This Supplement May Be The Key to Your Fitness Goals This Year

When you take NR, your body converts it into nicotinamide adenine dinucleotide (NAD+), a coenzyme that exists in all cells and factors into energy metabolism and your ability to maintain proper cell functioning. NAD+ also plays a vital role in your energy levels: NAD+ is what fuels your mitochondria, which inturn fuels your body by creating energy. This, researchers think, is how the supplement aids in recovery: By supporting cell rejuvenation thereby helping your body recover and rebuild between workouts. 

In fact, one animal study showed that increasing levels of NAD+ also may help improve muscle function as you age. The study, published in the journal Cell Metabolism, found 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 critical component of strength and endurance.*

In another study, researchers used mice whose genes were altered so their muscle tissue contained only 15% of the normal amount of NAD+. They then measured muscle strength and endurance, which was pretty low. But after giving the mice NR-enriched water for just a week, their exercise capacity was that of a normal, healthy mouse.* And in one additional mouse study, supplementation with NAD+ precursors led to better-supported DNA repair and health of muscle tissue within the first week—to the point where researchers couldn’t tell the difference between the tissue of a mouse that was 2 years old versus a mouse that was 4 months old.*
