Some people believe that drinking alkaline water can have some health benefits, like better digestion and clearer skin. But be careful not to drink too much. An excessive intake of alkaline water isn't the most healthy thing for your body because it can cause an electrolyte imbalance. Although there are claims that our bodies need a certain amount of alkalinity if the pH balance is off, most experts agree on a general consensus: Alkalinity does not need to be replaced when you're getting enough from natural foods. If alkaline water seems to work for you, make sure to speak to your doctor before making a 100% switch.
