In July of 1995, the United States Department of Agriculture officially published research information, which acknowledges Selenium as "an essential trace element known for its antioxidant prowess."

In addition to this, the mineral has been recognized for its ability to lift the spirits, and prevent mood swings of those who take it as a nutritional supplement. In a 15-week clinical study, 30 men reported significant changes in their moods, as judged by a standard questionnaire. The study indicated that after taking selenium for an extended period of time, the men who took the highest dosages of selenium felt more elated than depressed, more agreeable than hostile, more clearheaded than confused, more confident than unsure, more composed than anxious, and more energetic than tired. These powerful results indicate that Selenium has many other benefits in addition to its most obvious purpose as an antioxidant.

In the years since this study took place, more and more evidence has surfaced supporting Selenium as playing an essential role in the maintenance of a healthy immune system, and good general wellness. Selenium is one of those supplements that not only improves your health, but also has the added bonus of making you feel good at the same time. In short, you can actually feel it working.
