I've been taking 200 mcg daily of a selenium supplement that says it is L-Selenomethionine that my doctor instructed me to take to help with hypothyroid problems. I don't know how it compares to photographic selenium. Hope that is helpful. Carol

Morning All, I need to get over the following stumbling blocks so a couple of quick and short questions if someone would be so kind... (1) Is the Selenium taken as a supplement in the form of a sulphide, selenate or selenite? Or perhaps something entirely different? If 'something different', maybe a brief explanation of the difference. (2) Does the Selenium as used in photography have any similarities to the supplemental form of Selenium?...Yes/No/Don't know. If 'No', maybe the non-similarities could be explained a little. I'm having some difficulty finding appropriate definitions of the various forms of Selenium with relation to its use in a supplemental form. Thanks...N.
