Nad Supplement Buyer's Guide
Written by Libby JohnsonIntro to NAD Supplement
NAD stands for nicotinamide adenine dinucleotide, and is a coenzyme found in all living cells. NAD helps regulate the energy in cells, and is essential for cells to perform their metabolic activities.

In this buying guide, we will explore the different types of NAD supplement available, their benefits, and how to choose the best one for you.
Types of NAD Supplement
NAD supplements come in two main forms, NADH and NR. NADH is the active form of NAD, and helps to increase energy levels, boost mental clarity and focus, and even help to improve sleep quality.
