what is NAD+

NAD+, or nicotinamide adenine dinucleotide, is a molecule essential for life. It is a cofactor that participates in a wide range of biochemical reactions, including cellular respiration, DNA repair and energy metabolism.

NAD+ is found in all cells in the body. It is produced from vitamin B3, or niacin.

NAD+ functions include:

Cellular respiration: NAD+ is an essential cofactor for cellular respiration, the process by which cells produce energy.
DNA Repair: NAD+ is necessary for DNA repair, the process by which cells repair DNA damage.
Energy metabolism: NAD+ is necessary for energy metabolism, the process by which cells convert food into energy.
NAD+ levels decrease with age. This can contribute to a number of age-related health problems, such as Alzheimer's disease, Parkinson's disease, and diabetes.

There are a number of factors that can reduce NAD+ levels, including:

Diet: A diet deficient in vitamin B3 can reduce NAD+ levels.
Stress: Stress can increase NAD+ consumption.
Disease: Some diseases, such as diabetes and Alzheimer's disease, can reduce NAD+ levels.
There are a number of things that can be done to increase NAD+ levels, including:

Eat foods rich in vitamin B3: Foods rich in vitamin B3 include liver, mushrooms, poultry, eggs, and dairy products.
Taking NAD+ supplements: NAD+ supplements are available without a prescription.
Reduce stress: Stress reduction techniques, such as yoga and meditation, can help reduce NAD+ consumption.
Research on NAD+ is ongoing. Scientists are exploring the use of NAD+ to treat a number of diseases, including Alzheimer's disease, Parkinson's disease and diabetes.
