Selenium a Day ?

"The need for your selenium dosage from supplements is more subtle. Blood testing does not give adequate information about need for selenium, and unlike Vitamin B12 Supplements which have few, if any, toxic effects even at massively high doses - you CAN take too much selenium and impair your health."
...
"While there is no clear cut answer to this because of varying levels of selenium in water and soil in each part of the world, one study reported early signs of selenium toxicity at dosages as low as 400 mcg per day. And the benefits of selenium supplementation don't seem to require dosages that high, so it's safe to say that it is unnecessary and potentially unsafe to take dosages of 400 mcg per day or more long term. "
...

"In the short term, there have been many studies showing benefits of taking 200 mcg per day for many months at a time without causing selenium toxicity. But there is no consensus as to how long this dosage can be continued safely. And again, the safety of these dosages will depend upon the levels of selenium that occur naturally in your food and water as well. So a dosage that is safe for one person may not be safe for another person who lives in an area with high selenium levels or eats the plants grown in an area with high selenium levels.

So, from a selenium safety perspective we can say that you should NOT take selenium at dosages of 400 mcg or higher unless a doctor specifically tells you that you should, otherwise you are putting yourself at risk for Selenium Overdose, and there is just simply no reason to put yourself at risk when much lower Dosages of Selenium can provide potential health benefits with minimal risk.

we dose our lambs with a selenium supplement right after birth. It prevents "White Muscle disease" in newborn lambs. We are in a selenium deficient area. Our soils are quite acidic so we compare our stock and crop needs with the soil analyses.

Why not just eat food?

er, I don't mean the lambs should..

Regarding Selenium supplementation to diet, according to expert source Web-MD:

"Most of the selenium in the body comes from the diet. The amount of selenium in food depends on where it is grown or raised. Crab, liver, fish, poultry, and wheat are generally good selenium sources. The amount of selenium in soils varies a lot around the world, which means that the foods grown in these soils also have differing selenium levels. In the U.S., the Eastern Coastal Plain and the Pacific Northwest have the lowest selenium levels. People in these regions naturally take in about 60 to 90 mcg of selenium per day from their diet. Although this amount of selenium is adequate, it is below the average daily intake in the U.S., which is 125 mcg.


Selenium is used for diseases of the heart and blood vessels, including stroke and “hardening of the arteries” (atherosclerosis). It is also used for preventing various cancers including cancer of the prostate, stomach, lung, and skin.

Some people use selenium for under-active thyroid, osteoarthritis, rheumatoid arthritis (RA), an eye disease called macular degeneration, hay fever, infertility, cataracts, gray hair, abnormal pap smears, chronic fatigue syndrome (CFS), mood disorders, arsenic poisoning, and preventing miscarriage.

Selenium is also used for preventing serious complications and death from critical illnesses such as head injury and burns. It is also used for preventing bird flu, treating HIV/AIDS, and reducing side effects from cancerchemotherapy.

How does it work?
Selenium is important for making many body processes work correctly. It seems to increase the action of antioxidants."
