The Active Ingredient Is: Selenium (Selenomethionine, Se-methyl L-selenocysteine, and Sodium Selenite)

Selenium is a trace mineral that contributes to normal antioxidant defences and supports immune and thyroid function through multiple forms. This product combines selenium in several forms for broad activity, alongside vitamin E to complement antioxidant protection.

The selenium forms are provided in mixed forms, which support selenium’s role in cellular protection and metabolic processes related to thyroid function and immune health.

What Does Selenium Do?

Selenium participates in the function of glutathione peroxidase enzymes, helping to protect cells from oxidative damage and supporting normal immune and thyroid activity.

Vitamin E stabilises cell membranes and helps prevent lipid peroxidation, contributing to the antioxidant network that supports cardiovascular and brain health. Scientific research suggests these roles are part of selenium and vitamin E’s collaborative antioxidant action.
