Healthy aging and muscle function are positively associated with NAD+ abundance in humans

Cross-Sectional Study

Similar Assertions

Older people have lower levels of a key molecule in their muscles that helps keep cells healthy, especially if they're not active — but those who stay active, like endurance athletes, tend to keep their levels much higher.

As we age, levels of a molecule called NAD+ go down, and this might mess up how our cells' powerhouses work, especially in the brain and liver, possibly leading to diseases like Alzheimer's or diabetes.
