Se Aspartate

1 What is Se Aspartate

Se Aspartate is a selenium supplement prescribed to treat or avoid selenium deficiency. Although present only in small amounts, selenium has important functions in the human body. Selenium is an antioxidant (especially with vitamin E), needed for proper thyroid functioning, and may have important role in the functioning of the immune system and disease process of immune system-related conditions such as rheumatoid arthritis.

Selenium is present in several food items such as meat, seafood, and plant-based foods grown in soils rich in selenium. For a reference, a relatively lean meat like ham contains around 33 mcg (micrograms) of selenium.

Deficiency in this mineral is rare in people with healthy diet. Selenium deficiency tends to occur in individuals who are unable to eat due to disease or to those who have severe malabsorption problems.

Dietary selenium requirements vary among age groups, pregnancy, and breastfeeding status. The following describes the recommended dietary intakes (per day) of the mineral:

  • Children younger than 3 years old – 10 mcg (micrograms) to 20 mcg.
  • Children 4 years old to 6 years old – 20 mcg
  • Children 7 years old to 10 years old – 30 mcg
  • Teen and adult men – 40 mcg to 70 mcg
  • Teen and adult women – 45 mcg to 55 mcg
  • Pregnant women – 65 mcg
  • Nursing mothers – 75 mcg
