Our Calcium Magnesium with Vitamin D Complex is part of our Target-Min collection, which offers blends of targeted minerals for total-body utilization.  This particular formula is made with specific free-form amino acids and uses a calcium-to-phosphorus and calcium-to-magnesium ratio of 2:1 to support calcium utilization. Calcium Magnesium with Vitamin D Complex also supports your body’s availability of calcium. Adequate calcium and vitamin D as part of a healthful diet, along with exercise, may reduce the risk of osteoporosis later in life.
