Calcium ,magnesium or who is best taken as crucial ,
Taking calcium with magnesium, vitamin K, and vitamin D is IMPERATIVE if you actually want to absorb the calcium that you take. Magnesium and Vitamin D work together in order to absorb calcium in the intestines and Vitamin K regulates where the calcium goes.
Calcium, just like it is in your bones, prefers to be in crystal form. But in your blood, this can cause severe problems such as Kidney Stones and even kidney failure. But magnesium keeps calcium in 'solution' in the blood. Calcium in crystal form just simply can't be absorbed through your intestinal tract easily, but adding plenty of magnesium makes sure that your calcium STAYS in 'liquid' form in your blood.
Next, vitamin D is put up to the task of getting the calcium absorbed by the intestines. You can take all of the calcium that you want, but almost none of it will get absorbed if you don't have sufficient vitamin d. Sufficient Vitamin D Levels can increase your absorption of calcium by 5 times! That means that you can take 1/5 the amount of calcium and still ABSORB the same amount. That's why it's not the CALCIUM that's important, but the calcium with magnesium,so which one is demanding?
