A June, 2010 study by researchers at Johns Hopkins University revealed that many over-the-counter Vitamin D supplements did not contain the claimed Vitamin D content as stated on the label. (The FDA does not regulate that). The mean concentration for 10 over-the-counter Vitamin D pills tested was only 33% of the stated amount!

Would you feel ripped off?
This begs the question for anyone that is taking Vitamin D on a daily basis to help recover from an autoimmune disease: Does the pill you take actually contain the stated concentration of Vitamin D?
