What is the best way to get proper intake of selenium? Right now, my only real food intake is wild scallops, but I doubt that I am getting enough, especially since many have suggested that I supplement because of low thyroid function.
I am looking at purchasing Source Naturals Selenium. This is "organically bound" using yeast, but I see that there are some options that are yeast free. Does it matter which one I choose? Does the yeast factor help with absorption (assuming no problems with yeast)?
Regarding high-selenium yeast versus non-yeast selenium:
I get my selenium from food (e.g., eggs, meat, produce). I live in NYC and buy a lot of my food from NJ or the Hudson valley, both of which have soils with decent concentrations of selenium.
If you do supplement, I would use a lower dose since there isn't much, or really any, good data for the higher doses and interactions are more likely (iodine, etc). I like New Chapter's brand (and used to use it sporadically). I stopped because it is 100mcg, which is still kind of high. Ideally, I would try to try to find a natural food brand that delivers no more than 50mcg.
I supplement and here's why. (1) Not a big enough fan of Brazil nuts to make them a regular part of my diet, and (2) I discovered I was probably Se deficient quite by accident. I don't recall why I decided to supplement, but it magically cured my insomnia that I always thought was just stress related. But how could I be Se deficient when I went on sushi kicks and eat a lot of Se-rich seafood? Well Mario (who has guest blogged on PHD) mentioned that the mercury levels in seafood might be countering the Se.
My thoughts on supplements are that ideally you get most micronutrition from foods, but sometimes you just can't. And sometimes there's enough of a compelling reason to get more than the minimum based on studies or personal experience. I make it a habit never to start/stop more than one supplement at a time so that my personal experiments can be as helpful as possible. Then, in the end, if a supp falls in the "can't hurt" category -- and I include the financial hurt in that equation -- I'll use it.
