Nicotinamide adenine dinucleotide, or NAD+ for short, is a coenzyme found in all living cells. Its function is nothing short of miraculous. Imagine you’re running a marathon and you’re on your last stretch, but you’re dying of thirst. If someone handed you a bottle of water, you would drink it, right? Your cells constantly run a 24-hour marathon. They don’t get a break just because you do. And they need fuel and certain tools to keep going strong. NAD is one of the most important tools you can give your cells, and ultimately yourself. Stronger cells equals a stronger you.
