D-Ribose with Peak ATP is the first formula to combine the two most significant developments in the research of energy enhancement. The primary source of energy for all cellular processes is a molecule known as ATP (adenosine triphosphate). Healthy, active cells constantly replenish their supply of ATP to produce vital cellular energy. However, under conditions of stress, injury, or aging, critical body tissues such as heart and skeletal muscles cannot produce ATP quickly enough. People suffering from cardiac or circulatory disease where oxygenated blood flow is decreased are especially at risk. People with fibromyalgia and other debilitating muscular diseases have been shown to have reduced levels of ATP to facilitate muscle function. More than a decade of research confirms that D-Ribose with Peak ATP can help replenish ATP energy pools and enhance cardiac and skeletal muscle function and enhance cardiac energy output.D-Ribose, a naturally occurring sugar used by every cell of the body, is the building block of ATP. Although most cells is the body can produce ribose, in time of stress, injury or poor health, this process is not fast enough to maintain proper cardiac or skeletal muscle function. Research has shown that D-Ribose helps the body to maintain healthy reserve energy pools in the heart and muscle tissues. As early as 1990 clinical trials in Germany showed that D-Ribose administration to patients with severe coronary artery disease increased exercise tolerance and delayed the onset of moderate angina. Since these groundbreaking studies in coronary artery disease, the benefits of D-Ribose have been reported for cardiac surgery recovery, heart failure and neuromuscular disease treatment, restoration of energy to stressed skeletal muscle, and control of free-radical formation in oxygen-deprived tissue. But the energy enhancing benefits of D-Ribose is only the beginning. D-Ribose with Peak ATP is the only D-Ribose product to contain Peak ATP, a patented extract that delivers a bio-identical molecule of ATP. Peak ATP is the only orally administered ATP clinically tested to demonstrate its effectiveness and is backed by the pioneering research of Dr. Eliezer Rapaport, considered one of the world’s foremost authorities on ATP. The toxicology and safety of D-ribose have been exhaustively studied. The supplement is 100% safe when taken as directed. D-Ribose can actually lower blood glucose levels; therefore, insulin-dependent diabetics should check with their physicians before starting on the supplement.
