A.C.T.™ or "activated cellular therapy" is the world's first healthy energy drink and a healthy "feel good" drink. A.C.T. is designed to activate metabolic pathways (Krebs cycle) to create energy at the mitochondrial sub-cellular level rather than increase fuel (calories). As a result, the energy effect created by the A.C.T. formula is generated for hours - a totally different approach from that of energy drinks that supply a short "spike" of energy produced by large doses of sugar.*
