How long will it take me to make myself REALLY sick? Vitamin D question. x-post

Since magnesium is required for the conversion of vitamin d into its active form, it's also true that taking vitamin d may not raise Vitamin D Blood Levels in those who are magnesium deficient!! Be sure that you read this again and understand this magnesium and vitamin d interrelationship:

 

 

• Magnesium is 'Used Up' when Vitamin D is converted into its active form in the blood

   

   

• Magnesium is 'Required' to convert Vitamin D into its active form in the blood

It works BOTH ways. Magnesium is not JUST depleted, but you won't convert vitamin d unless you have enough magnesium in order to allow vitamin d to BE converted!! In many cases where large doses of vitamin d are taken but the vitamin d level does not come up, both the person deficient and their doctor believe that they are having Vitamin D Absorption problems. This ends up causing:

1) A lot of fear that an underlying serious medical problem exists

 

2) Unnecessarily high dosages of Vitamin D are often taken causing worsening of the magnesium deficiency

3) Thousands and sometimes tens of thousands of dollars are spent in unnecessary medical testing to find the 'absorption' problem

4) The underlying magnesium deficiency is often never found and addressed because testing for magnesium levels is not a useful test to determine need for that nutrient
