Hello alka selzer gold is an instant alkalizer but this is only a temporary solution while other permanent measures are taken to alkalize mainly through diet. The sodium and potassium in form of bicarb are indeed alkalyzing and magnesium is easy to obtain also, yet they are but a few of the minerals needed by the body for proper functioning levels. The normal body has an alkaline reserve of minerals stored in the liver which is usually depleted by the time cancer is manifested. It is a slow and steady process to replete the disbalance and taking a product such as A-G the body will soak it up and use it with nothing to store and replete the reserves...Drinking crushed rocks and such is only a temporary measure and a trick to fool the mind while reserves are really being brought up by proper diet and other lifestyle measures.
