Seems great

Everything as expected. I bought it to support my thyroid as I was feeling tired despite my medication. I’ve taken this supplement daily for less than a month, but so far it seems everything is as expected and I am slowly feeling the benefits. The package is practical and the shipment arrived in time.

Works

This is my favorite selenium supplement. I take it only twice per week as I only want to supplement my diet. Had a blood test done recently and it came back significantly higher.

Good Selenium Supplement

Source Naturals provides a good, organically bound form of selenium. More specifically, the selenium-the only functional ingredient- is derived from yeast, and is good quality. I like that the product contains 200 mcg of selenium per tablet, and the tablets are small. This is a great alternative to the common methionine form of selenium.
