Indeed, sodium is in the foods we eat, but it's also in some of the medicines we take. Some over-the-counter cold medicines, pain relievers (non-steroidal anti-inflammatory drugs), laxatives and heartburn medicines contain sodium-based ingredients, increasing your daily sodium intake every time you reach for a bottle of antacid. Decongestants, in particular, can be hidden sources of sodium.
Be sure to read the ingredients list -- including the inactive ingredients -- and look for sodium-based ingredients such as sodium lauryl sulfate, sodium propionate, sodium starch glycolate, sodium carbonate (or bicarbonate), sodium saccharine and sodium polyphosphate.
