Selenium activates an antioxidant enzyme called glutathione peroxidase, which may help protect the body from cancer. Yeast-derived forms of selenium have induced “apoptosis” (programmed cell death) in cancer cells in test tubes and in animals.1 2 3 A double-blind trial that included over 1,300 people found those given 200 mcg of yeast-based selenium per day for 4.5 years had a 50% drop in the cancer death rate compared with the placebo group.4 Another study found that men consuming the most dietary selenium (assessed indirectly by measuring toenail selenium levels) developed 65% fewer cases of advanced prostate cancer than did men with the lowest levels of selenium intake.5
Selenium is also essential for healthy immune functioning. Selenium supplementation has reduced the incidence of viral hepatitis in selenium-deficient populations, presumably by enhancing immune function.6 Even in a non-deficient population of elderly people, selenium supplementation has been found to stimulate the activity of white blood cells—primary components of the immune system.7 Selenium is also needed to activate thyroid hormones.
In a double-blind trial, selenium supplementation of infertile men improved the motility of sperm cells and increased the chance of conception.
- Helps to shield the body from harmful chemicals in the environment.
- Works synergistically with vitamin E, greatly amplifying the benefits of both.
- About half of the male body’s supply is located in the reproductive system.
Cholesterol is a waxy fat that is present in all human beings. Two sources contribute to the amount of cholesterol in the human body. First, the liver manufactures about 80 percent of it. Second, people consume it by eating animal products such as meat, eggs and dairy products. Cholesterol is carried through the bloodstream by certain proteins (apolipoproteins). When these proteins wrap around cholesterol and other types of fats (lipids) to transport them through the bloodstream, the resulting “packages” are called lipoproteins.
Research has consistently shown that adequate HDL (“good”) cholesterol levels have a protective effect on people’s cardiovascular health. According to the landmark Framingham Heart Study, the risk of heart attack increases by about 25 percent for every 5 milligrams per deciliter (mg/dL) of HDL below the recommended values.
HDL cholesterol has been shown to reverse some of the harmful effects of LDL (“bad”) cholesterol. Therefore, the more bad cholesterol you have, the more HDL cholesterol you will need.
Vitamin E is a fat-soluble vitamin that exists in eight different forms. Each form has its own biological activity, the measure of potency or functional use in the body. Alpha-tocopherol is the most active form of vitamin E in humans, and is a powerful biological antioxidant. Antioxidants such as vitamin E act to protect your cells against the effects of free radicals, which are potentially damaging by-products of the body’s metabolism. Free radicals can cause cell damage that may contribute to the development of cardiovascular disease and cancer. Studies are underway to determine whether vitamin E might help prevent or delay the development of those chronic diseases.
- Free radical protection.
- Helps prevent liver toxic overload.
- A factor in keeping the blood from excessive stickiness or clotting.
- Needed for muscle health.
- Famous for sustaining reproductive health.
These beneficial fats are in the oil naturally found in fish. The omega-3 fats, EPA and DHA, play different but equally vital roles in human health. Though research with omega-3 supplements is promising, most experts recommend eating more fish rather than taking supplements.
EPA - helps make the platelets in blood less sticky which in turn could help prevent the build-up of plaque otherwise leading to a heart attack or stroke.
DHA - may help stabilize heart rhythm; potentially important for people recovering from heart attacks. May help regulate cell membrane functions involved in transmitting signals among brain cells.
It also has these potential benefits:
- Heart disease control
- Rheumatoid arthritis relief
- Healthy brain function
- Colitis fighter
- Blood triglyceride control
- Cancer fighter
