Indigo H2O is one of the best filtered waters available. This is a high quality mineral water with alkaline levels that are beneficial to your body. Calcium, magnesium, and potassium are easily absorbed because they appear naturally in the water as mineral hydrates. A glass of Indigo has the same amount of calcium and magnesium as a glass of whole milk. There was once a glacier that occupied the area that is now known as Lake Michigan. The remnants of this glacier are the water source for Indigo H2O. The water is drawn from a naturally fed artesian well in the rural Midwest. Indigo H2O is then sent through a UV light technology system and an energy frequency process to remove impurities. These processes preserve the high pH balance of 8.8. The end result is a high quality filtered water that is good for you and tastes fresh and clean.
