NOW&ampreg; Waxy Maize is a complex starch derived from Non-GMO corn that is naturally high in amylopectin, a high molecular weight, highly branched polysaccharide.&ampnbsp; Unlike typical corn starch products, which contain an average of 70-75% amylopectin, NOW&ampreg; Waxy Maize typically contains 90% amylopectin.&ampnbsp; Amylopectin is slowly absorbed by the body, and then easily assimilated by muscle tissue, where it is converted into glycogen.&ampnbsp; Glycogen can then provide a sustained source of glucose for energy.&ampnbsp; Unlike maltodextrin or dextrose, Waxy Maize supports glycogen resynthesis well after you are finished working out and sustains energy levels throughout the day.*
