What It Does and How to Take It
November 12, 2024
Selenium is an essential mineral for our well-being, primarily known for its antioxidant properties, but also crucial for numerous other vital functions.
In this article, we will explore in detail the multiple benefits of selenium, examining the best food sources for obtaining it and the recommended daily intake.
Finally, we will discuss when it may be beneficial to consider supplements to ensure an adequate intake of this valuable micronutrient.
Selenium Properties: An Essential Micronutrient
Selenium plays a crucial role in our bodies. One of its main functions is its involvement in the formation of powerful enzymes that protect cells from oxidation, thus contributing to overall well-being and the prevention of numerous diseases.
In addition to these important benefits, selenium is involved in other vital functions, supporting DNA synthesis, thyroid hormone metabolism, reproduction, and protection against infections.
What Foods Contain Selenium?
Animal-based foods are among the richest sources of this mineral, particularly organ meats, such as liver and kidneys, fish, red meat, and dairy products.
As for plant-based foods, Brazil nuts are particularly rich in selenium, so much so that a small amount is enough to meet daily requirements.
Lastly, some cereals (like potatoes) and mushrooms also contribute to selenium intake, but their content depends heavily on the soil in which they’re grown, which can vary in composition and mineral richness.
Daily Selenium Requirement
The daily dose of selenium varies depending on age and physiological conditions, such as pregnancy and breastfeeding. For young children, the recommended dosage is about 20 micrograms per day up to 3 years old, while between 4 and 8 years, around 30 micrograms per day is recommended.
As children grow, this amount increases: it rises to 40 micrograms per day up to 13 years old, and then reaches 55 micrograms per day from 14 years onward.
During pregnancy and breastfeeding, selenium requirements increase further, rising to 60 and 70 micrograms per day, respectively, to support the proper development of the fetus and the mother’s well-being.
Selenium Deficiency or Excess: Consequences
Ensuring the correct selenium intake is crucial for health, as both deficiency and excess can cause significant problems.
In the case of selenium deficiency, a person may experience altered pigmentation of skin and hair, brittle nails, and even reduced skeletal muscle function. This deficiency can negatively affect red blood cell production and make the body more vulnerable to diseases, especially when additional stressors, such as viral infections, are present. In severe cases, selenium deficiency can increase the risk of couple infertility and worsen the effects of iodine deficiency, with a risk that children may develop cretinism.
On the other hand, an excess of selenium, often due to uncontrolled supplementation, can lead to acute symptoms such as diarrhea, nausea, abdominal pain, vomiting, hair loss, and brittle nails.
Therefore, to avoid risks, it is best to maintain adequate selenium levels through a balanced diet.
Selenium Supplements: What Are the Benefits?
If dietary selenium intake is insufficient, supplements can be an effective solution to ensure an adequate level of this essential mineral.
