Once you take NR, your physique converts it into nicotinamide adenine dinucleotide (NAD+), a coenzyme that exists in all cells and elements into power metabolism and your potential to keep up correct cell functioning. NAD+ additionally performs an important function in your power ranges: NAD+ is what fuels your mitochondria, which inturn fuels your physique by creating power. This, researchers assume, is how the complement aids in restoration: By supporting cell rejuvenation thereby serving to your physique get well and rebuild between exercises.
In truth, one animal examine confirmed that growing ranges of NAD+ additionally might assist enhance muscle operate as you age. The examine, revealed within the journal Cell Metabolism, discovered that mice that had depleted levels of NAD+ had a “dramatic” drop in their muscle strength and endurance on a treadmill, implying that NAD+ is a vital element of energy and endurance.*
In one other examine, researchers used mice whose genes had been altered so their muscle tissue contained solely 15% of the traditional quantity of NAD+. They then measured muscle energy and endurance, which was fairly low. However after giving the mice NR-enriched water for only a week, their exercise capacity was that of a normal, wholesome mouse.* And in a single extra mouse examine, supplementation with NAD+ precursors led to better-supported DNA repair and health of muscle tissue inside the first week—to the purpose the place researchers could not inform the distinction between the tissue of a mouse that was 2 years previous versus a mouse that was 4 months previous.*
