Please note: 20% of daily water intake comes from food


We do not recommend or advise excessive water consumption - While it isn’t common, you can drink too much water. Athletes whom spend hours running, rowing or cycling would consume a lot of water but even if you are quenching your thirst you do run the risk of developing hyponatremia meaning that your sodium level is lower than it should be. If you feel fatigued, get a headache and have no appetite we recommend consulting a health professional immediately. Hyponatremia can be prevented during large amounts of exercise by adding a dash of salt to your water.

The recommended daily intake for active adults from The Food and Nutrition Board of the Institute of Medicine state that Men need 3.7 litres of water daily, while women should aim for 2.7 litres. Water intake is not solely through drinking water, on average 20% of water intake comes from daily food intake such as fruit and vegetables.


Hot and cold beverages will contribute to daily water intake.
