NAD+

Nicotinamide adenine dinucleotide, commonly known as NAD+, is a crucial compound with various essential roles in cellular processes. As the oxidized form of NADH, it participates in carrying electrons between biochemical reactions, facilitating the transfer of energy within cells. NAD+ is integral to fundamental biological functions, including enzyme activation/deactivation, posttranslational modification of proteins, and intercellular communication. Beyond its intracellular activities, NAD+ also serves as an extracellular signaling molecule, being released from neurons in various tissues, such as blood vessels, the bladder, the large intestine, and specific neurons in the brain.

Research has illuminated the potential benefits of NAD+ in diverse physiological aspects. One significant area of interest is its impact on aging-related processes. Studies suggest that NAD+ may have a role in mitigating the effects of aging, with implications for muscle function and the protection of cells in the nervous system.
