The Active Ingredient Is: Selenium (L-Selenomethionine Form)

Selenium is an essential trace mineral that helps with normal antioxidant defences and supports immune function, and supports thyroid health.

This form, L-selenomethionine, offers high bioavailability and is the source used in this supplement to provide selenium in a readily utilised form [for daily use].

What Does Selenium Do?

Selenium takes part in antioxidant enzyme systems and supports normal immune cell function and thyroid hormone metabolism, contributing to overall maintenance of normal physiology.

Dr. Barchielli from the University of Basel found that selenium supplementation boosts immune cell activity and supports antioxidant enzyme function, aligning with EFSA and NHS guidance on nutrient roles.
