After reading all of the questions and replies, I am still mildly confused as to the difference if any in the CR and SR that appears after Potassium Chl. I get the CR is Controlled Release but is SR for Sodium Free? This supplement has a lot of different letters associalted with it and can make it confusing to know exactly how much you are taking and what you should or should not take.
Potassium chloride has many uses such as being a sodium-free substitute for table salt (sodium chloride). Research I have gathered states that this pill works by providing a direct replacement of potassium in the body.
