Promotes Healthy Cells by Avtivating Antioxidant Glutathione
Selenium is a trace mineral which supports healthy activity within your immune system, functions as an important part of the potent antioxidant glutathione, and is necessary for good thyroid health. This formula uses SelenoPure high, yeast free selenium for ultimate immune support. It is chelated to ensure better utilization by the body, as well as rapid absorption.
Selenium and Glutathione
Our bodies use Selenium to produce glutathione peroxidase, which is a part of the body's natural antioxidant defense system, manufactured in the liver. It works with vitamin E to prevent cell membranes from being damaged by harmful free radicals, and detoxifys harmful compounds so they can be removed from the body. Some glutathione is released into the bloodstream, where it helps to maintain the integrity of red blood cells while protecting your immune system's white blood cells as part of the body’s natural defense.
To avoid the risk of toxic levels of Selenium building up in your system, avoid taking high doses (900 mcg or more at one time, or 600 mcg daily for an extended period of time). Also be sure to take into account the amount of selenium you're getting from foods such as seafood, and whole grains, oats, and nuts.
Research Suggests that Selenium Supports Immune Health
Selenium is a requirement for a well-functioning immune system, and in a study published in the American Journal of Clinical Nutrition*, researchers investigated the effects of beta-carotene and Selenium supplementation in patients who had deficiencies of selenium and vitamin A. The researchers measured the blood enzymatic antioxidant system, including glutathione and Selenium concentrations. The placebo group consisted of 18 patients who received no supplementation, the beta-carotene group comprised 13 patients receiving oral beta-carotene, and the selenium group was composed of 14 patients receiving oral Selenium. All groups were studied for one full year, and results showed glutathione activity increased significantly after three to six months of supplementation. The researchers stated that glutathione plays an important role in the natural enzymatic defense system in detoxifying hydrogen peroxide in water, therefore Selenium supplementation could be of great interest in protecting cells against oxidative stress.
