Niagen vs. NAD+ IV: What's the Difference?
Updated October 20, 2026 · 2 min read
If you want to support your NAD+ levels, iCRYO Westminster offers two paths: NAD+ IV therapy and Niagen.
Both aim for the same goal, but they get there differently. Here's how to choose.
How NAD+ IV Works
NAD+ is infused slowly into a vein. Because it can cause temporary flushing, chest or stomach pressure or nausea if given too fast, the drip rate is adjusted for comfort.

How Niagen Works
Niagen is nicotinamide riboside, a form of vitamin B3 that your cells convert into NAD+ through a natural pathway. Human studies show it raises NAD+ levels.
