D-ribose is a naturally occurring sugar present in every cell of the body; it initiates the process of ATP production the molecule required for transfer energy within the body. D-ribose is synthesised from glucose, a gradual and complex process which utilises a high energy output. Supplemental ribose can help to bypass this process, rapidly re-building cellular ATP and returning muscle energy levels to normal. Greater ATP generation leads to more efficient energy production during high impact exercise, and so can prove beneficial to a number of fitness goals.
