NAD+

This is a cofactor central to metabolism and involved in energy production in every cell. It is vital for proper brain functioning, digestion, muscle development and function, DNA repair and telomere maintenance. It may be considered an anti-aging molecule due to its many repair and energy functions. Oral NAD supplements are not as useful due to their poor absorption, so intravenous NAD is the fastest way to increase the availability of NAD in the body.
