If you want to optimize your metabolic health and prevent or treat metabolic disorders, such as diabetes, obesity, or fatty liver disease, you may benefit from taking NAD+ supplement. NAD+ supplement increases the availability of NAD+, which is a coenzyme that regulates the glucose and lipid metabolism in your body. NAD+ also modulates the insulin sensitivity and the inflammatory response in your tissues. NAD+ supplement may help lower your blood sugar levels, reduce your body fat, and improve your liver function.
