The U.S. Food and Nutrition Board set the tolerable upper intake level (UL) for selenium at 400 mcg/day. Chinese authorities place the UL, which they term "no adverse effect level," at 819 mcg/day and the "low adverse effect level" at 1540 mcg/day. China is unique in having areas where the soil selenium level is severely deficient and other areas where the levels are toxic. The first indication of selenium toxicity is "garlic breath" and dry skin. Then the fingernails develop white patches, become brittle, and fall off. In studying the health effect of various levels of dietary selenium intakes in China, investigators found that hair and nail loss occurs when selenium intake reaches 4,990 mcg/day (J Trace Elem Electrolytes Health Dis 1994;8:159–165). These findings indicate that consuming 200–400 mcg of selenium a day to keep cancers from occurring will be well tolerated, without side effects, on top of one’s dietary intake of selenium, which in the U.S. ranges from 60–110 mcg/day (in Europe it is 11–67 mcg/day).
My vitamin D supply (one bottle) is used up.
Time to order more vitamin D and now selenium?
