NAD SPORT

Metabolic health—which describes your body's ability to regulate blood sugar, insulin, cholesterol levels, and more —could be improved by NAD in some ways.

Research shows that increased levels of NAD in the body seem to support health conditions like obesity and metabolic syndrome. These conditions can increase your risk of developing heart disease, stroke, and type 2 diabetes.162

A small 2021 study of postmenopausal people with prediabetes who had excess weight or obesity found that taking 250 milligrams (mg) of NAD per day for 10 weeks improved insulin sensitivity.17 Other studies have found improvements in body composition, lipid levels, exercise capacity, and muscle composition with NAD supplementation.1819

Because these findings are relatively new, additional studies are needed to better understand this connection.20
