Experiences with selenium supplementation?

Curious, why not just eat shrimp?

Also, isn't beef kidney high in selenium?

I tend to notice an increase in anxiety from thyroid, and in case this isn't a transient effect I wanna know if selenium plays a role. It's just curiosity.

Tried it, noticed nothing.

Same here. Also, it smelled horrible - like pus. I think that was the Thorne one.

2 brazil nuts/day will provide around 200µg and the selenium is balanced with other nutrients. It's effectively absorbed.

Thanks Bukowski!!

I've been meaning to buy them - brazil nuts.

brazil nuts are the worst though. I don't know how people eat them.

Don't like em? Taste fine imo.

When asked about one brazil nut daily for selenium, Ray replied: "The proteins and fiber in nuts can cause intestinal inflammation." Could it really be that harmful to eat just one nut daily?

Maybe he means for some people it can. I've not noticed any issues with digestion and daily brazil nut or two. Though I did stop because I figured I was getting enough selenium from milk and oysters. Lately I've even been eating brewer's yeast and I think that may have a helpful bit of selenium too.

2 nuts (10g) would contain 0.8g fiber and 1.4g protein. Put into relation to other foods (1.8g fiber in 100g potatoes or 2.2g fiber of 100g raw oranges), I don't think it is any issue.

I experimented with Life Extension's Super Selenium Complex @200mcg/day. It raised my pulse that was not responding to thyroid supplementation earlier.

Selenium apparently is important if you are high dosing iodine.

Paul Jaminet:

Selenium deficiency causes an intolerance of high iodine.
Iodine intake via seaweed is accompanied by thyrotoxic metals and halides.
Sudden increases in iodine can induce a reactive hypothyroidism.

All three of these negatives can be avoided by supplementing selenium along with iodine, using potassium iodide rather than seaweed as the source of iodine, and increasing iodine intake gradually.

And iodine may be important in protecting the thyroid from the effects of goitrogenic foods:

I read somewhere that the Japanese diet provides on average 12mg (not micrograms) of iodine per day along with adequate amounts of selenium.

There are widely documented deficiencies in soil and serum of people where I live, so I supplement it either way, only on some days though.

what about iodine in salt if it's used a lot while cooking?

You need selenium regardless of your iodine intake. At "normal" levels of intake (just what you get from salt) 50-100 mcg per day (from food) should be enough. If you are using Lugol's or Iodoral's I would aim for more (if necessary supplementing 100-200 mcg per day).

Mild improvements in body temperature (higher earlier in the day) and energy.  

Maybe cognitive improvement.
