Question

Are the effects of selenium deficieny long-lasting or correctable?

Answer 1

selenium deficiency is pretty unusual in normal healthy people. unless a real doctor suspects a deficency or think you are at risk for a deficiency and need to supplment, chances are youre fine. most people get plenty in their diet, and most mutlivitamins supplement it as well. probably no need to take extra.

Answer 2

Hopefully such a deficiency can be corrected with supplements.

If you consume 2 Brazil nuts every day you are getting 200 mcg of selenium every day.  Most health authorities recommend no more than 100 mcg per day .  The toxic dose is generally regarded as being 300 mcg per day.

Perhaps you might want to investigate a web search for "brazil nuts" + selenium.
