Re: OT: Vitamin D levels chart
"Sulfur effects cell permeability, this effects
Iodine transport.."
-yes I have noticed some noticeable improvements after I started sulfur supplementing. Could be a key when one are stuck / get to a plateau where not much seems to happen.
It also have a say in vit D convertions / utilization.
The best explanation of it I have found so far it Seneff`s:
"I believe, first of all, that the distinction between vitamin D3 and vitamin D3-sulfate really matters, and also that the distinction between vitamin D2 and vitamin D3 really matters. Vitamin D2 is the plant form of the vitamin -- it works similarly to D3 with respect to calcium transport, but it cannot be sulfated. Furthermore, apparently the body is unable to produce vitamin D3 sulfate directly from unsulfated vitamin D3 [Lakdawala1977] (which implies that it produces vitamin D3 sulfate directly from cholesterol sulfate). I am not aware of any other food source besides raw milk that contains vitamin D3 in the sulfated form. So, when studies monitor either vitamin D supplements or vitamin D serum levels, they're not getting at the crucial aspect for heart protection, which I think is the serum level of vitamin D3 sulfate."
