"Severe Hypercalcemia Following Vitamin D Supplementation in a Patient With Multiple Sclerosis - A Note of Caution"
In this case we are talking about a person taking additive effect of 5500 IU of cholecalciferol and 2020 mg of calcium daily.
This is almost twice the RDA for her age.
The RDA is the minimum requirement for health from all sources and we should all be aware that DIETARY calcium sources compared to supplements are better used by the body
which is why these are listed first in the details at the above link.
We should also be aware that when we increase Vitamin D status our ability to absorb calcium from food/water increases about 4 times so at the same time we need to REDUCE our reliance on calcium supplements. We should also be aware that calcium supplements are linked to increased stroke risk.
So it makes sense to REDUCE or LIMIT calcium from supplements
to no more than 600mg daily while of course ensuring the RDA for calcium is met in total with the balance coming from Food and water.
When considering calcium we have to understand the basics of how it is used by both muscles fibers and brain neurons. Calcium tenses the muscle fibre and excites the brain neurone. to counterbalance these actions we use MAGNESIUM to relax the muscle and calm the neuron. So in order to maintain that balance we need virtually as much magnesium as we do calcium. Unfortunately modern farming techniques don't ensure any of our foods now have as much magnesium as would have been the case just 50 yrs ago. It's a combination of plant breeding and fertilizer use and the fact that many crops are now faster maturing. We also have the problem that the use of HFCS (found now in many foods with various names glucose/fructose syrup) actually depletes magnesium status.
So not only do most people fall short of the
RDA for MAGNESIUM
We are almost all consuming drinks/foods containing HFCS derivatives that actually cause us to excrete magnesium faster than before.
So the problem with Hypercalcemia is NOT from the Vitamin D3, it's the OVERUSE of supplemental calcium in people who are MAGNESIUM DEFICIENT.
If we want to prevent people having too much calcium in the blood we need to ensure they are only obtaining the RDA for calcium and not consuming more than is necessary or desirable and that this is balanced by at least the RDA for magnesium and they aren't consuming (mainly drinking fizzy drinks like Coke or energy drinks sweetened with HFCS or it's pseudonyms) It also helps to keep calcium where it should be stored in bones, by checking Vitamin K sources. Do remember vitamin D and Vitamin K are fat soluble vitamins so consuming a low fat diet may increase deficiency in fat soluble vitamins.
A more accurate and honest headline should have been Severe Hypercalcemia Following Toxic Calcium Supplementation in a Patient With Multiple Sclerosis - A Note of Caution particularly for those who remain Magnesium Deficient.
