What is NAD+?
NAD+ (Nicotinamide adenine dinucleotide) is a coenzyme that plays a crucial role in various cellular processes, including energy metabolism, DNA repair, and cellular stress response. NAD+ levels decline with age, and supplementation with NAD+ has been shown to have beneficial effects on health and longevity.
How does NAD+ work?
NAD+ is found in every cell in your body and is essential for creating cellular energy and maintaining cellular health. NAD+ helps to regulate the body's energy production by stimulating the production of ATP, the body's primary source of energy. In the body, NAD+ is primarily stored in the mitochondria, which are the powerhouse of the cells responsible for producing energy.
What NAD+ dosing is right for me?
NAD+ injections are available as 500mg and 1,000mg vials, as well as 4,500mg nasal sprays. The dosing for NAD+ varies depending on the individual patient and the specific indication for which it is being used. NAD+ should only be taken under the guidance of a healthcare provider.
