About the chemical element selenium 

Selenium is a microelement that naturally exists in many foods, it is added to other food and can be taken in the form of food supplements. Selenium which is vital for human beings is a compound element of 24 selenium proteins that takes place in the reproduction, metabolism of the thyroid hormone, DNA synthesis, and the prevention of oxidative damage.

In other words, selenium is an extremely essential mineral for the human body because of its ability to stimulate the immune system and participate in oxidant prevention, which protects from damage an inflammatory, caused by free radicals. Selenium has that prevention role because it increases the antioxidative abilities and the quality of the bloodstream. That way it improves the strength of the organism to strive against diseases and stress.

In addition, selenium takes place in the structure of almost 25 selenium proteins, responsible for the metabolism of thyroid hormones. For example, glutathione peroxidases protect the thyroid gland from free radicals which are formed in the production process of thyroid hormones. Other selenoproteins (iodothyronine deiodinase, DIO) take part in thyroxine conversion (T4) in its active biological form - triiodothyronine (T3)

Selenium sources 

Natural sources of food which are rich in selenium are nuts, eggs, liver, tuna fish, codfish, sunflower seeds, also poultry, and some types of meat. 

Consume food that is rich in selenium, if possible - it is the best choice, especially when these foods are treated and cooked in a delicate way. Selenium itself can be destroyed during thermal treatment. 

Benefits of selenium action for your body 

These are only several ways selenium improves your body condition: 

  • It acts as an antioxidant and protects from oxidative stress;
  • It prevents cancer;
  • Improves the immune system (in children and adults);
  • Improves the bloodstream and decreases heart diseases possibility;
  • Regulates thyroid gland function;
  • Increases longevity in both genders;
  • Helos to reduce asthma symptoms;
  • Improves fertility.

In the next lines, we will emphasize selenium's role in thyroid gland function and thyroid hormones.

The thyroid gland, insufficiency, and selenium 

More and more researchers claim that there is a connection between the metabolism of the thyroid gland and selenium insufficiency in the organism.  Selenium acts as ad catalysator of active thyroid hormones 

The thyroid gland controls many essential body functions such as appetite, sleep, temperature, weight, energy, and others.

The problem with the normal function of the thyroid gland can cause negative symptoms: irritability, muscle weakness, fatigue, weight gain or loss, sleep problems, and many other reactions. Therefore the appropriate selenium intake ensures the thyroid gland function and the body in many different ways.

Selenium insufficiency is related to thyroid gland problems and the synthesis of the right hormones. It gives the ability to look from the other side at the importance of selenium, especially for women organisms.

Selenium acts as a powerful thyroid gland protector and regulates the reactive oxygen production in it, protecting it from the antibodies that can cause thyroid gland diseases.

Important values about selenium intake 

It is important to know that if you consume the proper quantity of selenium during a healthy diet, a larger dose of selenium may not be useful - large doses of about 400 micrograms may be harmful to you. 

Akti Selenium description and purpose 

Natural form supplementation of the mineral is more effective. In patients with Hashimoto's thyroiditis, natural selenium improves the immunological mechanisms.

In patients with Hashimoto's thyroiditis, autoimmune processes cause tissue destruction of the thyroid gland. Typical for Hashimoto's thyroiditis are antibodies in high concentration (TPO-Ab, МАТ)  which the organism produces against thyroid-specific peroxidase, the enzymes which take part in T3 and T4 formation.

Other antibodies which reflect selenium intake are those that which body produces against thyroglobulin -  the protein which forms active thyroid hormones, and antibodies TGab attack that protein.

Acti Selenium intake improves TAT and MAT decrease. If MAT and TAT levels are too high, it means there is an autoimmune process of gland self-destruction. 

Acti Selenium is a product rich in selenium mineral - very important for the antioxidative ability of the body and for complex treatment of Hashimoto's thyroiditis, and others.
