Selenium Supplements Guide
What Is Selenium?
Selenium is a mineral that can be found in soil, water and in certain foods. The human body doesn’t require much selenium, but if a person has a selenium deficiency, it can be very bad for the health.
Selenium is a naturally-occurring antioxidant that has a number of beneficial effects on the human body. It prevents polyunsaturated fatty acids from oxidizing. It is essential to the formation of prostaglandins, which are integral to keeping the blood moving properly. It works in concert with vitamin E to stimulate growth and to enhance fertility. Selenium also bolsters the immune system. In essence, selenium fights depression, lower cholesterol and keeps the body running as it should.
Selenium comes in two forms, inorganic and organic. Inorganic selenium is found in soil and plants. Organic selenium, also known as selenomethionine or L-selenomethionine, is found in animals. Both forms are fine to take, but selenomethionine has been proven to be easier to digest.
Low levels of selenium are linked to, Crohn’s Disease, and muscular dystrophy. Selenium deficiencies are also suspected to be linked to arthritis, asthma, infertility and certain types of cancer.
Things to Look for in a Good Selenium Supplement
Always look at the label. The safest products are the ones that have the fewest ingredients. There are some that have nothing but selenium, the capsule and the delivery method. Those are often the bet.
Some companies load up selenium supplements with complimentary vitamin like vitamin E to maximize the benefit. It is usually delivered in the form of organic carrots or broccoli. If there are no chemicals in the ingredient list, those are good too if you are willing to spend a little more and are not allergic.
Selenium has a distinctive smell which some people find unpleasant in large quantities. In 2015, it was discovered that there were unscrupulous supplement makers selling products containing fake selenium capsules. They smelled like sawdust. Once you know what selenium smells like, it is an easy way to sort out the fakes from the genuine article.
How to Take Selenium Supplements
Selenium should be taken with food, as that will aid digestion and make it more effective. Never take more than 400 micrograms of selenium in a day. Remember that L-selenomethionine is more potent than inorganic selenium.
If Selenium is taken in large doses, it can be toxic. The symptoms include nausea, cramps, changes in the appearance of fingernails, feelings of fatigue, increased irritability, pain in the arms and legs and a sudden loss of weight. There is some evidence to suggest that taking too much selenium over a long period of time increases the risk of skin cancer. There is also some evidence that too much selenium might also result in prostate cancer or diabetes.
Selenium should not be taken with blood thinners, as there are signs that it could reduce the effects or completely nullify the effects of the medication.
People who are pregnant or lactating should not take selenium until they consult a doctor. We recommend everyone speak with their doctor before taking any supplements featured on this website.
