When the body is unable to remove potassium from the body effectively through the kidneys this can cause heart failure. Certain medications can cause a potassium deficiency which also leads to heart problems. The body needs potassium to live so it is important that the body is able to produce enough potassium that is filtered back into the bloodstream through the nephrons in the kidneys. Nephrons are the actual filters inside your kidneys, the nephrons are responsible for fluid transport through to the bloodstream. The renal corpuscle(think of a letter no not A,B, or C but one you would write and actually mail); the renal corpuscle is the FROM as it is responsible for filtering would be toxins from the bloodstream and the renal tubule is the TO, it's responsibility is to filter non toxins back into the bloodstream.
Alkaline water assists the kidneys in being more effective in removing toxins from the body and has an overall effect on kidney health in general because it improves kidney function. Alkaline water can also reduce uric acid retention or when the kidneys are prevented from expelling uric acid out of the body by urine. The subsequent buildup of uric acid in the body can cause gout, kidney stones and contribute to renal or kidney failure. Uric acid is needed for the digestion of foods. When you have too much uric acid it usually forms crystals in the joints of the bones in the body. To remove excess uric acid, alkaline water would be useful.
Keep those kidneys in line with alka-line water!
