Anyone who may require hydration. O.R.S Hydration Tablets are used by professional athletes, people taking exercise and participating in sport, people travelling and those who may be suffering from low hydration levels. O.R.S Hydration Tablets are considered by many to be a travel essential. Flights, particularly long haul flights, hot climates or even a day of energetic skiing can all lead to low hydration levels. Oral re-hydration solutions allow your body to absorb water almost as soon as you drink it using a scientific process called osmosis. The perfectly balanced mix of electrolytes combined with just a small amount of glucose, quickly restores electrolyte balance and creates an osmotic gradient that allows water to flood into your bloodstream and stay there. Because fluids are absorbed straight away and flow around the body earlier on rather than traveling through the entire digestive system, you feel the health benefits of proper hydration up to 3 times faster.
