.. I saw the recommended ratio of 2:1. However, I did also find sites that made the assertion that since magnesium is not as readily absorbed as calcium, that the correct ratio would be 1:1. Also, as Bigg is pointing out, without adequate vitamin D, these minerals will not be adequately absorbed.
I don't think it's good when different sites give this kind of ratio, without any explanation, why there is this ratio and not the other, and also without any explanation how to adjust it. It is not good to use this ratio without any adjustment - for example thals need more calcium and more magnesium than ordinary people, but how does this change the ratio? How much more of any particular microelement?
Calcium, magnesium and potassium are for sure very difficult to balance (I mean really balance, not just make blood results look good) - just to mention a few things that have influence:
- calcium: PTH, calcitonin, vitamin D, sodium intake (when you eat a lot of sodium - ordinary salt - it has direct on calcium level, this method is used in fighting hypercalcemia, they give salt solution), balance with phosphorus ....
- magnesium: misleading blood test results (with calcium it is different - there is the method to measure bone density), absorbability issues...
- sodium ...
- potassium ...
For now it is impossible to take into account all the factora and the ratio is kind of useless.
Maybe if somebody knew how to take all of this into account, we would know how to treat some cases of resistant ostheoporosis, instead of poisoning people with not very nice drugs or even strontium.
Unfortunetely I myself do not know.
After my own experience, I would be very hesitant to cut vitamin D intake without a test to show that the level is in range.
Oh, no I was tested in the meantime - my vitamin D level was 36 - so it is in normal range anyway. But since then I was not tested, because this last test confirmed entirely the number of vitamin D IUs I have to take to raise blood level to a particular level. Such calculations (as decribed in previous post) may be helpful in assessing when you have to do the next blood test and if the dose you get is sufficient. One more thing to know about vitamin D is that 400 IUs are used up daily. So these 400 IUs have to be
subtracted from the dose. I did not want to make the things more complicated in the last example, but when I got 500 IUs a day, this really meant 500 - 400 = 100 IUs a day, so supplementation would have to last for 5 000 days = 14 years. This explains, why small doses are completely uneffective. Of course daily usage may be only 300 IUs, but you get the idea.
I am a little afraid about getting too high vitamin D level due to my hypercalcemia and problems that are described as a consequences of high vitamin D - mainly calcification of arteries and other things. How can this be counteracted?
