i am by no means a doubter of the benifits of vitamin d, but i do have an open mind, open to suggestions now i found this peice from a web site called endalldisease.com where some guy is spouting off about this doctors research that vit d suppliments are harmfull and suppress the imune system in such a way that you think you are not ill but evetually it catches up with you and 5 years later you really can be seriously ill.

some text i found in another search"

That is exactly why ultraviolet is the gold standard. It allows the body to manufacture its own vitamin D. The body will only manufacture what it needs for optimum health. Vit D supplements can be a "cr*pshoot", you may ingest too much, too little, or whatever.

The link you provided supports my statement -

-----------------------------------
Natural Vitamin D
Normally, the body receives adequate vitamin D from 10-15 minutes of daily exposure to the sun. The skin absorbs vitamin D, which it stores and utilizes as needed. Supplements, by binding to the Vitamin D receptor, block natural vitamin D hormone. Marshall’s study, which has been confirmed by other researchers, shows that even normal doses of vitamin D supplements can suppress the proper operation of the immune system and interfere with the regulation of gene expression for more than 1,000 genes.

How in the world did you come to that conclusion? Trevor Marshall, PhD makes the point that D supplements that you ingest could be harmful. He may certainly be right and he's not the only one to make that point over the years. His work supports the position that the Vitamin D your body manufactures after exposure to ultraviolet is the best for human health. Your body simply will not manufacture more than it needs. A BIG plus for non-burning exposure to ultraviolet.

Ken,

Trevor Marshall is an Electrical Engineer or Computer Science Phd; hence the the "Dr" in his name, he is not pro-UV, his protocol has you avoid all light and wear special dark glasses since he feeds you photo-sensitizing drugs off label to suppress Vitamin D receptors, and "allow" your innate immune system response to attack a particular type of virus or bacteria ( I forget which).

His theory is that Vitamin D interferes with this action and by removing it from the feedback loop he can treat the underlying cause of the disease with drugs. It is all kind of fascinating in a tinfoil hat kind of way.
