High dose selenium significantly improves my fatigue levels, and noticeably reduces my brain fog. I have consistently found selenium to be the best single supplement or drug I have tried for ME/CFS. I found that it requires a high(ish) dose of 400 mcg of selenium each day before these benefits manifest.The best form of selenium to take is yeast-free selenomethionine, as selenomethionine the best absorbed form of selenium.Selenium must be taken on an empty stomach, to ensure it is properly assimilated.f I cease taking my daily dose of 400 mcg selenium, within about 3 or 4 days of stopping, my fatigue and brain fog will begin to get worse again. If you want to maintain the increased energy and cognitive abilities it provides, one should take selenium on a daily basis.
