Unlike other supplements for thyroid eye disease, Thyro Eye Caps are a dietary supplement which combine selenium and vitamin D. Selenium is a naturally occurring trace element, and vitamin D is a fat soluble steroid. This combination has been developed by UK-based ophthalmic (eye) surgeons. By fighting free radicals, Selenium is thought to play an important role in all functions of the eye. Free radicals can cause cataract, and therefore healthy amounts of Selenium intake can protect the lens of the eye and prevent or delay cataract formation. The thyroid gland has the highest concentration of Selenium of any organ in the human body. It plays a very important role in the healthy functioning of the thyroid gland, which in turn regulates many body activities such as digestion and food absorption, body temperature control and even mood. Therefore, a healthy selenium intake is vital for maintaining thyroid and overall bodily health, and is particularly important for those suffering from an underactive thyroid, overactive thyroid, or Graves' disease. Low Selenium levels have been associated with conditions like hypo and hyperthyroidism (Hashimoto’s thyroiditis and Graves disease). Vitamin D has been linked to eye health in many ways and is thought to support the eye in several different conditions. Specifically, it’s role in inflammation may help support the eyes where thyroid problems also exist. Research has suggested that vitamin D may help support the thyroid gland when in an under-active state (hypothyroidism). Low levels of vitamin D have also been associated with an overactive thyroid gland (hyperthyroidism). Recommended usage: 1 daily tablet swallowed whole with water.
