Cal/Mag Plus supplies the optimal balance of calcium and magnesium, plus vitamins D-3 and K-2. These powerful boosters serve to maximize absorption of calcium and promotion of its utilization. Studies have demonstrated that magnesium can facilitate bone mineralization and muscle relaxation, while vitamin D-3 is essential for optimum calcium uptake. Vitamin K-2 encourages the synthesis of proteins involved with calcium utilization, supporting its transport to muscles and bones instead of arterial walls.*
