Calcium and magnesium in a 2 to 1 ratio.

Calcium is used to develop and maintain healthy bones and teeth. It also plays an important role in controlling the heartbeat and maintaining proper blood pressure. Magnesium functions primarily as an enzyme co-factor which helps in producing energy, synthesizing lipids and proteins, regulating calcium flow and parathyroid hormone secretion, forming urea and relaxing muscles. Calcium has the side effect of raising blood pressure while magnesium will lower blood pressure.
