High-pH alkali water hydrates you better than bottled water does, a new Montana State University study found. People who drank mineral-enhanced H20 instead of plain water for two weeks lost less fluid as urine and were more hydrated than plain-water drinkers. Study author Daniel Heil, says the minerals and pH-spiking compounds may help your cardiovascular system retain more water.

How much water should you drink anyways? And how do you know when you have had enough? These are important questions you should ask yourself when staying hydrated.

Water has also been found to keep you regular and helps you lose weight.
