Selenium is a part of the enzyme glutathione peroxidase, which metabolizes hydroperoxides formed from polyunsaturated fatty acids. Selenium is also a part of enzymes that deiodinate thyroid hormones. Generally, selenium functions as an antioxidant that works in conjunction with vitamin E.

Silicon
Approximately .05% of our body weight is silica which is absolutely essential for proper body function. It is a primary element in the lungs, spleen, lymph nodes, blood, blood vessels, hair, nails, skin skeletal system, connective tissue, cartilage and tendons. In our youth, our tissues absorb and maintain high levels of silica and simultaneously our bodies remain flexible, resilient and energetic. In addition to this our skin remains soft and supple. With age, levels of silica decline in the body and we begin to exhibit signs of aging such as dry skin, lack of energy and slower healing. Benefits of silicon are relief of joint pain and inflammation reduction, improved skin elasticity and moisturization, stimulation of cell formation, age retardation, immune system enhancement, pain relief from burns, relief of Vertigo, relief of stomach and GI problems and helps Alzheimer's by helping to remove aluminum. The only way to get sufficient amounts of needed silicon is through supplementation.
