Dietary Sources of Calcium and Magnesium. Magnesium is farmed out of the soil much more than calcium, Dr. Dean explains. A hundred years ago, we would get maybe 500 milligrams of magnesium in an ordinary diet. Now we're lucky to get 200 milligrams. People do need to supplement with magnesium.. You can typically get enough calcium from your diet by eating nuts, seeds, deep green leafy vegetables, and dairy products. Homemade bone broth is another excellent source. Simply simmer leftover bones over low heat for an entire day to extract the calcium from the bones.
