Selenium acts as an antioxidant with Vitamin E and aids in DNA and protein synthesis. It is these antioxidants that neutralize free radicals and prevent them from damaging tissues and cells. It supports a healthy immune system response (keeps you healthy), prostaglandin production (these are hormone precursors), and healthy reproductive, pancreatic, and thyroid functions. If you remember some of my previous comments about synthetic versus natural vitamins, you'll find that real Vitamin E complex contains selenium. Guess what doesn't? Yes, synthetic Vitamin E. Perhaps that is why when "they" do the studies that conclude Vitamin E does not support heart health, if we look closer we learn they are using synthetic and not real Vitamin E. Seems to make a difference.
Selenium is also important in the blood, cardiovascular, endocrine, enzymatic, immune, integumentary, nervous, and renal systems. Essentially it is used throughout the body.
Where to get it? One of the best sources is Brazil nuts. I have 4-5 every morning in my protein shake. Other sources include barley, broccoli, brown rice, lamb, lean meats, milk, mushrooms, nutritional yeast, organ meats, seafood (cod, crab, halibut, salmon, shrimp, snapper, tuna), tomatoes, turnips, walnuts, wheat germ, and whole grains.
