1) Selenium Quick Facts
Selenium is a formula that claims to provide immune support as well as antioxidant protection. The supplement provides customers with 200 mcg of Selenium, which accounts for about a quarter of the daily maximum allowance.
Selenium can be toxic if taken excessively; however, taken in recommended doses, this supplement can prove very helpful. Clinical studies have proven that this mineral prevents cell deterioration due its antioxidant effect. Free radicals can severely damage or weaken cell membranes, speeding up the aging process and inhibiting the proper functioning of some organs. Antioxidants such as Selenium, particularly when taken in combination with Vitamin E, can greatly reduce this effect, promoting a better functioning of the human body.
2) What Are Selenium Ingredients?
Selenium contains: Calcium Carbonate, Dried Yeast, Cellulose Gel, Maltodextrin, Stearic Acid, Silicon Dioxide, Hydroxypropyl Methylcellulose, Magnesium Stearate, Sodium Selenite, and Polyethylene Glycol.
3) Does Selenium Work?
Selenium delivers 200 mcg (0.2mg the daily recommended daily allowance) of Selenium per tablet. This formula is claimed to offer potent antioxidant protection and support a healthy immune system.
As an antioxidant, this trace mineral prevents the propagation of free radicals in tissues. Oxidative stress damages the membranes of the cells and kills some of them. Although these free radicals play a few essential roles in our bodies, large quantities of them can speed up the aging process and affect the functioning of sensitive organs such as the eyes. Besides its antioxidant function, researchers have found that selenium has hepatoprotective effects along with Vitamin E. Some studies suggest it also supports the functioning of the cardiovascular system, ameliorating conditions such as cardiomyopathies, ischemic and other anemic syndromes. Selenium may help the immune system as it stimulates the production of white blood cells.
The manufacturer recommends taking one tablet of Selenium daily. Please note that getting too much of this mineral is as dangerous as its deficiency. Excess of this mineral can lead to hair loss, nausea, irritability, asthenia, and other neurologic problems.

8) Our Verdict on Selenium
Products containing Selenium have been frowned upon during the last decade, due to the potentially toxic effect this mineral can have. Most health specialists recommend that the daily required dosage of Selenium should be acquired through our food, to reduce the chance of selenium poisoning. For some people, this is a difficult task, as they may not have the necessary time to support a healthy, balanced diet.
Selenium has been tried by numerous customers, none of them reporting any negative side effects. It would appear that, as long as the recommended dosage is respected, this supplement can support immune function and provide cellular protection.
