3 microU/mL) if they consumed iodine supplements in doses ≥200 mcg/day compared with those who consumed doses <100 mcg/day [68]. gas. The US recommended daily intake for iodine is 150 mcg/day for adults, and the FDA’s limit is set at 1 mg/day. Prevention and control of iodine deficiency in pregnant and lactating women and in children less than 2-years-old: conclusions and recommendations of the Technical Consultation. 1996;66(4):350-362. This section focuses on four areas of biomedical research examining iodine’s role in health and disease: fetal and infant development, cognitive function during childhood, fibrocystic breast disease, and radiation-induced thyroid cancer. According to some iodine experts, the requirement of the whole human body for iodine … * Formula and food should be the only sources of iodine for infants. Iodine probably attacks surface proteins of enveloped viruses, and it may also destabilise membrane fatty acids by reacting with unsaturated carbon bonds. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet. The DV for iodine is 150 mcg for adults and children aged 4 years and older [12]. Nauman J, Wolff J. Iodide prophylaxis in Poland after the Chernobyl reactor accident: benefits and risks. For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The addition of iodine to table salt has largely eliminated this problem in wealthier nations, but iodine deficiency remains a serious public health problem in the developing world today. In areas where iodide prophylaxis was not used, such as Belarus and Ukraine, where many children were mildly iodine-deficient, the incidence of thyroid cancer sharply increased among children and adolescents [77]. Salt iodization programs, which many countries have implemented, have dramatically reduced the prevalence of iodine deficiency worldwide [2,3]. Copper, Manganese, Selenium, and Iodine, U.S. Food and Drug Administration, Code of Federal Regulations, CFR 21, Sections 184.1634 and 184.1265, National Health and Nutrition Examination Survey Data, Global scorecard of iodine nutrition in 2019, Potassium iodide as a thyroid blocking agent in radiation emergencies, Guidelines for Iodine Prophylaxis following Nuclear Accidents, Bread, whole-wheat, made with iodate dough conditioner, 1 slice, Bread, white, enriched, made with iodate dough conditioner, 1 slice, Iodized table salt, 1.5 g (approx. *DV = Daily Value. [90] The toxicity derives from its oxidizing properties, through which it denaturates proteins (including enzymes). According to the WHO, a median urinary iodine concentration of 150–249 mcg/L indicates adequate iodine nutrition during pregnancy, while values less than 150 mcg/L are considered insufficient [3,7]. The major form of thyroid hormone in the blood is thyroxine (T4), which has a longer half-life than T3. Your thyroid gland, which is … 1990 Nov;90(11):1571-1581. Anti-thyroid medications, such as methimazole (Tapazole®), are used to treat hyperthyroidism.

Foods in nutrient-dense forms contain essential vitamins and minerals and also dietary fiber and other naturally occurring substances that may have positive health effects. Includes a variety of protein foods, including seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products. Center for Drug Evaluation and Research, Food and Drug Administration. Studies have also shown that excessive iodine intakes cause thyroiditis and thyroid papillary cancer [2,80]. The FDA has approved the use of potassium iodide and cuprous iodide for salt iodization [19], whereas the WHO recommends the use of potassium iodate due to its greater stability, particularly in warm, damp, or tropical climates [3]. The median iodine content was 150 mcg per daily serving, with a range of 25 to 290 mcg; 25 of the 34 provided iodine as potassium iodide. [, Murray CW, Egan SK, Kim H, Beru N, Bolger PM.

Prevention and control of iodine deficiency in pregnant and lactating women and in children less than 2-years-old: conclusions and recommendations of the Technical Consultation. 1996;66(4):350-362. This section focuses on four areas of biomedical research examining iodine’s role in health and disease: fetal and infant development, cognitive function during childhood, fibrocystic breast disease, and radiation-induced thyroid cancer. According to some iodine experts, the requirement of the whole human body for iodine … * Formula and food should be the only sources of iodine for infants. Iodine probably attacks surface proteins of enveloped viruses, and it may also destabilise membrane fatty acids by reacting with unsaturated carbon bonds. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet. The DV for iodine is 150 mcg for adults and children aged 4 years and older [12]. Nauman J, Wolff J. Iodide prophylaxis in Poland after the Chernobyl reactor accident: benefits and risks. For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The addition of iodine to table salt has largely eliminated this problem in wealthier nations, but iodine deficiency remains a serious public health problem in the developing world today. In areas where iodide prophylaxis was not used, such as Belarus and Ukraine, where many children were mildly iodine-deficient, the incidence of thyroid cancer sharply increased among children and adolescents [77]. Salt iodization programs, which many countries have implemented, have dramatically reduced the prevalence of iodine deficiency worldwide [2,3].

[90] The toxicity derives from its oxidizing properties, through which it denaturates proteins (including enzymes). According to the WHO, a median urinary iodine concentration of 150–249 mcg/L indicates adequate iodine nutrition during pregnancy, while values less than 150 mcg/L are considered insufficient [3,7]. The major form of thyroid hormone in the blood is thyroxine (T4), which has a longer half-life than T3. Your thyroid gland, which is … 1990 Nov;90(11):1571-1581.

The US recommended daily intake for iodine is 150 mcg/day for adults, and the FDA’s limit is set at 1 mg/day. Prevention and control of iodine deficiency in pregnant and lactating women and in children less than 2-years-old: conclusions and recommendations of the Technical Consultation. 1996;66(4):350-362. This section focuses on four areas of biomedical research examining iodine’s role in health and disease: fetal and infant development, cognitive function during childhood, fibrocystic breast disease, and radiation-induced thyroid cancer. According to some iodine experts, the requirement of the whole human body for iodine … * Formula and food should be the only sources of iodine for infants. Iodine probably attacks surface proteins of enveloped viruses, and it may also destabilise membrane fatty acids by reacting with unsaturated carbon bonds. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet. The DV for iodine is 150 mcg for adults and children aged 4 years and older [12]. Nauman J, Wolff J. Iodide prophylaxis in Poland after the Chernobyl reactor accident: benefits and risks. For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The addition of iodine to table salt has largely eliminated this problem in wealthier nations, but iodine deficiency remains a serious public health problem in the developing world today. In areas where iodide prophylaxis was not used, such as Belarus and Ukraine, where many children were mildly iodine-deficient, the incidence of thyroid cancer sharply increased among children and adolescents [77]. Salt iodization programs, which many countries have implemented, have dramatically reduced the prevalence of iodine deficiency worldwide [2,3]. Copper, Manganese, Selenium, and Iodine, U.S. Food and Drug Administration, Code of Federal Regulations, CFR 21, Sections 184.1634 and 184.1265, National Health and Nutrition Examination Survey Data, Global scorecard of iodine nutrition in 2019, Potassium iodide as a thyroid blocking agent in radiation emergencies, Guidelines for Iodine Prophylaxis following Nuclear Accidents, Bread, whole-wheat, made with iodate dough conditioner, 1 slice, Bread, white, enriched, made with iodate dough conditioner, 1 slice, Iodized table salt, 1.5 g (approx. *DV = Daily Value. [90] The toxicity derives from its oxidizing properties, through which it denaturates proteins (including enzymes). According to the WHO, a median urinary iodine concentration of 150–249 mcg/L indicates adequate iodine nutrition during pregnancy, while values less than 150 mcg/L are considered insufficient [3,7]. The major form of thyroid hormone in the blood is thyroxine (T4), which has a longer half-life than T3. Your thyroid gland, which is … 1990 Nov;90(11):1571-1581. Anti-thyroid medications, such as methimazole (Tapazole®), are used to treat hyperthyroidism. Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA. ... Foods in nutrient-dense forms contain essential vitamins and minerals and also dietary fiber and other naturally occurring substances that may have positive health effects. Includes a variety of protein foods, including seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products. Center for Drug Evaluation and Research, Food and Drug Administration. Studies have also shown that excessive iodine intakes cause thyroiditis and thyroid papillary cancer [2,80]. The FDA has approved the use of potassium iodide and cuprous iodide for salt iodization [19], whereas the WHO recommends the use of potassium iodate due to its greater stability, particularly in warm, damp, or tropical climates [3]. The median iodine content was 150 mcg per daily serving, with a range of 25 to 290 mcg; 25 of the 34 provided iodine as potassium iodide. [, Murray CW, Egan SK, Kim H, Beru N, Bolger PM.

In total, they can contain at least 0.02% and at most 1% iodine by mass. During pregnancy and early infancy, iodine deficiency can cause irreversible effects. Literally, the correct formula for potassium and iodine at standard temperature and pressure would be " K and I2". Cases of acute iodine poisoning are rare and are usually caused by doses of many grams. USDA, … In these technologies, which support the world's demand for acetic acid, hydroiodic acid converts the methanol feedstock into methyl iodide, which undergoes carbonylation. This article is about the chemical element. Can J Surg. The amount of iodine absorbed (in milligrams) by 1 g of carbon using test conditions listed herein is called the iodine number. It is often used as a sensitive spot test for ammonia. [, Bath SC, Steer CD, Golding J, Emmett P, Rayman MP. [, Zimmermann MB. [.

Intelligence quotient and iodine intake: a cross-sectional study in children. Pennington JAT, Schoen SA, Salmon GD, Young B, Johnson RD, Marts RW. For a population of school-aged children or non-pregnant adults to be iodine sufficient, median urinary iodine concentrations should be greater than 100 mcg/L and no more than 20% of the population should have values lower than 50 mcg/L [3]. Radiation-induced thyroid cancer 2009 Jun;30(4):376-408. Consumption of foods that contain goitrogens, substances that interfere with the uptake of iodine in the thyroid, can exacerbate iodine deficiency [2]. Atom number 53. [79] Its specific mode of action is unknown. Thyroid 2017;27:315-89. The prevalence of iodine deficiency in women of reproductive age in the United States of America. In dietary supplements, iodine is often present as potassium iodide or sodium iodide [20]. 2009 Jun;89(6):2052S-2069S. Urinary iodine reflects dietary iodine intake directly because people excrete more than 90% of dietary iodine in the urine [4]. Suboptimal iodine status during pregnancy has also been observed in Australia [38]. This initial release includes about 430 foods. Altern Med Rev. [77], In the alternative, iodine may be produced from iodophors, which contain iodine complexed with a solubilizing agent (the iodide ion may be thought of loosely as the iodophor in triiodide water solutions). Although the results of these studies are promising, more research is needed to clarify iodine’s role in fibrocystic breast disease. [, Melse-Boonstra A, Jaiswal N. Iodine deficiency in pregnancy, infancy and childhood and its consequences for brain development. Food Labeling: Revision of the Nutrition and Supplement Facts Labels. Tolerable Upper Intake Level (UL): Maximum daily intake unlikely to cause adverse health effects. The iodine is prepared as a Lugol’s solution of 2:1, potassium iodide (KI) : iodine (I 2). After filtering and purification the iodine is packed. Taken as a whole, these findings indicate that increased public awareness of iodine’s importance during pregnancy and lactation is warranted and that further research into the effects of iodine supplementation during pregnancy is needed. [110], Elemental iodine is also a skin irritant. Mild to moderate maternal iodine deficiency has also been associated with an increased risk of attention deficit hyperactivity disorder in children [43]. Although iodine is not particularly ab… 2010 Aug;140(8):1489-1494. [92] This upper limit was assessed by analyzing the effect of supplementation on thyroid-stimulating hormone. TDS data do not include iodine that people obtain from the discretionary use of iodized salt [25,26]. Fifteen to 20 mg of iodine is concentrated in thyroid tissue and hormones, but 70% of all iodine in the body is found in other tissues, including mammary glands, eyes, gastric mucosa, fetal thymus, cerebro-spinal fluid and choroid plexus, arterial walls, the cervix, and salivary glands. Ground State Level: 2Po3/2: Standard State… Reduced educational outcomes persist into adolescence following mild iodine deficiency in utero, despite adequacy in childhood: 15-year follow-up of the gestational iodine cohort investigating auditory processing speed and working memory. After 5 months of treatment, women receiving doses of 3,000 or 6,000 mcg iodine had a significant decrease in breast pain, tenderness, and nodularity compared with those receiving placebo or 1,500 mcg iodine. [, Zimmermann MB. Hence taking infinite-dilution behavior to be the standard state allows corrections for non-ideality to be made consistently for all the different solutes. These are further processed by decarboxylation and deiodination to produce iodothyronamine (T1a) and thyronamine (T0a'). 2004 Aug;89(8):3851-3857. Standard State of Diatomic Molecules. Iodine is also present in human breast milk [2,5] and infant formulas [8]. ; Harrison, R.W. [99] In Japan, consumption was considered much higher, ranging between 5,280 μg/day to 13,800 μg/day from dietary seaweed or kombu kelp,[90] often in the form of Kombu Umami extracts for soup stock and potato chips. Air is blown into the solution to evaporate the iodine, which is passed into an absorbing tower, where sulfur dioxide reduces the iodine. Iodide is quickly and almost completely absorbed in the stomach and duodenum. [, Poulsen E. Case study: erythrosine. Some research suggests that iodine supplementation might be helpful for fibrocystic breast disease, although a specific mechanism of action has not been established [75] and data are limited. For women living in countries with weak, sporadic, or uneven iodized salt distribution, the WHO recommends iodine supplementation for all women of childbearing age to achieve a total iodine intake of 150 mcg/day. J Expo Sci Environ Epidemiol 2018;28:21-30. The Occupational Safety and Health Administration (OSHA) has set the legal limit (Permissible exposure limit) for iodine exposure in the workplace at 0.1 ppm (1 mg/m3) during an 8-hour workday. Methods to assess iron and iodine status. Similarly, the American Academy of Pediatrics recommends that women who are pregnant, planning to become pregnant, or lactating take a daily supplement providing at least 150 mcg iodine and use iodized salt [66]. Manufacturers list dough conditioners as an ingredient on product labels but are not required to include iodine on the Nutrition Facts label [12], even though these conditioners provide a substantial amount of iodine.

Mountainous areas (e.g., Himalayas, Alps, and Andes regions) and river valleys prone to flooding (especially in South and Southeast Asia) are among the most iodine-deficient regions in the world [5]. 1993 Oct;36(5):453-460. Solutions with high elemental iodine concentration, such as tincture of iodine and Lugol's solution, are capable of causing tissue damage if used in prolonged cleaning or antisepsis; similarly, liquid Povidone-iodine (Betadine) trapped against the skin resulted in chemical burns in some reported cases. Direct contact with skin can cause damage, and solid iodine crystals should be handled with care. The World Health Organization (WHO), United Nations Children’s Fund (UNICEF), and the International Council for the Control of Iodine Deficiency Disorders (ICCIDD) recommend a slightly higher iodine intake for pregnant women of 250 mcg per day [3,7]. [4][91] The Tolerable Upper Intake Level (UL) for adults is 1,100 μg/day. Am J Clin Nutr. Iodine deficiency, pollutant chemicals, and the thyroid: New information on an old problem. This is a fact sheet intended for health professionals. [, Hynes KL, Otahal P, Burgess JR, Oddy WH, Hay I. ¼ teaspoon), Pasta, enriched, boiled in water without iodized salt, 1 cup. The researchers also reported a dose-dependent reduction in self-assessed pain. Pasta is not a source of iodine unless it is prepared in water containing iodized salt because it absorbs some of the iodine [11]. In a double-blind study, researchers randomly assigned 56 women with fibrocystic breast disease to receive daily supplements of iodine (70 to 90 mcg I2/kg body weight) or placebo for 6 months [76]. High intakes of iodine can cause some of the same symptoms as iodine deficiency—including goiter, elevated TSH levels, and hypothyroidism—because excess iodine in susceptible individuals inhibits thyroid hormone synthesis and thereby increases TSH stimulation, which can produce goiter [2,80]. Trends and public health implications: iodine excretion data from National Health and Nutrition Examination Surveys I and III (1971-1974 and 1988-1994). Iodine-deficiency disorders. Acute poisoning symptoms include burning of the mouth, throat, and stomach; fever; abdominal pain; nausea; vomiting; diarrhea; weak pulse; and coma [2]. The lethal dose for an adult human is 30 mg/kg, which is about 2.1–2.4 grams for a human weighing 70 to 80 kg (even if experiments on rats demonstrated that these animals could survive after eating a 14000 mg/kg dose). I2 (s) Standard State of Mercury. In humans, the ratio of T4 to T3 released into the blood is between 14:1 and 20:1. The impact of common micronutrient deficiencies on iodine and thyroid metabolism: the evidence from human studies. 2008 Oct 4;372(9645):1251-1262. Iodine status of pregnant women and women of reproductive age in the United States. Under normal conditions, the body tightly controls thyroid hormone concentrations via TSH. In most people, iodine intakes from foods and supplements are unlikely to exceed the UL [2]. Food Addit Contam. More recent NHANES measurements indicate that urinary iodine levels have stabilized in the general U.S. population. [, Charlton KE, Gemming L, Yeatman H, Ma G. Suboptimal iodine status of Australian pregnant women reflects poor knowledge and practices related to iodine nutrition. Chronic iodine deficiency may be associated with an increased risk of the follicular form of thyroid cancer [44]. [89], Iodine accounts for 65% of the molecular weight of T4 and 59% of T3. Unlike low dose iodine and high dose iodine, I do not believe that there is a time or place for the use of very high doses of iodine. Guidance. [, Alexander EK, Pearce EN, Brent GA, Brown RS, Chen H, Dosiou C, et al. A meta-analysis of 6,180 mother-child pairs from three birth cohorts in the Netherlands, Spain, and the United Kingdom found that verbal IQ assessed in children at 1.5 to 8 years of age was lower if their mothers had lower iodine status in their first trimester of pregnancy [42]. [, Pearce EN. )[87][88] It is required for the synthesis of the growth-regulating thyroid hormones thyroxine and triiodothyronine (T4 and T3 respectively, named after their number of iodine atoms). [, Pennington JA, Young BE, Wilson DB. The use of iodized salt is the most widely used strategy to control iodine deficiency. Thyroid. The iodine clock reaction (in which iodine also serves as a test for starch, forming a dark blue complex),[17] is a popular educational demonstration experiment and example of a seemingly oscillating reaction (it is only the concentration of an intermediate product that oscillates). Iodine = I2 , Iodide = I- Iodine can exist freely, but Iodide cannot. [72], About half of all produced iodine goes into various organoiodine compounds, another 15% remains as the pure element, another 15% is used to form potassium iodide, and another 15% for other inorganic iodine compounds. Trials 2015;16:563. Foods high in goitrogens include soy, cassava, and cruciferous vegetables (e.g., cabbage, broccoli, and cauliflower). Effect of iodine supplementation in pregnant women on child neurodevelopment: A randoised, double-blind, placebo-controlled trial. Similarly, the WHO recommends 250 mcg/day during pregnancy and lactation [3]. [, Dasgupta PK, Liu Y, Dyke JV. (iii) Standard state of elements refers to the pure element in its most stable form at 298 K and 100 kPa pressure. [, Hollowell JG, Staehling NW, Hannon WH, Flanders DW, Gunter EW, Maberly GF, Braverman LE, Pino S, Miller DT, Garbe PL, DeLozier DM, Jackson RJ. Women who restrict their dietary salt intake also have lower urinary iodine concentrations and might be more likely to be iodine deficient than women who don’t restrict salt intake [39]. Am J Med 1993;94:524-532. The production of ethylenediamine dihydroiodide, provided as a nutritional supplement for livestock, consumes a large portion of available iodine. Such reactions have led to the misconception (widely held, even among physicians) that some people are allergic to iodine itself; even allergies to iodine-rich seafood have been so construed. It penetrates into microorganisms and attacks particular amino acids (such as cysteine and methionine), nucleotides, and fatty acids, ultimately resulting in cell death. Plant-based beverages used as milk substitutes, such as soy and almond beverages, contain relatively small amounts of iodine. 2009 May;70(5):803-809. (The typical daily dose of iodine for normal health is of order 100 micrograms; see "Dietary Intake" below.) ¼ teaspoon), Pasta, enriched, boiled in water with iodized salt, 1 cup, Fruit cocktail in light syrup, canned, ½ cup, Bread, whole-wheat, made without iodate dough conditioner, 1 slice, Bread, white, enriched, made without iodate dough conditioner, 1 slice, Sea salt, non-iodized, 1.5 g (approx. Dry ice (solid carbon dioxide, which is not an … This iodine database provides food descriptions along with means, standard deviations, value ranges, and sample sizes, with supporting documentation. The FDA has approved potassium iodide as a thyroid-blocking agent to reduce the risk of thyroid cancer in radiation emergencies involving the release of radioactive iodine [77]. When iodide enters the circulation, the thyroid gland concentrates it in appropriate amounts for thyroid hormone synthesis and most of the remaining amount is excreted in the urine [2]. However, multiple 24-hour urinary iodine or multiple spot urine measurements are more accurate for individuals [4,30]. These values, which vary by age and gender [2], include: Table 1 lists the current RDAs for iodine [2]. [, Gowachirapant S, Jaiswal N, Melse-Boonstra A, Galetti V,Stinca S, Mackenzie I, et al. In this cross-sectional study, pregnant women living in Spain had a significantly increased risk of hyperthyrotropinemia (TSH >3 microU/mL) if they consumed iodine supplements in doses ≥200 mcg/day compared with those who consumed doses <100 mcg/day [68]. gas. The US recommended daily intake for iodine is 150 mcg/day for adults, and the FDA’s limit is set at 1 mg/day. Prevention and control of iodine deficiency in pregnant and lactating women and in children less than 2-years-old: conclusions and recommendations of the Technical Consultation. 1996;66(4):350-362. This section focuses on four areas of biomedical research examining iodine’s role in health and disease: fetal and infant development, cognitive function during childhood, fibrocystic breast disease, and radiation-induced thyroid cancer. According to some iodine experts, the requirement of the whole human body for iodine … * Formula and food should be the only sources of iodine for infants. Iodine probably attacks surface proteins of enveloped viruses, and it may also destabilise membrane fatty acids by reacting with unsaturated carbon bonds. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet. The DV for iodine is 150 mcg for adults and children aged 4 years and older [12]. Nauman J, Wolff J. Iodide prophylaxis in Poland after the Chernobyl reactor accident: benefits and risks. For this reason, people at risk of exposure to environmental radioactive iodine (iodine-131) in fallout may be instructed to take non-radioactive potassium iodide tablets. The addition of iodine to table salt has largely eliminated this problem in wealthier nations, but iodine deficiency remains a serious public health problem in the developing world today. In areas where iodide prophylaxis was not used, such as Belarus and Ukraine, where many children were mildly iodine-deficient, the incidence of thyroid cancer sharply increased among children and adolescents [77]. Salt iodization programs, which many countries have implemented, have dramatically reduced the prevalence of iodine deficiency worldwide [2,3]. Copper, Manganese, Selenium, and Iodine, U.S. Food and Drug Administration, Code of Federal Regulations, CFR 21, Sections 184.1634 and 184.1265, National Health and Nutrition Examination Survey Data, Global scorecard of iodine nutrition in 2019, Potassium iodide as a thyroid blocking agent in radiation emergencies, Guidelines for Iodine Prophylaxis following Nuclear Accidents, Bread, whole-wheat, made with iodate dough conditioner, 1 slice, Bread, white, enriched, made with iodate dough conditioner, 1 slice, Iodized table salt, 1.5 g (approx. *DV = Daily Value. [90] The toxicity derives from its oxidizing properties, through which it denaturates proteins (including enzymes). According to the WHO, a median urinary iodine concentration of 150–249 mcg/L indicates adequate iodine nutrition during pregnancy, while values less than 150 mcg/L are considered insufficient [3,7]. The major form of thyroid hormone in the blood is thyroxine (T4), which has a longer half-life than T3. Your thyroid gland, which is … 1990 Nov;90(11):1571-1581. Anti-thyroid medications, such as methimazole (Tapazole®), are used to treat hyperthyroidism. Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA. ... Foods in nutrient-dense forms contain essential vitamins and minerals and also dietary fiber and other naturally occurring substances that may have positive health effects. Includes a variety of protein foods, including seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products. Center for Drug Evaluation and Research, Food and Drug Administration. Studies have also shown that excessive iodine intakes cause thyroiditis and thyroid papillary cancer [2,80]. The FDA has approved the use of potassium iodide and cuprous iodide for salt iodization [19], whereas the WHO recommends the use of potassium iodate due to its greater stability, particularly in warm, damp, or tropical climates [3]. The median iodine content was 150 mcg per daily serving, with a range of 25 to 290 mcg; 25 of the 34 provided iodine as potassium iodide. [, Murray CW, Egan SK, Kim H, Beru N, Bolger PM. Breast milk contains iodine, although concentrations vary based on maternal iodine levels.
