• Sodium Selenite (100 µg per ½ tsp): Provides bioavailable selenium, supporting key selenoproteins involved in antioxidant and thyroid pathways.*
• Glutathione Peroxidase Support: Selenium is required to maintain glutathione in its active, antioxidant state and helps neutralize harmful free radicals.* [2-3]
• Thyroid Health: The thyroid contains more selenium by weight than any other organ; selenium supports healthy thyroid hormone metabolism and function.* [4-5]
• Immune Function: Supports natural killer (NK) cell activity and cytokine regulation, aiding in immune surveillance and response.* [7-9]
• Cellular Detoxification: Plays a key role in liver and kidney detoxification through its role in selenoproteins that process xenobiotics and metabolic waste.* [1]
Ideal for individuals who require precise, titratable selenium dosing and prefer a clean, hypoallergenic formula to support thyroid, immune, or antioxidant system requirements.*
Selenium Solution is heat-sterilized rather than preserved with chemicals and dissolved in pure deionized water. The sodium contribution is nutritionally insignificant, and the formula is free of major allergens. Refrigerate after opening. Always monitor total selenium intake when supplementing.
