Dee, I already know what 'Mercola' says. IMNSHO, Mercola's site thrives on a contrarian POV. Perhaps those of us who are "depleted" in the vit D department have other causes to look for, such as insufficient exposure to sunlight, too much clothing when outdoors, wrong time of day, Vits A, D, calcium and magnesium-poor diet, etc. (Vegetarians are particularly susceptible to the deficiency because plant derived D is not the kind we use; even animal fats are likely to be deficient if the animals were raised in confinement with inadequate exposure to sun.) Whatever sodium laurel sulfate may do, I doubt it extracts cholesterol from the inner layers of the skin, but who knows? This may become the new thinning and cardio protocol for the 21st century; just wash your HDL's away. <g>
The amount of time necessary for the body to absorb the vit D precursors generated by exposure to sun is 30 to 60 minutes, so unless you run inside to shower right away, you're probably ok even for the cholesterol containing skin oils from the sebaceous glands (and there are more cholesterols present than those found in the sebum. BTW, the time required for the markers to show up in the blood is about 12 to 24 hours but the D is already bound to its delivery protein in about half an hour. The times of day in which the UV-B from the sun is significantly present are 10 to 2. It's the UV-B that does the conversion of cholesterol.
