The kidneys must also pay the price for accumulation of acid waste products: they have to increase their filtering activity and remove these substances from the blood. By drinking alkaline water, we do our kidney a favour. Efficient kidney function is very important for an efficient immune system function and prevention of diseases.
Kidney stones are the result of strong acidification in the kidney. Tiny particles that eventually join to form bigger, harder formations are the salt of phosphoric and uric acid, together with alkalinizing minerals such as calcium and (or) magnesium to buffer the toxic efects of these acids.
Drinking alkaline water prevents the formation of kidney stones or helps the existing stones to dissolve and flush out.
