Nelson, there are some forms of selenium. What I use is selenomethionine on the label. What do you take? thx

The selenate form of selenium is preferred because of its stability to reduction into low-bioavailability elemental selenium (by reducing agents like vitamin C) and its high biopotency in restoring selenium status. It seems that 200 micrograms a day of selenium is considered safe, although signs of selenium toxicity begin to appear after prolonged intake of 1000+ micrograms a day. Vitamin E has been shown to lower the toxicity and increase the antioxidant effectiveness of selenium, and should preferably be taken on a daily basis with selenium. A reasonable recommendation would be approximately 300-600 i.u. of vitamin E and 200- 300 micrograms of selenium daily.
