Healthy Drinking Water is the Precondition for  Human Health 

Water is a fundamental human need and is obviously essential for hydration and for food production.

Water that contains natural minerals and is slightly alkaline is associated with lower mortality from heart disease and cancer and overall good health.  Healthy water should not contain harmful substances and should contain vital minerals - calcium, magnesium, and bicarbonates. 

Calcium: The human body uses 99 percent of its calcium to support its skeletal structure and function. The rest of the calcium is used in cell signaling, blood clotting, muscle contraction and nerve function. Inadequate intakes of calcium have been associated with increased risks of osteoporosis, kidney stones, colorectal cancer, hypertension and stroke, coronary artery disease, insulin resistance and obesity. Most of these disorders have treatments, but not cures.

Magnesium is a cofactor for some 350 cellular enzymes, many of which are involved in energy metabolism. It is also involved in protein and nucleic acid synthesis and is needed for normal vascular tone and insulin sensitivity. Low magnesium levels are associated with endothelial dysfunction,  increased vascular reactions, elevated circulating levels of C-reactive protein (a proinflammatory marker that is a risk factor for coronary heart disease) and decreased insulin sensitivity. Low magnesium status has been implicated in hypertension, coronary heart disease, type 2 diabetes mellitus and metabolic syndrome. 

Bicarbonates play a vital role in buffering acids in the body and give blood the ability to resist changes in pH. Even tiny variations in blood pH can disrupt vital metabolic functions. Bicarbonates in drinking water give water pleasantly clean and refreshing tastes.
