Tru Niagen is a unique form of vitamin B3 that helps to support levels of Nicotinamide Adenine Dinucleotide in cellular health. When we think of our health we focus on our hair, skin, and mussels. But, our bodies are made up of trillions of individual cells working together to keep us thriving. Nicotinamide adenine dinucleotide (NAD) is essential to all cells containing mitochondria. Each capsule of Tru Niagen contains Niagen which has 263mg of nicotinamide riboside. In clinic studies, Niagen has been shown to increase NAD levels in the blood for the maintenance of good health.
