The Primary Element Remains Selenium (L-selenomethionine)

Selenium is a vital mineral that assists in normal thyroid function and antioxidant defence.

This form, L-selenomethionine, is a naturally occurring, highly bioavailable organic selenium source and is widely used in vegan capsules to help uptake within the body.

What Selenium Does?

Selenium participates in thyroid hormone metabolism and supports immune function, while contributing to antioxidant defences that guard cells from oxidative stress. This combination helps daily metabolism regulation and vitality.

Dr. Johnson from Harvard University found that selenium helps with normal thyroid function and immune health, aligning with EFSA guidance on essential trace minerals.
