Pick NR or NMN The Longevity Science Showdown
In 2024, researchers documented a 4-fold rise in whole-body NAD+ after a 1000 mg daily dose of NR, directly linking it to faster muscle recovery. That surge gives NR a clear edge for quick NAD+ replenishment, yet NMN nudges muscle fibers toward endurance-type slow-twitch cells, making the choice hinge on
