About This Product
Pure Encapsulations Selenium provides 200 mcg of selenomethionine per capsule, the most bioavailable and well-researched form of selenium. Pure Encapsulations is known for their hypoallergenic formulations — this product is free from gluten, dairy, soy, GMOs, artificial colors, flavors, and unnecessary additives. Each batch is third-party tested for purity and potency. The capsules are small and easy to swallow, and the 200 mcg dose aligns with the amount used in major clinical trials studying selenium's effects on thyroid autoimmunity, including the landmark studies on TPO antibody reduction.
Why This Is Great for Thyroid Patients
Selenium is arguably the single most important mineral for thyroid health beyond iodine. It is required for the selenoprotein enzymes that convert T4 into the active T3 hormone, and it plays a critical role in protecting the thyroid gland from oxidative damage during hormone production. Clinical studies have shown that 200 mcg of selenium daily can significantly reduce TPO antibodies in Hashimoto's patients. Pure Encapsulations delivers pharmaceutical-grade quality with zero fillers, making it ideal for sensitive thyroid patients who react to additives in cheaper brands.
