Selenium Supplements

Selenium is an essential mineral involved in various bodily functions: it contributes to the normal functioning of the immune system, protects cells from oxidative stress, helps maintain healthy hair and nails, and supports the normal metabolism of thyroid hormones.

Selenium occurs naturally in various foods, including fish, meat, eggs, dairy products, grains, and nuts. When dietary intake is insufficient, it is important to take a supplement to meet your needs for this important mineral.

What is selenium and what is it used for?

Selenium is a trace element that the body uses to produce various selenoproteins involved in important physiological processes that support the body's well-being.

Its main actions contribute to:

  • Protection of cells from oxidative stress;
  • Normal function of the immune system;
  • Normal metabolism of thyroid hormones;
  • Support for healthy nails and hair.

Selenium is used by the body mainly through selenoproteins, which are proteins containing selenium that participate in various metabolic functions.

What are the dietary sources of selenium?

Selenium is naturally present in various foods, particularly those rich in protein. The main dietary sources include fish and seafood, meat, eggs and dairy products, bread, cereals, legumes and nuts.

The amount present in plant-based foods may also vary depending on the concentration of selenium in the soil and the characteristics of the raw materials.

When dietary intake is not sufficient to meet the body's requirements, supplementation with selenium-containing products may be considered, always taking into account the total intake from the diet.

How should the amount of selenium per serving be assessed?

It is important to check the amount of selenium actually provided by the daily serving indicated on the label and to also consider the amount obtained from the diet so as not to exceed the recommended daily intake.

For supplementation, it is advisable to maintain a consistent and regular dosage. In the case of medication or specific health conditions, it is essential to assess the most appropriate amount and any possible interactions with a doctor or trusted healthcare professional.

Selenium tablets: what are their characteristics?

Selenium tablets are a practical format that allows you to take a predefined amount of the mineral. The method and frequency of intake depend on the instructions provided on the label.

Frequently asked questions about selenium supplements

What is selenium used for?

Selenium is an essential mineral for protecting cells from oxidative stress, supporting the metabolism of thyroid hormones and maintaining the normal function of the immune system. It is also involved in other biological processes, including DNA synthesis and reproduction.

Selenium contributes to the protection of cells from oxidative stress through the role of certain selenoproteins in enzymatic systems that counter oxidative processes. It is involved in the normal metabolism of thyroid hormones and in the reactions that allow thyroid hormones to be converted into their active forms. The thyroid is one of the organs with the highest concentration of selenium in the body.

When should a selenium supplement be taken?

Selenium supplementation may be considered when dietary intake is not sufficient to meet the body's requirements.

There is no specific time of day for taking a supplement that is suitable for everyone. It is advisable to follow the instructions provided on the product label and consider the total amount of selenium consumed throughout the day, including through food.

How can you tell if you are getting too little selenium?

It is not always easy to determine whether you are getting too little selenium because insufficient intake does not necessarily cause specific and easily recognisable signs.

It is not appropriate to establish a deficiency based simply on a single symptom: manifestations such as tiredness, changes in hair or nails and other disorders may have many different causes and, on their own, are not sufficient to attribute a problem to selenium.

When there is a concrete reason to suspect insufficient intake, an assessment may take into account dietary habits, individual circumstances and, when necessary, specific laboratory tests.

How should you choose a selenium supplement?

It is useful to assess the amount of selenium per serving, the form used, any additional ingredients and the recommended method of intake. It is also important to consider the selenium intake from the diet and avoid combining several products without checking their total selenium content.

Does selenium contribute to normal thyroid function?

Yes, selenium contributes to the normal metabolism of thyroid hormones. This mineral is involved in the production and metabolism of thyroid hormones through specific selenoproteins.
