An Australian survey found the concentration of selenium is just above the nutritional adequacy level. It's thought to be important for liver, thyroid, heart and immune function and there's also some evidence that selenium supplementation reduces the risk of prostate cancer. I am taking Solaray, Selenium, on a daily basis and my last blood results have shown very good results.

repeated purchase few times with this. easy swallow capsules. no odour smell. good as supplement for whole body health as daily essential. less tired . controlled sore throat and running nose . feel that I have stronger health now than before 😃

I take selenium with zink with other supplements to support my Hypothyroidism. It was packaged good and very fast shipping. I would recommend Iherb to everyone. Thank you

very good as supplement for whole body health. i recommend it.

Very convenient capsule form, easy to swallow. Good dosage for every day. There are no bad ingredients in the composition - this is a plus!

This is an easy and convenient supplement product! Also the price is lovely.

Potent formula! Selenium has so many benefits that I decided to purchase it separately from multivitamin.

Seems to be working well, I used to consume Brazil nuts, this product costs less and also contains fewer calories.

Thanks for quick delivery. High quality product. I recommend to buy.

Solaray products are all very efficient and valuable. I use also niacinamide and I'm satisfied!!
