10 min : Glucose activates SGLT1 sodium-glucose co-transporters in the small intestinal epithelium. Sodium is actively pulled across the gut wall, dragging water molecules with it via osmosis. Absorption rate at this stage is nearly double that of plain water.

30 min : Taurine (2000mg) and B-vitamins now active. The combined adenosine blockade and dopamine modulation from the larger caffeine dose produces a more pronounced stimulant effect than Red Bull at equivalent body weight.

45 min : Potassium reaches intracellular compartments, restoring the Na⁺/K⁺ gradient disrupted by sustained muscle contraction. Sodium triggers hypothalamic osmoreceptors, actively stimulating continued drinking — the thirst-driving mechanism that distinguishes electrolyte drinks from plain water.

5–6 hour half-life : Plasma volume is maintained at pre-exercise levels. Sweat sodium losses are approximately 60–70% replaced at 500ml/hr consumption. Glycogen sparing from exogenous glucose extends endurance performance — the original 1965 research finding that justified the entire sports drink category.
