Selenium yeast capsules are primarily used as a nutritional supplement, with selenium as their core component, which has antioxidant properties.

Selenium is one of the essential trace elements required by the human body and offers significant physiological functions and health benefits. Firstly, selenium yeast capsules can enhance the body's antioxidant capacity by participating in the synthesis of glutathione peroxidase, helping to remove free radicals and protect cells from oxidative damage.

Selenium stimulates T-lymphocytes to produce interferon, promotes the synthesis of immunoglobulins and the proliferation and differentiation of T-lymphocytes, thereby enhancing the body's immune defense capabilities. Selenium is an essential mineral component in the synthesis of thyroid hormones. Appropriate supplementation with selenium yeast capsules helps ensure the normal synthesis of thyroid hormones and may improve hypothyroid function.

It should be noted that selenium intake must remain within a safe range; excessive supplementation may lead to selenium toxicity. Therefore, it is recommended to consult a qualified physician or nutritionist before using selenium yeast capsules to determine the appropriate dosage for individual needs.
