NADH and CoQ10 are natural coenzymes for NAD+ and ATP. Our NADH plus CoQ10 is a great addition to any NAD+ Boosting regimen! Nicotinamide adenine dinucleotide (NADH) is the biologically active form of niacin (vitamin B3) and function as a biological spark plug in the cellular energy metabolism. It is commonly used as support for energy, memory, concentration and support for physical training and endurance. CoQ10, also known as coenzyme Q10, functions primarily to provide cells with ATP, the primary unit of energy needed for cellular activity. CoQ10 also works as an antioxidant in mitochondria and lipid membranes in your body. It helps to maintain overall cellular health and assists in the regenerating process of other important antioxidants such as vitamin E.
