ATP (adenosine triphosphate) is the energy currency of the cell and provides the power all cells need to function. Anything that can aid or improve that process is going to be important for all cells, and ribose has been shown to significantly accelerate energy synthesis and recovery. Ribose is a simple five-carbon sugar that is an essential component of important biological molecules called nucleotides, which are used to make ATP and the genetic material, RNA and DNA. D-Ribose is the fundamental building block of ATP, the energy molecule, so without sufficient ribose in the cell, ATP cannot be formed, and the cell becomes starved of energy. The availability of D-Ribose in cells is therefore a limiting factor in energy recovery following cellular stress. The use of D-Ribose (along with gPLC and CoQ10) is gaining popularity among the world\'s leading cardiologists as a way to optimise heart energy production and improve recovery after cardiac events or surgery. Recovery from exercise is also affected by the availability of ATP; the addition of D-Ribose to the body assists in reducing postexercise fatigue and muscle soreness by recycling ATP. D-Ribose also appears to be supportive of normal muscular energy production in those with fibromyalgia and chronic fatigue.
