If you are looking for a way to boost your cellular health and longevity, you may want to consider taking NAD+ supplement. NAD+ supplement contains either NAD+ or its precursors, which are molecules that can be converted into NAD+ in your body. NAD+ is a vital coenzyme that supports the function of enzymes called sirtuins, which regulate gene expression, inflammation, and cellular stress response. NAD+ supplement may help activate sirtuins and protect your cells from damage and deterioration.
