The NAD+ Supplement Made by Scientists

Your cells deserve support. Basis is a daily supplement shown to increase and sustain NAD+ levels when taken daily. Basis also supports hundreds of processes in your cells.

  • Increased NAD+ promotes a healthy cellular aging process
  • Basis activates sirtuins, which play a key role in regulating cellular health
  • Increased NAD+ supports cellular energy and maintains healthy DNA

Our Basis Formula

Basis is a proprietary formulation of nicotinamide riboside and pterostilbene, which support cellular metabolism as you age. Each batch of Basis is tested for quality and purity during and after manufacturing, as well as by independent, third-party labs.

Nicotinamide Riboside (NR)

NR is a unique form of vitamin B3 and a highly efficient precursor to NAD+, meaning your body converts it to NAD+ via metabolic pathways. Elysium's NR (NR-E) is patent-pending and proprietary. 

Pterostilbene (PT)

PT is a powerful polyphenol that works synergistically with NR to activate sirtuins. PT is chemically similar to resveratrol but more bioavailable, meaning it is better absorbed by your body.


In addition to our commitment to clinically testing our products in rigorous human trials, we're equally committed to purity and quality, and we third-party test every batch of Basis for that reason.
