Proper testing is essential for Magnesium & “Vitamin” D! and if people would have started at this point instead of running in circles and behaving like “MS”-ologists the thread would have needed most likely a lot less posts to get to this point, wouldn't it? ....better crawling back in my FB-hole now.

How to test for Vitamin D properly:
Want to find out the true status of your active “Vitamin”-D and bypass BIG-Pharma ("Vitamin-D Council") brainwash?
No problem! To avoid the latest $$$pharma scam$$$ paired with the stupidity of the medical establishment please ask for these 4 blood tests before you take an insanely high dosage of a synthetic hormone called “Vitamin D”.
The 4 basic blood tests are:
1. Magnesium RBC (amount of Mg in red blood cell and NOT in blood serum!)
2. 25(OH)D (Storage form of Hormone-D)
3. 1,25(OH)2D3 (Active form of Hormone-D)
4. "Ionized" Calcium blood test
If test No.1 is 6.0mg/dL (this is a sufficient amount of Mg in the body tissue needed for the production of "Vit.-D" because Mg-deficiency causes Vit.-D resistance/deficiency!) and test No.3 is low, and test No.4 is low too then and only then taking supplemental "D" (e.g cod-liver oil) would be advised.
Test No.2 it's essentially a distortion of reality because low "Calcidol" (storage form) is caused by to much Calcium in the blood, which means there is too little Mg in the blood. Much better to know is the true status of your active hormone and its mineral focus Calcium. Excess Calcium is the precursor to inflammation and more excess Calcium to Magnesium is the cause of hormonal imbalances, disease & death.....
