The Active Ingredient Is: Selenium (Selenomethionine)

Selenium is a trace mineral essential for normal cellular processes and antioxidant protection in the body.

This form uses L-Selenomethionine, a biologically active and highly absorbable selenium compound delivered in hypoallergenic capsules.

What Does Selenium Do?

Selenium participates in antioxidant protection and supports immune system function as part of normal physiology.

It also contributes to the body's ability to interact with heavy metals, aiding in limiting their activity within the body.
