Too much Vitamin D???

Here's an interesting article on Vitamin D by Chris Materjohn that discusses whether supplementing may cause PROBLEMS...

 

If you are taking Vitamin D, please make sure you have a 25(OH)D blood test to see what your level is (even if you're not supplementing it is a good idea to have it checked).

 

ARE SOME PEOPLE PUSHING THEIR VITAMIN D LEVELS TOO HIGH?

Has science proven that the minimal acceptable blood level of vitamin D, in the form of 25(OH)D, is above 50 ng/mL (125 nmol/L)?  No.  If you've been trying to maintain your levels this high because you thought this was the case, I'm sorry to break the news.  There is, on the contrary, good evidence that 25(OH)D levels should be at least 30-35 ng/mL (75-88 nmol/L).  Much higher levels may be better, or they could start causing harm, especially in the absence of adequate vitamins A and K₂.   Once we leave the land of 30-35 ng/mL, however, we enter the land of speculation.

The bottom line is: "...if you are trying desperately to maintain year-round 25(OH)D status between 50-80 ng/mL using vitamin D supplements, you have entered the land of speculation.  Enter at your own risk."
