Iodine is a very important micronutrient for the basic functions of our body. In particular, it is essential for the proper functioning of the thyroid gland (stimulating the activation of the so-called thyroid hormones). As is known, metabolic decompensations associated with obesity or excessive thinness can arise from thyroid dysfunction. Therefore the good functioning of this gland is also essential to maintain the right weight and an enviable figure. A good functioning of the thyroid is also essential to maintain blood pressure within the right levels (and is therefore fundamental for the well-being of our cardiovascular system) for the expulsion of waste products (toxins) from our organism and to strengthen our immune system also as a consequence of its antioxidant properties which effectively counteracts the harmful action of free radicals in the human body. Iodine is found in foods in trace form and therefore in small quantities. It is present in sea salt, algae, garlic, onion and also in meat. An iodine deficiency can cause thyroid dysfunction with related problems, metabolic dysfunctions and general weakening of our organism. No particular morbid states are found in case of excess of this precious element (very rare in truth). Some studies lead us to believe that an excess of iodine can lead to hyperthyroidism (the effects of which have been agitation, tachycardia, hypertension, etc.).
