Selenium Solution from Allergy Research Group delivers selenium in liquid form, offering a flexible dosing option for those who prefer to avoid capsules or tablets. Selenium is an essential trace mineral that supports antioxidant defense, thyroid hormone metabolism, and immune function.
Why It's Worth Considering: Allergy Research Group formulates this as a concentrated liquid, making it well-suited for practitioners who need precise, adjustable dosing for sensitive patients or those with swallowing difficulties.
As a dietary supplement, 1/2 teaspoon three times daily, or as directed by a healthcare practitioner. Do not exceed daily dose.
For maintenance: 100-200mcg daily (selenomethionine form preferred). For thyroid support: 200mcg. The RDA is 55mcg but most functional medicine practitioners recommend 100-200mcg. Do NOT exceed 400mcg/day, selenium has a narrow therapeutic window and excess causes selenosis (hair loss, nail brittleness, GI issues).
Yes, selenium is critical for thyroid function. It's required for the enzyme that converts inactive T4 to active T3, AND it protects thyroid cells from oxidative damage. In Hashimoto's, 200mcg selenium daily reduces TPO antibodies by 20-40% in clinical trials. It's one of the most evidence-based supplements for thyroid health.
One Brazil nut contains 70-90mcg selenium, so 2 nuts/day provides a therapeutic dose. However, selenium content varies dramatically by soil (some nuts have 10mcg, others have 300mcg). If you rely on Brazil nuts, be cautious about overconsumption, 4-5 large nuts could exceed 400mcg. A supplement provides a consistent, known dose.
