What is Selenium?
Selenium is one of the minerals our body needs in relatively small amounts to maintain a healthy system.
The body cannot produce its own selenium, so it’s vital for general health that we take in an adequate, regular daily supply. Once ingested, it combines with amino acids (the building blocks of protein) and has a wide variety of effects on the body.
Selenium can be helpful in managing many different health conditions.
Who Needs Selenium?
Due to its antioxidant, antiviral and immune system enhancing properties, potentially everyone can benefit from a regular daily intake of selenium.
Historically, research has shown that selenium is particularly important for people with thyroid conditions and those who have problems with fertility.
However, studies now suggest that regular consumption of selenium has a number of other benefits to health. Here are a few of the most important:
Improves Thyroid Function
According to the American Thyroid Association, approximately 20 million people in the US suffer from thyroid disease.
Selenium has been proven to increase production of active thyroid hormone and reduces the risk of autoimmune thyroid disease. (source)
Antioxidants are chemicals which protect the body from cell damage by absorbing free-radical compounds.
Selenium has been shown to be an effect antioxidant, and research suggests that this is important for a variety of different factors, including risk of heart disease and cancer. (source)
Studies have shown that in people who consume inadequate daily levels of selenium, boosting intake had a beneficial effect on lung cancer. (source) At present, this cannot be generalized to other forms of cancer.
Some research suggests that selenium has anti-inflammatory properties. This is supported by its action as an antioxidant, as these two mechanisms work together in the body. (source)
Health problems caused by viruses are widespread throughout the general population.
Their effect on the human body ranges from being annoying, like the common cold, to life-changing, such as HIV.
Selenium has been shown to have a positive effect on viral infections as a supplementary treatment, but not as a first line therapy. (source)
Selenium has been a recognized treatment for fertility for many years, and the importance of adequate levels of selenium in maintaining healthy sperm cells has been proven. (source)
Protects the Brain and Nervous System
Research suggests that the amino acid chains containing selenium are very important for optimal brain and nervous system function, and are responsible for maintaining an adequate supply of selenium within the brain. (source)
Why Take Selenium As A Supplement?
Although selenium occurs naturally in many of the foods we eat as a part of a normal diet, the selenium content of any given food depends on the selenium content of the soil in which it has been grown. In the case of animal products, the selenium content of the food it has been fed.
In addition, it is very easy to destroy selenium during the cooking process.
Taking a supplement makes sure your body gets a regular dose of selenium in a form that your body can use.
Precautions For Use
People who live in an area where there is an abundance of selenium present naturally is the soil, such as the Dakotas, should not take selenium supplements.
During pregnancy or breast feeding, most manufacturers recommend seeking medical advice before taking selenium.
While studies show that selenium positively affects many types of cancer, there is some evidence to suggest that it can increase the risk of skin cancer. The current recommendation is to avoid higher levels of selenium if you are at risk of skin cancer.
How Much Selenium Do We Need?
Some medical sources state that the maximum daily dose of selenium should not exceed 200 mcg per day.
Other sources suggest that consuming more than the recommended dose of 55mcg per day on an ongoing basis can have toxic effects on the body. Regular overdosing can have serious and permanent consequences for health (source).
The general rule of thumb is to seek medical advice before taking any supplement, especially if you have a health condition or take a prescription medicine.
