If you want to support your NAD+ levels, iCRYO Mauldin offers two paths: NAD+ IV therapy and Niagen.

Both aim for the same goal, but they get there differently. Here's how to choose.

Quick answer: NAD+ IV therapy delivers NAD+ directly into your bloodstream through a slow drip that can take a couple of hours and may cause temporary discomfort. Niagen (nicotinamide riboside) is a well-studied precursor that your cells convert into NAD+, and many people find the experience shorter and more comfortable.

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.
