D-Ribose 450 g by Ecological Formulas is a dietary supplement containing a naturally-occurring monosaccarride needed by the body to perform a number of metabolic processes that are essential to good heart health. Because D-Ribose helps to replenish and build new ATP (adenosine triphosphate) in the body, taking a high-quality supplement to ensure enough reserves of D-Ribose may be beneficial. This easy to use powder form can be mixed with water or juice in order to promote heart health. D-Ribose is directly responsible for helping to rejuvenate heart cell muscles. Clinical studies have shown that D-Ribose has a powerful effect in helping to protect heart muscle after it has been stressed.* Because low ATP levels can delay recovery, taking D-Ribose 450 g is a proactive way to support heart muscle as part of a cardiac rejuvenation program. Supplying the body with sufficient D-Ribose has been shown to support the heart's ability to pump blood by supporting this organ's ventricular functions.*
