Basis
NAD+ Supplement
Live your best life with healthy cells. Basis supports cellular health by increasing and sustaining NAD+ levels and activating sirtuins.
Support Your Cellular Health
Scientists have made incredible progress in understanding how cellular health works in the last 25 years, and one thing they’ve learned is that a molecule called NAD+ is hugely important. It’s indispensable for life, and levels decline as we age. Now it’s possible to get more cellular NAD+ with Basis.
Thanks to science, you can support your cellular health.

How Basis Works
The culmination of more than 25 years of aging research, Basis is a proprietary formulation of crystalline nicotinamide riboside and pterostilbene that supports cellular health by increasing and sustaining NAD+ levels and activating sirtuins.

Basis Increases NAD+ Levels, Safely and Sustainably
Our double-blind, randomized, placebo-controlled clinical trial demonstrated that Basis can increase cellular NAD+ levels by an average of 40 percent.

Setting A New Standard for Quality and Purity
Most companies that make health products source their ingredients from the lowest cost third-party suppliers, which often requires a trade-off with respect to quality. At Elysium Health, quality is first and foremost.


In the end, the science, and that Elysium was connected to an MIT scientist, was what sold me on trying Basis for a month. Now I’m in my second year of taking it.
