Hi, I have some questions which you might know the answers to: 1) If vitamin D synthesised and sulfated on the skin is water soluble, does that mean that it is washed out easily just with cold water? Does the same go for sulfated cholesterol, etc..? 2) Is the vitamin d3 in supplements obtained from lanolin sulfated? I would imagine it would have been sulfated when it was on the sheep, but perhaps it becomes unsulfated in processing? 3) Is the vitamin D found in oily fish, seal oil etc, sulfated in its raw state? Does it remain sulfated following cooking? Thanks.
