A note from Cleveland Clinic

NAD is always at work in the background, helping your cells turn food into energy and respond to everyday stress. Moving your body, eating foods with the right nutrients and getting enough rest may help give your cells what they need to keep going strong. By helping NAD out, you may be able to support yourself, now and in the years ahead.

01What are NAD boosters?+

Nicotinamide adenine dinucleotide (NAD) is one of the indispensable cofactors in the body that plays a crucial role in redox regulation and also acts as a signaling molecule in various metabolic and other biological pathways. The terms NAD+ and NADH refer to oxidized and reduced forms of NAD, which are prerequisite for over 500 enzymatic reactions in several biological processes. NAD boosters are small molecules that are required to increase cellular NAD+ levels. These molecules are particularly promising because of the anti-aging or lifespan-promoting effects. With age, a depletion in NAD+ level occurs, which is considered as a hallmark of aging. A depleted NAD+ level is also associated with many age-related disorders, such as metabolic disorders and neurodegenerative diseases. Some animal studies have indicated that an increase in cellular NAD+ level can significantly slow the aging process, as well as delay the onset and progression of many age-related disorders. In general, NAD+ level can be increased by supplementing NAD+ precursors, increasing NAD+ synthesis, or inhibiting NAD+ degradation.
