What is it?

Selenium is a trace mineral needed for the production of the antioxidant enzyme glutathione peroxidase. It is primarily needed for immune system health; antioxidant protection; liver health; heart health and joint care; thyroid hormone production, male fertility and prostate protection.

Function How it helps
Antixodant

Selenium is an important component of glutathione peroxidase, which protects cells from free radical damage. It also acts with vitamin E as an antioxidant protecting fats and cell membranes.

Detox and liver support Glutathione is needed by the liver to help elimation toxic compounds from the body. Selenium binds to mercury helping to protect against it’s toxic effects.
Cardiovascular health Selenium helps maintain the correct balance of HDL and LDL cholesterol, protects against excessive blood clotting and reduces cholesterol deposits. It also works with vitamin E to prevent oxidation of fat and cholesterol in the arteries.
