On reading the ingredients in club soda I notice that the main ingredient is sodium bicarbonate,sodium citrate, potassium sulphate( potassium sulphate is known as Kali sulp) a homeopathic tissue salt for urinary infection detox and diabetes,other ingredients

they also add carbonated water for the fizz. Try two eight ounce glass daily, you may add lemon for addition flavour.

Please let me know if other individuals have this experience.
