Thyroid gland is an important organ of human body, which can secrete the hormone thyroxine that regulates human growth and metabolism. If you secrete too much, it will lead to high metabolism of the human body, which is hyperthyroidism. Hyperthyroidism patients need to control the intake of iodine in their diet. The iodine content of spirulina is only 14-36ug/ 100g, which is the same as that of ordinary vegetables and fruits in China and will not cause hyperthyroidism. At the same time, spirulina is rich in protein, the content of which is as high as 60% or more. It is also rich in eight amino acids and vitamins necessary for human body, which can provide balanced, comprehensive and beneficial nutrition for human body and meet the nutritional needs of hyperthyroidism patients. Moreover, the treatment of hyperthyroidism patients with antithyroid drugs and radiopharmaceuticals is easy to cause granulocytopenia, and in severe cases it can lead to granulocytopenia. Phycocyanin and phycocyanin in spirulina have a good effect on raising white blood cells and reducing adverse drug reactions.
