Natural Factors SelenoExcell Selenium 200 mcg 90 Capsules

Selenium is an essential trace mineral that supports antioxidant defenses, immune function, thyroid health, and healthy cell protection. This SelenoExcell® version uses selenium that has been naturally incorporated into nutritional yeast, creating an organically bound form that many people choose for its bioavailability.

If you've ever wondered why one bottle costs a couple extra bucks even though the label still says "selenium," this is why. Both products provide selenium, but SelenoExcell® uses an organically bound yeast-based form that many practitioners prefer because it's naturally incorporated into proteins, while the standard selenium version is simply a more economical option that still gets the job done for many people.

If you're putting together a foundational wellness, immune, or thyroid support stack and don't mind spending a little more for the premium form, this is the selenium I'd generally lean toward for building your aura.
