WHAT IT IS / WHAT IT DOES
Selenium by Thorne®—formerly called Selenomethionine—provides 200 mcg of selenium per capsule in the form of selenomethionine.
Selenium is an essential trace mineral, meaning the body cannot produce it and it must be obtained through food or supplementation.
It serves as a mineral cofactor for important antioxidant systems in the body. Selenium is a constituent of glutathione peroxidase, an antioxidant enzyme involved in neutralizing hydrogen peroxide and lipid peroxides.
Selenium also plays an important nutritional role in normal thyroid function, including its involvement in the conversion of the thyroid hormone T4 (thyroxine) to its active T3 (triiodothyronine) form.
Thorne® combines selenium with the amino acid methionine to provide a well-absorbed selenomethionine form in a convenient once-daily capsule.

THYROID HEALTH SUPPORT
Selenium is important for normal thyroid function.
It participates in enzymes involved in thyroid hormone metabolism, including the conversion of T4 (thyroxine) into the biologically active T3 (triiodothyronine).
Because of this physiological role, maintaining adequate selenium status is an important component of normal thyroid nutrition.
Thorne® Selenium provides 200 mcg in the selenomethionine form for individuals seeking targeted selenium supplementation.
ANTIOXIDANT SUPPORT
One of selenium’s key nutritional functions is its involvement in the body’s natural antioxidant defence systems.
Selenium is a constituent of glutathione peroxidase, an antioxidant enzyme that helps neutralize hydrogen peroxide and lipid peroxides.
Through its role in antioxidant enzymes, adequate selenium contributes to protection against oxidative damage caused by free radicals.
This antioxidant activity forms part of selenium’s broader role in maintaining normal cellular health and healthy aging.
IMMUNE SUPPORT
Selenium is also involved in normal immune function.
Its roles in antioxidant defence and normal cellular processes contribute to maintaining a healthy immune response.
Thorne® Selenium provides a concentrated 200 mcg serving for individuals looking to supplement their dietary selenium intake as part of an overall wellness routine.
SELENOMETHIONINE FORM
Thorne® provides selenium as selenomethionine, in which selenium is associated with the amino acid methionine.
The manufacturer identifies this as a well-absorbed form of selenium.
This product was previously marketed under the name Selenomethionine, so customers familiar with the former product name may now find it labelled simply as Selenium.
