The Role of Selenium in Cancer Supportive Care
Helping you understand “how selenium can help maintain your immunity and antioxidant protection during treatment”
Selenium is an essential trace mineral that plays a critical role in cancer supportive care, as it is a key component of antioxidant enzymes (such as glutathione peroxidase), helping to reduce treatment-induced oxidative stress and inflammation.
Cancer patients often develop selenium deficiency due to treatment consumption and impaired intestinal absorption, leading to weakened immunity, increased fatigue, and greater cellular damage.
Selenium is not an “anti-cancer mineral” but serves as supportive care, helping patients better endure the burden of chemotherapy, radiotherapy, or targeted therapy, maintain tolerance, and improve overall quality of life.
