Potassium is the third most abundant mineral in the body. Roughly 98% of the Potassium in our body is found intracellular, which helps regulate fluid balance, muscle contractions and nerve signals. A high Potassium diet can help reduce blood pressure and water retention, prevent osteoporosis and kidney stones and protect against stroke. Potassium is also used as an acidity regulator, buffering agent, flavor enhancer and replacement for sodium salts.
