Good Selenium Supplement
Verified purchase
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.

High quality selenium without methionine
Verified purchase
This selenium supplement is without methionine, which is important for me since I don't want any other amino acids causing a dysbalance. The small size of the tablets makes them easy to swallow. The dosage is great for daily use and for anyone who has a selenium deficiency this is a great price to amount ratio.

Works
Verified purchase
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.
