Calcium is the most abundant mineral in the body and is vital for several bodily functions, especially bone health. Magnesium is also essential for healthy bones, as well as for muscle function, and a healthy heart. Vitamin D plays a crucial role in maintaining healthy bones, helping the body absorb calcium and magnesium. Part of our Target-Min collection, which offers blends of targeted minerals for total-body utilization, our Calcium Magnesium with Vitamin D Complex is formulated with a calcium-to-phosphorus and calcium-to-magnesium ratio of 2:1 to support calcium utilization.
