Potassium bicarbonate supplies potassium, an electrolyte your body needs, plus bicarbonate to buffer acidity. It helps your system handle the acid load from a modern diet. People also reach for it when potassium dips, whether from medication or other causes. Take it with food to keep your stomach comfortable.
Too much potassium can become dangerous fast. Skipping ordinary caution is how levels climb into unsafe territory. If your kidneys do not work well, or you take blood pressure drugs like ACE inhibitors, ARBs, or potassium sparing diuretics, get a doctors input before you start. Do not use this supplement with Addisons disease or advanced kidney disease.
