Amount of water is judged by urine flow. Urine color should be clear when fully hydrated, light yellow is normal, and the frequency of voiding should be regular and without pain or discomfort when enough water is consumed. When feeling anything uncomfortable, water is the first medicine one should reach for and it provides the best carrier for magnesium, bicarbonate and iodine, making it a valuable medicinal. The ultimate water is high in magnesium bicarbonate which one can buy in some rare bottled waters, or add it from a concentrate. Maximum therapeutic dose is 4 oz. of concentrate to each gallon of distilled water, but one can drink that around the clock. I recommend 8 glasses per day of MagBicarb water.
