Description
"Selenium" is a supplement that supplies a vital trace mineral naturally present in soil and various foods. This nutrient is essential for thyroid hormone synthesis, directly impacting metabolism and energy production. It also aids in antioxidant defense by supporting glutathione peroxidase, an enzyme that helps neutralize oxidative stress. In addition to its role in immune regulation, selenium contributes to cellular integrity. Its continued use in dietary supplementation ensures adequate intake, particularly in regions with selenium-deficient soil.

When To Take It
Selenium can be taken at any time, as its absorption is not tied to a specific time of day.
Synergy and Antagonism
Selenium works with vitamin B3, vitamin C, and vitamin E to enhance antioxidant protection. It supports thyroid health through its synergy with calcium, iodine, and zinc. Selenium also pairs with copper, iron, potassium, and manganese to reinforce immune function. However, vitamin A and heavy metals (aluminum, cadmium, mercury, lead) can interfere with its benefits.
