It is a common misunderstanding that calcium is the only mineral important for bone health. It is important to know that magnesium is part and parcel of the proper functioning of calcium. A deficiency of magnesium can lead to osteoporosis and an increased risk of bone fractures. This is due to four main causes.
First, bones store a lot of magnesium and a decrease in magnesium in the blood can lead to brittle bones.
Second, magnesium deficiency can cause a decrease in calcium levels, and calcium is significant for maintaining strong bones.
Third, magnesium deficiency can drop calcitonin levels in the blood which results in reduced cellular levels of calcium in the bone leading to osteoporosis.
Fourth, magnesium is important for vitamin D absorption which is important for healthy and strong bones.
