide adenine dinucleotide. It's a coenzyme, a helper molecule that your cells need for hundreds of reactions.
Two of its most important jobs:
- Energy production. NAD+ helps your mitochondria convert food into usable cellular energy.
- Cellular maintenance. NAD+ supports enzymes involved in DNA repair and healthy cell function.
Why Do NAD+ Levels Decline?
Research shows NAD+ levels tend to drop as we age. Stress, poor sleep, alcohol and intense physical demands may also use it up.
Lower NAD+ is linked with many of the cellular changes associated with aging, which is why it's become a major focus of longevity research.
How NAD+ IV Therapy Works
NAD+ taken by mouth isn't absorbed well. IV therapy delivers it directly into your bloodstream, bypassing digestion.
Because NAD+ can cause temporary discomfort if infused too quickly, it's given as a slow drip. Our team adjusts the rate to keep you comfortable.

- Health screening with our medical team
- IV placement, a quick pinch
- A slow, steady drip while you relax

NAD+ vs. Niagen
iCRYO Westminster also offers Niagen, an NAD+ precursor that helps your cells make their own NAD+. Read Niagen vs. NAD+ IV to compare.
NAD+ Myths vs. Facts
Myth: "NAD+ is just another vitamin." Fact: NAD+ is a coenzyme your cells use in hundreds of reactions, including energy production. It's made from vitamin B3, but it's not a vitamin itself.
Myth: "An NAD+ pill works the same as an IV." Fact: NAD+ is poorly absorbed by mouth. Most oral products contain precursors your body must convert. IV delivers NAD+ directly into your bloodstream.
Myth: "Feeling discomfort means something is wrong." Fact: Temporary flushing, pressure or nausea during an NAD+ IV usually means the drip is running too fast for your body. Slowing it down typically resolves the sensations within minutes.
Myth: "NAD+ reverses aging." Fact: NAD+ supports cellular processes linked to healthy aging, and research is exciting, but no treatment reverses aging. It's one tool in a healthy-aging routine.
