NAD stands (nicotinamide adenine dinucleotide) is a molecule found in every cell in your body. NAD helps your cells make energy by carrying electrons from one chemical reaction to another. This process powers everything your body does, and it keeps your cells working properly as you get older.
NAD helps your cells work and stay healthy. As you age, NAD levels naturally decline. Some cells begin using NAD more quickly than your body can replace it, lowering overall levels.
With less NAD available, cells may have a harder time making energy and repairing damage. Lower NAD levels have been linked to age-related changes, including:
-
Muscle weakness and fatigue
-
Eye conditions, like vision loss and glaucoma
-
Metabolic disorders, including Type 2 diabetes and obesity
-
Heart issues, like arrhythmia and heart failure
-
Cognitive decline, including slower thinking and memory loss
Researchers continue to study how NAD levels may affect aging. Supporting NAD production may help maintain cell function over time.
