Why Selenium is Important for Older Adults
As we age, our bodies undergo various changes that can impact nutrient absorption and metabolism. This is where selenium supplements for older adults can play an essential role:
Enhanced Immune Function: Older adults are more susceptible to infections. Selenium supports immune health, making it a valuable supplement.
Reduced Risk of Chronic Diseases: Studies suggest that adequate selenium levels may lower the risk of certain cancers and heart disease.
Cognitive Health: Some research indicates a link between selenium levels and cognitive function, potentially reducing the risk of Alzheimer’s and other dementias.
- Thyroid Health: Thyroid disorders are common in older adults. Selenium supports thyroid function, helping to maintain metabolic balance.
How to Incorporate Selenium Supplements
Choosing the Right Supplement
When selecting selenium supplements for older adults, consider the following:
Form: Selenium comes in various forms, including selenomethionine and sodium selenite. Selenomethionine is often recommended for its higher bioavailability.
- Dosage: The recommended dietary allowance (RDA) for selenium for adults over 50 is 55 micrograms per day. However, consult with a healthcare provider for personalized recommendations.
Dietary Sources of Selenium
In addition to supplements, you can increase your selenium intake through dietary sources:
- Brazil Nuts: One of the richest sources; just a few can meet your daily needs.
- Seafood: Tuna, sardines, and shrimp are excellent options.
- Meats: Chicken, beef, and turkey provide good amounts of selenium.
- Whole Grains: Brown rice and whole wheat bread are beneficial as well.
Practical Tips for Supplementation
Consult Your Doctor: Always consult a healthcare professional before starting any new supplement regimen.
Monitor Your Levels: Regular blood tests can help you and your doctor determine if you need more or less selenium.
- Combine with Other Nutrients: Selenium works synergistically with vitamins E and C, so consider a well-rounded approach to supplementation.

While selenium is essential, excessive intake can lead to toxicity, resulting in symptoms such as:
- Nausea

- Fatigue
- Hair loss
It’s crucial to stick to recommended dosages and consult a healthcare provider if you experience any adverse effects.
