VITAMIN D NEWS HEADLINE - VITAMIN D AND TOXICITY
Thinking of taking massive doses of vitamin D? In the 1930's doctors ran studies where they gave subjects 200,000 to 13.5 million IU's of viatmin D per day. However, these doses are too high according to studies summarized by Dr. John Cannell, head of the Vitamin D Council (www.vitamindcouncil.org). In his August 2010 Newsletter entitled "Gary Null and Vitamin D Toxicity," Dr. Cannell indicates that these massive doses caused anywhere from no adverse effects, toxic effects, to deaths.
Dr. Cannell's August 2010 newsletter is available at: http://www.vitamindcouncil.org/releases.shtml. Dr. Cannell is a proponent of vitamin D, but he clearly states on his website that toxic levels are not safe. This summary of vitamin D toxicity is a must read for anyone who is considering taking massive doses of vitamin D.
In contrast, in the newlsetter, there is interesting information about dramatic improvement of patients with rheumatoid arthritis, asthma, and multiple sclerosis as well as information that indicates that some people have a resistance to vitamin D and that increasing the intake substantially can cause the body to start absorbing it. Perhaps one size does not fit all -- we all have a different genetic make up and we perhaps all need different levels of vitamin D depending on factors such as our age and health.
