I chose to pair selenium with vitamins E, A and C rather than treat it as a stand-alone mineral. That combination gives the formula a stronger antioxidant framework while still keeping thyroid support at its core.

The Science Behind Selenium + EAC +

Selenium is an essential trace mineral involved in normal thyroid hormone metabolism and antioxidant defence. It is required for selenium-dependent enzymes, including glutathione peroxidase enzymes that help protect cells from oxidative stress.
Vitamin E is a fat-soluble antioxidant that helps protect cell membranes, vitamin C contributes to antioxidant defence and collagen formation, and vitamin A supports normal immune function, vision and tissue health. Together they create a broader antioxidant matrix around the selenium component.

Safety & Who It's For +

For optimal absorption, take with a meal that contains healthy fats. Do not exceed the recommended dose.
