**Selenium is popularly thought to be mostly from animal sources but you can easily get it from plant based sources as well. The best sources for selenium are Brazil nuts, seeds, grains, soy beans and mushrooms. (For my Vegan friends) 🙂
Remember it is difficult to get the optimal levels of each antioxidant each day because our fruit and vegetable consumption can not keep up with the oxidative stress demands that our lifestyles create. Besides eating loads and load of the above anti-oxidant rich fruits and veggies, I suggest taking the most highly rated multi-vitamin from USANA, and additional Optimizers such as CoQuinone and Proflavanol.
