Buying Guide: What to Look for in a Selenium Supplement

Choosing the right selenium supplement involves more than just picking a bottle off the shelf. Here are key criteria we evaluated when reviewing NOW Supplements Selenium 100 mcg.

Form of Selenium: Yeast-Free vs. Selenomethionine

Selenium can come in different forms, including selenomethionine (often yeast-based) and sodium selenite. The NOW supplement uses a yeast-free formulation, which is important for individuals with yeast sensitivities or those who prefer a non-fermented source. Yeast-free selenium is typically sodium selenite or selenate, both well-absorbed and effective. Always check the label to ensure the form matches your dietary needs.

Dosage and Potency: 100 mcg per Tablet

The recommended daily intake for selenium is around 55 mcg for adults, but many supplements offer 100 mcg to cover dietary gaps. NOW Selenium 100 mcg provides a moderate dose that is safe for long-term use. You can take one tablet once or twice daily with food. This flexibility allows you to adjust based on your individual needs without exceeding the tolerable upper limit of 400 mcg per day.
