Selenium: Benefits, Uses, Dosage & Complete Guide

Selenium is an essential trace mineral that plays a vital role in antioxidant protection, thyroid function, immune health, and cellular function. It helps protect the body's cells from oxidative stress while supporting normal metabolism and overall well-being. Since the body cannot produce Selenium, it must be obtained through food or dietary supplements.

Selenium is naturally found in Brazil nuts, seafood, meat, eggs, whole grains, and dairy products. It is also available as a dietary supplement and is commonly included in multivitamins, antioxidant formulas, and thyroid support supplements.

As awareness of preventive healthcare continues to grow, Selenium supplements are becoming increasingly popular in Pakistan among individuals looking to support immunity, thyroid health, and healthy aging.
