Each serving of Ultimate CAL provides 230 mg of calcium plus key mineral co-factors (magnesium zinc potassium and boron) to promote calcium uptake. Calcium is essential for healthy bones and teeth as well as healthy cardiovascular and nervous system function. Although calcium is the most abundant mineral in the human body, we also need other trace minerals for its optimal absorption and retention. Ultimate™ Cal® provides 460 mg of calcium per serving plus trace minerals essential for good bone health, including phosphorus, magnesium, zinc, potassium, and boron. It’s the ultimate choice for anyone concerned about getting proper amounts of calcium.
