Jarrow Formulas Ribose is present in all the cells of the body and helps boost strength level of muscles. Ribose is a carbohydrate naturally found in all cells of the body. Physical stress can increase the loss of nucleotides (such as ATP, ADP and AMP) from the heart and skeletal muscles. Ribose metabolizes into 5-phosphoribosyl-1-pyrophosphate (PRPP), which is a rate limiting substrate used in the synthesis of nucleotides.

Ribose is used in an attempt to boost strength levels, enhance gains in muscle size and strength and prevent muscle tissue breakdown that can occur subsequent to strenuous exercise. By supplementing with ribose, an athlete can increase their muscle ATP levels and thereby produce more energy during short, intense bursts of activity, like weight training and sprinting. All muscles in the body rely on a constant supply of ATP for the energy they need to function properly. When we place great energy demands on our heart or skeletal muscles through intense physical exercise, our muscles become deprived of oxygen due to diminished blood flow. This oxygen deprivation leads to a drastic decrease in muscle ATP/energy levels. Studies have shown that muscle ATP stores can be decreased by as much as 60-70% following exhaustive exercise and that it can take over 72 HOURS for these ATP stores to be adequately replenished
