“But until now, it was unknown whether NR reached targeted organs like the brain to have a real therapeutic effect,” according to Christopher Martens, one of the key researchers in this study, and the director of the Delaware Center for Cognitive Aging Research.
Resveratrol is a polyphenol derived from plants with antioxidant properties that have been shown to enhance the activation of the body’s own self-repair proteins, called sirtuins. When sirtuins are activated, the effect is delayed aging, which has been demonstrated in a wide spectrum of experimental models, including mammals.
Researchers use supplementation with NMN, NR and NAD⁺ to restore levels of NAD⁺ in mice, making them look and behave like they did when young and extending their lifespan.
Although they have similar effect in some organs, there may be differences in the effect they have in other tissues throughout the body.
