Red_Star's comment regarding magnesium is certainly substantiated. There is controversey over calcium intake. During the 1950's the Canadian endochronologist Hans Selye wrote a book and attributed numerous problems to excessive calcium intake. I would concur with Red_Star's advice and suggestions.
I have calcification of my mitral heart valve due to magnesium deficiency. Increase your magnesium intake.
Excerpt from the article Calcification and Its Treatment with Magnesium and Sodium Thiosulfate...
"Dr. Dean makes this clear when she says in her book The Magnesium Miracle, “To understand how you can create a calcium/magnesium imbalance in your own body, try this experiment in your kitchen. Crush a calcium pill and see how much dissolves in 1 oz of water. Then crush a magnesium pill and slowly stir it into the calcium water. When you introduce the magnesium, the remaining calcium dissolves; it becomes more water-soluble.
The same thing happens in your bloodstream, heart, brain, kidneys, and all the tissues in your body. If you don’t have enough magnesium to help keep calcium dissolved, you may end up with calcium-excess muscle spasms, fibromyalgia, hardening of the arteries, and even dental cavities. Another scenario plays out in the kidneys. If there is too much calcium in the kidneys and not enough magnesium to dissolve it, you can get kidney stones.”"
