Healthy Origins Natural D-Ribose
D-Ribose is a naturally occurring pentose (5-Carbon) sugar, which is a primary building block in the production of Adenosine Triphosphate (ATP) - the body''s main energy source. ATP levels can become severely depressed following periods of rigorous exercise and metabolic stress. Supplementing with D-Ribose may help replenish depressed levels of ATP and improve workout recovery. Consider Healthy Origins 100% Natural CoQ10 in combination with D-Ribose for enhanced cardiovascular support.
