What the brand says

Potassium (K) in the form of K+ is the most essential cation (a positively charged ion) of the cells. Its high intracellular concentration is regulated by the cell membrane through the sodium-potassium pump. Most of the total body potassium is found in muscle tissue. Total body potassium has been used as a measure of lean body mass, of muscle mass, or (more accurately) of cell mass. Because of its association with the metabolizing, oxygen-consuming portion of the body, a decline in total body potassium is usually interpreted as a loss of muscle mass due to a catabolic condition. IMPORTANCE: Works with sodium to regulate the body's waste balance and normalize heart rhythms; aids in clear thinking by sending oxygen to the brain; preserves proper alkalinity of body fluids; stimulates the kidneys to eliminate poisonous body wastes; assists in reducing high blood pressure; promotes healthy skin.
