Causes of Selenium Deficiency:
- Low Selenium in Soil: Crops grown in selenium-poor soil may lack adequate levels of this mineral, making dietary sources insufficient.
- Poor Absorption: Certain chronic illnesses or digestive disorders can impair the body’s ability to absorb selenium effectively.
- Low Selenium in Water Sources: In some regions, the local water may contain very low levels of selenium, contributing to overall deficiency.
Symptoms of Selenium Deficiency:
- Weakened Immune System: A lack of selenium can impair immune function, making the body more susceptible to infections and illness.

- Supplements: In some cases, selenium supplements may be recommended to correct or prevent deficiency—always under medical supervision.
- Avoiding Environmental Toxins: Limit exposure to environmental pollutants and heavy metals that may interfere with selenium absorption.
- Regular Health Monitoring: Keep track of your health and consult with a healthcare provider if you experience symptoms that may indicate a deficiency.
