Selenium is an essential trace mineral which functions primarily as an anti-oxidant in the body. It works synergistically with vitamin E in reducing free radical damage to cell membranes. Selenium is also associated with supporting a healthy immune system.

Selenium is antagonistic to heavy metals including lead, mercury, aluminum and cadmium and may offer protection from environmental traces of these contaminants.

Kirkman's selenium capsules utilize L-Selenomethionine as the selenium source. This is a biologically active form which is very effectively absorbed in clinical studies conducted by the Nutrition 21 Corporation. This product is hypoallergenic in that it contains no casein, gluten, wheat, corn, dairy products, artificial flavors/colors or soy.
