Selenium is an essential trace mineral that plays a critical role in immune function, antioxidant defense, thyroid hormone metabolism, and cellular protection. It is required for the production of several important antioxidant enzymes that help protect cells from oxidative stress and inflammation.

Selenium is commonly used in integrative medicine to support immune health, thyroid function, detoxification pathways, and overall cellular resilience.

Potential Benefits

• Supports healthy immune system function
• Provides antioxidant protection against oxidative stress
• Supports normal thyroid hormone metabolism
• Helps maintain healthy inflammatory balance
• Supports brain and nervous system health
• Promotes cellular protection and repair
• Supports detoxification pathways
• Helps maintain healthy mitochondrial function
• Supports overall metabolic health

How It Works

• Supports production of glutathione peroxidase and other antioxidant enzymes
• Helps neutralize free radicals and oxidative damage
• Supports conversion of thyroid hormone T4 to active T3
• Protects cells from inflammation-related injury
• Supports healthy immune cell function

Why It Is Helpful in AN Protocol

For autistic children and adults, as well as individuals with PANS/PANDAS and neuroimmune disorders:

• Supports immune system regulation
• Helps reduce oxidative stress associated with chronic inflammation
• Supports healthy thyroid function, which may influence mood, cognition, and energy levels
• Promotes neurological and mitochondrial health
• May help support recovery from chronic infections and inflammatory conditions

Key Mechanism

Selenium supports health primarily through:

• Antioxidant enzyme activity
• Immune regulation
• Thyroid hormone metabolism
• Cellular protection
• Reduction of oxidative stress

Suggested Use

Typical dose: 200 mcg daily or as directed by a healthcare professional.

Important

• Do not exceed recommended doses without medical supervision.
• Long-term excessive selenium intake may cause toxicity.
• Selenium works synergistically with zinc, vitamin E, and glutathione-dependent antioxidant systems.
