What Is a Selenium Supplement?

A selenium supplement is a dietary supplement that contains selenium. This trace element is essential for human health because it plays a vital role in the immune system, thyroid function, and reproduction.

You can find selenium in foods such as Brazil nuts, tuna, eggs, and chicken, but the best way to get selenium is through a supplement because it’s not always easy to get enough selenium from diet alone.

Selenium supplements can help ensure that you get the recommended daily amount of this important nutrient with ease, so it’s well worth incorporating one into your routine.

What Are the Benefits of Selenium?

Selenium is a mineral found in many foods, including Brazil nuts, fish, and meat, while also being available as a supplement. Selenium is important for the body because it protects cells from damage, helps the body to produce thyroid hormones, and also aids the body in getting the most out of vitamin E.

Selenium may also help to prevent some types of cancer and heart disease while supporting healthy skin and hair growth, nerve function, and reproductive health.

How Much Selenium To Take Per Day

There is no definitive answer to how much selenium one should take per day, as it depends on individual factors such as age, weight, and overall health.

However, most experts recommend a daily intake of 55 micrograms per day for adults over the age of 19 [1]. Selenium can be found in many foods, such as Brazil nuts, tuna, whole wheat bread, and eggs.

How To Choose A Selenium Supplement

There are many selenium supplements on the market, and it can be difficult to know which one to choose. Here are a few things to consider when choosing a selenium supplement:

  • The best selenium supplements contain selenomethionine, as the body best absorbs this form.
  • Selenium supplements come in many different forms, including capsules, tablets, and liquids. Choose the form that best suits your needs.
  • Be sure to read the label carefully to ensure that the supplement does not contain any fillers or artificial ingredients.
