Selenium is one of the trace minerals that, although the body only needs it in small amounts, plays a crucial role in maintaining health. It acts as a powerful antioxidant, helping protect cells from damage, and is essential for a strong immune system and proper thyroid function. However, like any nutrient, balance is key! A deficiency can cause problems, and excess intake can be harmful. In this medical guide, we will explore its types, benefits, and the groups that may be more prone to deficiency.
Types of Selenium
Organic Selenium (Easier to absorb and more beneficial to the body)
Selenomethionine
The body absorbs it quickly and efficiently.
Found in nuts, whole grains, and meats.
It’s the most commonly used form in dietary supplements.
Selenocysteine
Found in protein-rich foods like eggs and meats.
Plays a key role in enzymes that fight oxidation.
Inorganic Selenium (Lower absorption, but beneficial in appropriate doses)
Sodium Selenate
Used in some medications and research to treat nerve diseases.
The body converts it into an active form of selenium.
Sodium Selenite
Taken as a dietary supplement, but its absorption is lower than selenomethionine.
Can be used to treat selenium deficiency in the body.
Groups at Risk of Selenium Deficiency
People with digestive issues
Kidney patients undergoing dialysis
Dialysis reduces selenium levels in the blood.
People living in areas with selenium-poor soil
Some regions, such as parts of China and Europe, have selenium-deficient soil, so the food grown there is not rich in it.
Immune-compromised patients, especially those with HIV/AIDS
Selenium helps strengthen the immune system, and people with HIV/AIDS are often deficient in it.
People with a diet poor in selenium

Components of Selenium Supplements
Selenium supplements vary in type and composition. The most common forms include:

The form the body absorbs easily and benefits from.
Found in both animal and plant-based proteins.
Stored in the body for a longer period.
Selenocysteine
Found in foods like garlic and onions.
Part of enzymes that protect cells from damage.
Inorganic Selenium (weaker absorption)
Sodium Selenite
Found in some dietary supplements.
The body absorbs it slowly compared to organic selenium.
Sodium Selenate
Rarely used, but important in certain medical treatments.
