* Ortho¹ Science-Based Nutrition * Dietary Supplement * Authentic Nicotinamide Riboside * Brain Energy Optimizer * Vegan * Non-GMO and Gluten Free Best Energy Featuring Niagen supplies authentic nicotinamide riboside (NR), an Ortho¹ nutrient broadly involved in human energy production and metabolic regulation. NR occurs naturally in foods, and is a metabolic starter for NAD (nicotinamide adenine dinucleotide), which our cells absolutely require to make energy. NR also helps regulate cell energy utilization to support structural integrity in the brain, heart, muscles, liver and other organs. Enhances mitochondrial energy production Facilitates glucose and fat utilization for energy Promotes energy-dependent regulation of cell functions ¹A nutrient naturally built into the body"s chemistry
