Selenium

[amazon_link asins=’B00SJKPBNY,B000H85L5Y,B000F4ZVKK,B004R65LWA,B009EA6FZG,B00B5N9IDQ,B000G24ZW6,B00M13NHFY,B01N5FHG46′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’a5b0680f-abf8-11e7-b687-79d16c5dac5a’]

What is selenium?…..click & see
An essential trace element, selenium is nonmetallic, gray in appearance, and similar to sulfur in its chemical composition. It is often available in single or multivitamin supplements.

Why do we need it?
Selenium is needed to activate a number of hormones produced by the thyroid gland. It also activates an antioxidant enzyme called glutathione peroxidase, which may help protect the body from cancer, and has been shown to induce “apoptosis” (programmed cell death) in cancer cells. Selenium also plays a vital role in the functioning of the immune system. Studies have found that selenium supplementation stimulates the activity of white blood cells. It also enhances the effect of vitamin E, one of three vitamins that act as antioxidants.

How much selenium should I take?
According to the National Academy of Sciences, the recommended daily allowance (RDA) of selenium is as follows:

Adult men: 55 micrograms/day
Adult women: 55 micrograms/day
Children aged 7-10: 30 micrograms/day
Infants: between 10-15 micrograms/day
Pregnant/lactating women: between 65-75 micrograms/day


What are some good sources of selenium?

Brazil nuts are the best source of selenium. Yeast, whole grains, garlic and seafood are also good sources. Some vegetables may contain considerable amounts of selenium depending on the content of selenium in the soil.

What can happen if I don’t get enough selenium?
While most people do not consume enough selenium on a daily basis, severe deficiency is rare. Soils in some areas are selenium deficient, and people who eat foods grown primarily on selenium-poor soils can be at greater risk for deficiency. The most notable condition caused by selenium deficiency is Keshan disease, which causes an abnormality of the heart muscle. Some studies have shown that patients with AIDS have abnormally low levels of selenium. Other research has demonstrated an association between heart disease and depleted levels of selenium.

What can happen if I take too much?
Taking large amounts (more than 1,000 micrograms) of selenium per day can cause the loss of fingernails, teeth, and hair; nausea; and fatigue. In conjunction with iodine-deficiency induced goiter, selenium supplementation has been reported to increase the severity of low thyroid function.

Choosing the Right Vitamin

Learn to navigate the supplements aisle with these tips:

Been vitamin shopping lately? If you have, you probably needed to visit the pain-relief aisle afterward for something to deal with the headache all the choices caused. Here’s what clinical nutritionist Shari Lieberman, Ph.D., author of The Real Vitamin and Mineral Book, recommends to make it easier to choose the right ones:

  • Choose natural versions, rather than chemically synthesized versions, when buying fat-soluble vitamins like A, D, E, and beta-carotene.
  • Avoid additives like coal tars, artificial coloring, preservatives, sugars, starch, and other ingredients that you simply don’t need with your vitamin.
  • Don’t worry about chelated minerals. Chelation means the minerals have an added protein to enhance absorption. But they’re often more expensive, and the studies on whether they really are absorbed faster than nonchelated minerals are sparse.
  • Don’t worry about time-release formulations. These supplements may actually take longer to be absorbed and provide you with lower blood levels of the vitamin or mineral.
