Hydralyte rehydrates faster than water!

Prevention and treatment of dehydration in patients involves absorption of water and electrolytes from the small intestine into the bloodstream. The key to effective absorption is the coupled transport of glucose and sodium molecules, which occurs at the intestinal surface. Glucose stimulates sodium uptake, and water absorption follows. The absorption of potassium, chloride and citrate occurs simultaneously with sodium transport.

Potassium appears to be absorbed by a “solvent drag mechanism” i.e. it is pulled along with water. Citrate and chloride are absorbed to maintain charge balance across cell membranes.

The concentration of glucose and electrolytes in Hydralyte ORS is optimal for rapid and effective hydration and electrolyte replacement.
