What it does: Selenium supports the body's antioxidant defenses by helping neutralize free radicals, aids immune function, and is crucial for activating thyroid hormones and healthy metabolism.
How it is used: Supplements are commonly used to promote antioxidant protection, bolster immune resilience, and maintain normal thyroid hormone activity, especially when dietary intake is insufficient or soil selenium is low.
Natural sources and supplement forms: Major food sources include Brazil nuts, seafood, organ meats, eggs, and whole grains. Supplements often contain selenium as selenomethionine, sodium selenite, or sodium selenate.
Why it appears in supplement formulas: Selenium is included to help address nutrient gaps and to support the body's defenses against oxidative stress, as well as to promote optimal thyroid and immune health.
What to know before use: High intakes of selenium from supplements can be toxic; stay within recommended daily limits and check with a healthcare professional if you take thyroid medication or have health concerns.
Interesting Fact
Selenium: A Nutrient Found in Brazil Nuts and Whole Grains
Selenium is a trace mineral that naturally occurs in foods such as Brazil nuts, seafood, and whole grains. The body uses selenium in small amounts to make special proteins called selenoproteins, which play important roles in various natural processes. Most people get selenium from their diet, but supplement forms provide a consistent source, especially in areas where soil selenium levels are low.
