Does reverse osmosis filtered water cause mineral deficiency?

Unfortunately, the process of reverse osmosis filtration removes the essential minerals from the water as well as the harmful compounds. Because reverse osmosis water contains no minerals, it can potentially leach minerals from the body when it is consumed. This means that the minerals consumed in the vitamins and food you eat are urinated away.

Reverse osmosis is one of the filtering methods that remove everything from the water, including the essential minerals. While completely clean water sounds like a good option, only drinking reverse osmosis water can be harmful. This demineralized water ends up leaching the minerals from your body, which means that any minerals absorbed through food are urinated away.
