Creating and restoring energy largely depends on an important energy molecule made in the cells called adenosine triphosphate (ATP). Fatigue, exhaustion and slow recovery from intense activity result when levels of ATP are low. D-ribose is a simple 5-carbon sugar that is present in and used by every cell in the body to produce energy. Its ability to build new ATP results in energy production that may accelerate recovery from fatigue, support heart function, and make energy available to muscle tissue. Supplementing with D-Ribose powder can support a cell’s ability to create needed energy for the heart muscle. As a building block for ATP molecules, this all-natural sugar is a critical nutrient for helping to keep muscle and heart tissue in good shape. D-Ribose is also ideal for athletes, weekend warriors, and those who enjoy and rely on lots of energy.
