What is Doctor’s Best Energy Featuring NIAGEN™?
Doctor’s Best Energy Featuring NIAGEN™ facilitates glucose and fat utilization and enhances mitochondrial energy production.* It supplies nicotinamide riboside, a nutrient involved in human energy production and metabolic regulation. Nicotinamide riboside occurs naturally in foods, and is a precursor for nicotinamide adenine dinucleotide (NAD), which our mitochondria use to make ATP. Nicotinamide riboside also helps regulate energy utilization to support structural integrity in the brain, muscles, liver and other organs. *
How does it work?
As a dietary supplement, the nicotinamide riboside from NIAGEN™ is converted into NAD. Nicotinamide adenine dinucleotide (NAD is converted into chemical energy, primarily, in the form of ATP (adenosine triphosphate) There are other enzymatic processes not directly involved in energy production that also require NAD. Human cells contain at least 7 sirtuin enzymes, which are widely distributed and regulate a great variety of life processes. The sirtuins are directly responsive to NAD—when NAD is high the sirtuins are active, and when NAD is low they become inactive. The sirtuins likely serve as “NAD sensors”, responding to changing NAD levels by stimulating or inhibiting other key enzyme systems. As a convenient dietary source of NAD, nicotinamide riboside supports the beneficial actions of the sirtuins.
