Isotonix products are formulated with the proper balance of fructose, d-glucose, citric acid, potassium bicarbonate and other key ingredients to assure that they are isotonic when properly prepared. This combination of ingredients is necessary to maintain the ﬂavor, isotonic character, pH and delivery efﬁciency of these nutritional supplements. Normally, when you ingest a daily vitamin or nutritional supplement tablet, your body must work for up to four hours digesting and absorbing the vitamins and nutrients. During this lengthy breakdown process, a percentage of the nutritive value is lost. But because Isotonix products are powders, none of the ﬁllers, binders, coatings and lubricants that are common to tablet manufacturing are necessary. There are no gelatin capsules or ﬁllers. As a result, the amount of time and work necessary to absorb a supplement is greatly decreased.
