So whats the point of measuring non active forms of D toxin in your blood?
Just because I have a gallon of gas doesn't mean I get to drive a Ferrari...
And yes unconverted VitD is a rat poison.
Where is the measurement of '1,25 dihydroxylcholecalciferol'? How can you tell if your thyroid VitD receptors are plugged if you can't tell how much is being converted?
