Selenium supplements with the fewest additives

Selenium has been one of my most-requested pages, but until Chris Masterjohn's podcast on it, I didn't understand it enough to be comfortable making suggestions. I can't speak highly enough of that episode if you're considering selenium supplementation, and I've put up my visual notes (and information about getting a selenium blood test) on my other site.

After looking through the popular selenium brands, I'd suggest Solaray's. They have more excipients than I'd prefer, but they're better than the other brands tested tested by ConsumerLab for selenium/lead levels when factoring in my preference for straight L-selenomethionine. I don't necessarily mistrust other brands though (most did well in testing), it's just the product I'd lean towards:

Name Ingredients
Solaray Yeast-Free Selenium (200mcg Gelatin Capsules)
Available on iHerb

Selenium (as yeast-free L-selenomethionine), whole rice concentrate (including the bran, germ and polishings), gelatin capsule, cellulose and magnesium stearate.

Dosage

As alluded to in that podcast, the standard 200mcg amount in most of the products is a pretty high dose, and some of the brands even suggest taking it 1-2 times daily.

I'd suggest dosing it very conservatively, and guesstimating the intake you get from food first with a tool like Cronometer (after taking into account the variability issues discussed in the podcast that I've now mentioned entirely too many times). Even better would be doing some blood testing, although it's on the order of $70+ per test.

My miscellanious selenium notes

Some things to note about selenium that I'm only aware of thanks to a smartypants person cloaked in the mysterious forum name Amazoniac:
