Seleniul – an important mineral

Seleniul – an important mineral


Selenium is a trace element that is naturally present in many foods, added to others, and available as a dietary supplement. Selenium, which is nutritionally essential for humans, is a constituent of more than two dozen selenoproteins that play critical roles in reproduction, thyroid hormone metabolism, DNA synthesis, and protection from oxidative damage and infection.


Thyroid disease

Selenium concentration is higher in the thyroid gland than in any other organ in the body, and, like iodine, selenium has important functions in thyroid hormone synthesis and metabolism.

Hashimoto’s disease, also called chronic lymphocytic thyroiditis or autoimmune thyroiditis, is an autoimmune disease. In Hashimoto’s disease, the immune system attacks the thyroid gland, causing inflammation and interfering with its ability to produce thyroid hormones. It is the most common cause of hypothyroidism

Selenium supplementation in patients with Hashimoto helps improving thyroid ultrasound echogenicity, and for pregnant women, it prevents postpartum thyroiditis and permanent hypothyroidism.

Graves’ disease, the most a common cause of hyperthyroidism, can be occasionally associated with eye abnormalities. Known as thyroid eye disease (TED), this may include protrusion of the eyeball, swelling of the soft tissues around the eye and, less often, double vision.

The European of The European Endocrinology Society included selenium in the Treatment Guidelines for mild to moderate Graves ophthalmopathy, because it improves eye manifestation and quality of life and prevents the progression to more severe forms.

Procor T contains an optimal dose of selenium, but also Zinc and Copper, for maintaining thyroid heath.
