NAD+ is found in every cell of our body and it’s essential for empowering and protecting our cells. When we have high levels of NAD+ in our bodies, cellular energy increases which becomes the fuel of life. Sirtuins are a family of seven proteins that help regulate your cellular health. They play an important role in aging. However, sirtuins can only function in the presence of NAD+. In other words, if NAD+ levels are low, then sirtuins can’t do their job properly.
