Most people are deficient in selenium.

Especially in the midwest around the Great Lakes. Just not that much in the soils in this area. Supplementation is imporrant, selenium is a very important mineral.

the stinky mineral- just started taking it 2 weeks ago-

I’ve read somewhere (Mercola?) that one nut a day will do it for your selenium requirement. I keep them in the fridge since that means a bag lasts a long time.

[faucetman]

I take it every day.

200 mcg

The first one I got would just stink when I’d open the bottle and also burp it up. I just bought a brand that doesn’t do either.

[FrankRizzo890]

Via an OTC supplement? If so, would you mind sharing what you take?

Bronson Selenium 200 mcg

Most Brazil nuts in America’s come from Bolivia. Bolivian Brazil nuts are lower in selenium, but also lower con radium and barium, according to this study: https://www.researchgate.net/publication/223715605_Concentrations_of_selenium_barium_and_radium_in_Brazil_nuts

Heh, maybe there’s more to seniors eating all those prunes than just the digestive benefits.

Are Bronson Vitamins ‘Standardized Formula’s’???

Brazil nuts contain very high amounts of selenium (68–91 mcg per nut) and can cause you to go over the upper limit if you eat too many. Getting too much selenium over time can cause the following: Garlic breath. Nausea

Thank you for sharing that critical information. Very few people seem to be aware there are limits to what should be consumed with beneficial supplements. Zinc can poison you above 50 mg, vitamin D has no recognized benefits beyond 4,000 icu and so on, vitamin A becomes toxic on overdose.

I was a vet show called The Incredible Dr. Pol and he often gives cows selenium when they have weak muscles.

You're welcome

Years ago I read about a guy who drank so much carrot juice that he got cirrhosis of the liver and died.

I've been posting this about Vitamin D for years now:
