2.. Nicotinamide riboside attenuates age-associated metabolic and functional changes in hematopoietic stem cells.

There are some other posts I've read that discuss the effectiveness of NR in various metabolic functions. In a recently published Harvard paper, scientists have claimed that elderly coronavirus patients should be given anti-ageing drugs (NAD boosters) to make their immune systems 'younger' so they can fight the virus faster.

NAD boosters are supplements that contain nicotinamide riboside, a form of vitamin B3. When taken as a supplement, the body converts the nicotinamide riboside to NAD+ - the prized coenzyme in youngsters. [News Link]
