Creatine monohydrate is converted to creatine phosphate crp in muscle tissue. Crp provides a critically important store of energy which helps to power short bursts of intense muscular activity, as in sprinting or weightlifting. Crp may be present in muscle tissue at levels at least five times higher than the other major energy storehouse molecule-ATP. Crp is used up in regenerating the ATP consumed during intense exercise and is itself renewed when creatine interacts with ATP during the rest period immediately after strenuous exercise. Suitable for vegetarians and hypoallergenic.
