Bone & Joint
Both magnesium and calcium control the density and brittleness, or flexibility, of bones, says Nan Kathryn Fuchs, PhD, Blackboard chalk is calcium carbonate. Drop it and it breaks easily. Ivory is a combination of calcium [and] magnesium. Drop a piece of ivory and it bounces without breaking. Your bones can be more like chalk or more like ivory.
Calcium & Magnesium work in conjunction with each other. When our bodies lack Magnesium, Calcium levels can get too high causing calcification of our organs, making bones porous & brittle and our joints can deteriorate. Mg12 supplements balance Calcium & Magnesium in the body to alleviate build up in your arteries, pain and discomfort in your joints & bones due to osteoporosis, arthritis, calcium deposits, bone spurs and other bone & joint ailments.
