All components of the immune system require selenium,2 including macrophages and lymphocytes.

People, especially vegetarians, may need selenium supplements since they often do not get enough in the diet.

Nature’s Life offers the same food-form yeast-based selenium used in a recent double-blind study.

Our yeast-based selenium is pure Selenomax® from Nutrition 21®—the same selenium used in many positive studies that describe the benefits of supplemental selenium.

In 1996, FDA announced a new 70 mcg. RDI (Recommended Daily Intake) for selenium. Kidney, liver, other meats and some seafood, such as tuna, are the best food sources of selenium. Whole grains, seeds, nuts and garlic18 contain significant amounts of selenium if grown in selenium-rich soil. Fruits, vegetables and drinking water do not contain much selenium.

Selenium at doses up to 700 mcg per day does not produce any signs of toxicity although higher doses (1,000 mcg or more) can cause symptoms of toxicity.
