What is the recommended dosage for Selenium?

General: 55 mcg/day; Immune Support: 100-200 mcg/day

What are the side effects of Selenium?

Potential side effects include: Selenosis at chronic high doses (hair loss, nail brittleness, garlic breath odor), Nausea and diarrhea, Fatigue and irritability, Nerve damage (peripheral neuropathy) at very high chronic doses.

What is selenium and how does it support the immune system?

Selenium is an essential trace mineral incorporated into selenoproteins that regulate immune cell function, antioxidant defense, and thyroid hormone metabolism. Selenium deficiency is associated with impaired immune responses and increased susceptibility to viral infections.

What dosage of selenium has been studied for immune health?

Clinical studies have used selenium at doses of 50–200 mcg per day, with 100–200 mcg being the most common range for immune outcomes. The Tolerable Upper Intake Level is 400 mcg per day, and exceeding this can cause toxicity.

What are the potential side effects of selenium supplementation?

Chronic intake above 400 mcg per day can cause selenosis, characterized by hair loss, nail brittleness, garlic breath, fatigue, and gastrointestinal symptoms. Selenium has a narrow therapeutic window, and supplementation should be based on dietary intake assessment.

About

Selenium is an essential component of selenoproteins (glutathione peroxidases, thioredoxin reductases) that regulate oxidative stress and redox signaling in immune cells. It supports optimal innate and adaptive immune responses and thyroid function. Adequate selenium status is associated with enhanced NK cell activity and improved vaccine response.
