Unfortunately, we are born with optimum NAD+ levels, but this amount dramatically decreases with each decade as we age, falling to dangerously low levels by the time we reach age 60 and beyond. Maintaining a more youthful metabolism could mean a higher resting metabolic rate, resistance to weight gain, and the ability to maintain muscle mass and resist tissue damage over time, says Brenner, who recommends daily NR supplementation to restore beneficial NAD+ levels. Other studies show that restoring healthy NAD+ levels also restored healthier looking skin and hair, and may help prevent hair loss in both men and women.
