Vitamin D, new warning

[Guest guest]

I don't think I believe this but wanted the groups thoughts on this

report. I found this link on the Amazon board, I think they use

iodine.

Its a long articule but here is a part of it. Please read it an give

your oppinions. I personly believe we need more sun an fresh air but

who knows. I'm confused because I found the amazon board from a link

to the iodine for breast cancer board. There i found a link to a

board that believes most deseases are caused by bacteria. If I read

it right they believe that supplements feed the deseases. I may just

not understand. That sounds like the old school of thought to me.

Most alarming, however, is the fact that the medical community is

currently oblivious to yet another public health disaster of epic

proportions - one that is affecting the entire population. In an

effort to curb chronic disease, well-intentioned researchers are

promoting vitamin D, a substance that, according to recent molecular

modeling research, can act as an immunosuppressive steroid. Studies

which incorrectly interpret the reason for low vitamin D in patients

with chronic disease have been seized upon by the media, and form the

basis of massive advertising campaigns – which, along with ill-

informed recommendations by doctors and researchers, have created a

perfect storm of misunderstanding and bad advice.

What follows are fourteen pieces of a puzzle that, when complete,

reveal a massive misunderstanding of the actions of vitamin D.

Let's start with this fact: the vast majority of doctors touting the

benefits of vitamin D are not aware of discoveries made by

researchers in the field of molecular biology, which have clearly

shown that the " vitamin " D derived from diet and supplements is not a

vitamin, but a steroid with immunosuppressive properties when

elevated.2

There are several forms of vitamin D. The form of vitamin D we get

from food, diet, supplements and sun exposure is called D3. D3 is

converted by the kidneys into 25-D, which functions as a steroid.

1,25-D, the activated form of vitamin D, functions as both a steroid

and a hormone. It is produced inside various types of cells,

including those of the immune system and the kidneys, as well as in

response to sunlight. In healthy individuals, the kidneys continually

convert 25-D into its active form, 1,25-D.34

According to a paper published by the Institute of Biomedical

Research in Birmingham, England, " The active form of vitamin D, [1,25-

D] is a potent immunomodulatory seco-steroid " meaning that it is a

steroid-like molecule which is able to control the activity of the

immune system. " 5

Molecular modeling has shown that the hormonal 1,25-D form binds and

activates the Vitamin D Receptor. The Vitamin D Receptor plays a

fundamental role in the body. It transcribes 913 genes, and

researchers at McGill University in Canada just released a paper

saying it may actually transcribe 27,091.6 But, the Vitamin D

Receptor also performs another critical function – it serves as a

switch that regulates the activity of the innate immune system.789

A molecular model comparing the structure of 25-D and of 1,25-

D10According to recent molecular models, the steroid 25-D binds the

Vitamin D Receptor and affects the activity of the immune system as

well, but in a manner opposite to 1,25-D. When the steroid 25-D binds

the Vitamin D Receptor, it decreases the activity of the receptor,

causing the innate immune system to slow down and shut off. This

effect begins around 20 ng/ml and gradually increases with higher

levels of 25-D, until the VDR becomes completely blocked.11
