There is a lot of uncertainty about the pathways NAD+ and precursors take in the body. We do know that there are differences between them, and they have an affinity for different tissues.

There is research showing impressive results for endurance and blood vessel growth in muscle with NMN which have not yet been duplicated for NAD.

NAD+ has been shown to cross the blood-brain barrier intact, while NMN does not.

NR is particularly effective at elevating NAD+ levels in the liver.

We provide all three in one capsule to better address all parts of the body that may benefit from restoring NAD+ levels.
