As a naturally occurring sugar, D-ribose is often taken as a supplement to improve athletic performance and exercise recovery. D-ribose is also said to help support healthy heart function and provide energy for the muscles.

D-ribose is sometimes injected into the vein, but it can also be taken by mouth. When taken by mouth, D-ribose is usually taken in three divided doses per day.
