Selenium supports a host of different metabolic processes and serves as an antioxidant that protects our cells. According to recent studies, selenium also has anti-ageing properties that protect us against cardiovascular disease, cancer, dementia, and other age-related diseases. According to a review article published in Medical News Today, selenium also helps against impaired immunity and counteracts chronic inflammation, which is typically seen in connection with ageing processes. A Swedish study of healthy seniors has even showed that supplementation with selenium and Q10 has a positive effect on heart function, quality of life, and life expectancy.

An estimated 500,000 Danes suffer from some kind of thyroid disorder, the most common of which is Hashimoto’s disease, which slows down your metabolism. The formation and activation of thyroid hormones depend on iodine and selenium, and it is essential that the two nutrients are properly balanced. Having too little or too much iodine increases your risk of Hashimoto’s disease, and the same is the case with selenium, a nutrient that many people lack.
Some of the problems that are seen in people with slow metabolism are extreme fatigue, weight gain, constipation, cold sensitivity, swollen neck, and dry skin. The symptoms can vary, however, and many people still have not been given the proper diagnosis.
Medical therapy with thyroid hormones will not necessarily solve the problem. In fact, as many as 20 percent of patients actually feel worse, although their blood tests appear to be normal. It is therefore important to focus more in the role of iodine and selenium in the metabolism.
