Thyroid problem is mainly due to malnutrition and proper intake of vitamins can mitigate the problem to a great extent. There is a correlation between levels of thyroid hormones and levels of specific micronutrients such as selenium, zinc, retinol, and alpha-tocopherol. Several studies are being conducted to assess the impact of vitamin intake on thyroid related problems.
Problem of Thyroid
it is an important gland and releases many hormones which are necessary for the proper functioning of the body including the maintenance of cellular machinery in the human body. A condition or disease known as Hyperthyroidism can start affecting a person when the thyroid gland produces excess thyroid hormone. In this condition, the body’s metabolic rate runs too fast and metabolism is rapid compared to the normal rate. The secretion of too little of the thyroid hormone will lead to the converse disorder known as Hypothyroidism.
Research on Vitamins and Thyroid
Patients suffering from hypothyroidism often have an increase in levels of homocysteine. Intake of B vitamins through diet, supplementation and fortified foods will increase levels of homocysteine, but there is no evidence that such supplements will modify thyroid function in individuals with thyroid disease.
Although selenium is clearly important for optimal synthesis of thyroid hormones, and the thyroid gland normally stores both iodine and selenium, there is little scientific evidence from well-designed studies to suggest that selenium supplementation has sustained beneficial effects on thyroid function.
Several studies, often non-randomized, have shown modest changes in levels of antibodies, but no clear improvement in thyroid hormone levels as shown in. Patients with thyroid disease should take supplements containing molecules with anti-oxidant properties, such as vitamin C, vitamin E, and coenzyme Q10.
While the risks and benefits of soy supplementation for various medical conditions continue to be debated, patients taking large amounts of soy may experience reduced absorption of thyroid hormone and an increased requirement for L-thyroxine, particularly in the setting of iodine deficiency.
Patients ingesting increased amounts of fiber in their diets may also require unusually high does of L-thyroxine.
Research also indicates that L-carnitine can function as an antagonist of thyroid hormone, likely by blocking the entry of thyroid hormone into cells. Indeed, these properties of L-carnitine may be beneficial in hyperthyroid subjects. As hyperthyroidism may be associated with modest carnitine deficiency, the effects of carnitine supplementation were examined in a small randomized trial of women on L-thyroxine supplementation.
Although not directly involved in synthesis or secretion of thyroid hormones, vitamin D deficiency can produce increases in the levels of parathyroid hormone and increase the risk of osteoporosis.
How Important are the Vitamins ?
Vitamin C and B-complex vitamins are very important. They play an important role in bringing about an improvement in the general functioning of the individual’s immune system along with the functioning of the thyroid gland itself. Amino acid tyrosine for proper thyroid functioning. Zinc and copper also form the overall functioning of the thyroid gland.
It is obvious vitamins are essential for the thyroid to function well. Research is still on the effects of various supplements on the thyroid system.

[…] Diminished thyroid activity, or hypothyroidism, decreases metabolic rate, makes it impossible to assimilate food properly, depresses the activity of other glands in the body, and ultimately adversely affects every cell and tissue in the body. Hypothyroidism occurs when your thyroid gland, at the front of your neck, doesn’t produce enough thyroid hormone or when your body fails to use thyroid hormone efficiently. […]
