As many of know by now the US Institute of Medicine (IOM) published a report this week stating that people do not need to take vitamin D supplements. They also warned that taking 10,000 IU or more per day could be toxic without producing any evidence to support that assertion. These recommendations fly in the face of many recent scientific studies that have shown the relationship of vitamin D deficiency to cancer, heart disease, diabetes, depression, and immune system problems. This evidence is so convincing that I advise all of my patients and my own family to take vitamin D3 supplements during the winter months, and to make sure their blood levels of vitamin D are adequate.
The independent Vitamin D Council quickly published a response to this report urging consumers to continue taking vitamin D supplements and condemning the IOM for suppressing testimony from recognized vitamin D experts. You can view their response here.
Why would a prestigious committee make these sweeping statements discounting the mounting evidence that vitamin D is essential to maintaining good health? Many voices are crying foul play and accusing the committee of conspiring with the pharmaceutical industry to keep people sick. See the response of health editor Mike Adams.
I agree with the recommendations of the Vitamin D Council that adults (including pregnant women) should take 5,000 IU of D3 per day, babies should have at least 400 IU, and older children 2,000 IU.
Dr. Joseph Mercola has an excellent one hour lecture on the benefits of vitamin D at his website.
