Magnesium, calcium, vitamin D3 and vitamin K2 all work synergistically with one another. Excessive amounts of calcium without the counterbalance of magnesium can lead to a heart attack and sudden death, for instance. Research on the Paleolithic or caveman diet has shown that the ratio of calcium to magnesium in the diet that our bodies evolved to eat is 1-to-1.11Americans in general tend to have a higher calcium-to-magnesium ratio in their diet, averaging about 3.5-to-1.
If you have too much calcium and not enough magnesium, your muscles will tend to go into spasm, and this has consequences for your heart in particular. “What happens is, the muscle and nerve function that magnesium is responsible for is diminished. If you don’t have enough magnesium, your muscles go into spasm. Calcium causes muscle to contract. If you had a balance, the muscles would do their thing. They’d relax, contract, and create their activity,” Dr. Carolyn Dean explains.
When balancing calcium and magnesium, also keep in mind that vitamins K2 and D need to be considered. These four nutrients perform an intricate dance together, with one supporting the other. Lack of balance between these nutrients is one of the reasons why calcium supplements have become associated with increased risk of heart attacks and stroke, and why some people experience vitamin D toxicity. Part of the explanation for these adverse side effects is that vitamin K2 keeps calcium in its appropriate place. If you’re K2 deficient, added calcium can cause more problems than it solves, by accumulating in the wrong places, like your soft tissue.
Similarly, if you opt for oral vitamin D, you need to take supplemental vitamin K2 and more magnesium. Taking mega doses of vitamin D supplements without sufficient amounts of K2 and magnesium can lead to vitamin D toxicity and magnesium deficiency symptoms, which include inappropriate calcification that may damage your heart.
