Iodine deficient areas linked to Hyperthyroidism/nodules in China, which shows that Iodine levels are essential for both hyper and hypo thyroidism associated with nodular growths. “Subclinical hyperthyroidism and overt hyperthyroidism are more likely to be prevalent in the iodine deficient areas than in the iodine excess or sufficient areas.”
Why Salt is not enough: Clearing the Iodine confusion by Pharmacist Suzy Cohen “There’s mass confusion and paranoia about iodine, and that’s what prompted me to write today’s article. It actually dawned on me last night (while talking to a person with Hashimoto’s thyroiditis) that iodine is used all over your body. She thought it was just used by your thyroid and read someone’s blog about it, and became very afraid to take it. It’s in salt, the “iodized” salt, but that is not nearly enough iodine for many of you.”
Increasing Iodine dosages to eliminate low dose iodine reactions: “I think that you have to take upwards of 100mg of iodine or higher for the body to make this. Because when I take 25mg, I have horrible detox symptoms, but when I take 100mg of iodine I feel normal. I think that at 100mg and up, the body makes delta-iodolactone, and this [is an] antioxidant . It’s the only thing that can account for the fact that people, who can’t take 25mgs without getting sick, can take 150mg without a problem”. A different perspective, with many patient comments saying they have experienced the same issues, being unable to slowly increase, but coping extremely well. (Please note, we are NOT recommending everyone suddenly jump up their Iodine, but it is good reading to hear other patients experiences and up and coming health info trends based on actual patient experiences)
The role of selenium, vitamin C, and zinc in benign thyroid diseases and of selenium in malignant thyroid diseases: Low selenium levels are found in subacute and silent thyroiditis and in papillary and follicular carcinoma. Thyroid physiology is closely related to oxidative changes. The aim of this controlled study was to evaluate the levels of nutritional anti-oxidants such as vitamin C, zinc (Zn) and selenium (Se), and to investigate any association of them with parameters of thyroid function and pathology including benign and malignant thyroid diseases.
Effect of selenium supplementation in hypothyroid subjects of an iodine and selenium deficient area: the possible danger of indiscriminate supplementation of iodine-deficient subjects with selenium. Basically, taking any key thyroid nutrient by itself without full case assessment and proper treatment in dangerous. In this case study, it shows how selenium, a key thyroid nutrient may exacerbate hypothyroidism when and Iodine deficiency is present. And if that’s not enough about Selenium, here is some more extensive references to go along with it:

SALT TYPES and RESOURCES
Salt Your Way to Health: Book by Dr David Brownstein “For years, we have heard the following: A low-salt diet is healthy. There is no difference between table salt and sea salt. Low-salt products are better for you. These are the myths of salt. Dr. Brownstein will present the research on salt that will change the way you look at this vital substance”
Iodized salt found to be inefficient in correcting iodine levels in lactating women, a study assessing multiple countries and 42 clinical studies that cites “within the iodine deficiency range, indicating that iodine supplementation in daily prenatal vitamin/mineral supplements in lactating mothers is warranted”

What’s Blocking Your thyroid? Free tips from our Head Naturopath Kimberly Orbons in this 6min YouTube video
Checking your own Thyroid by Temperature According to Dr. Broda Barnes: A reading below the normal 98 (after adding 1 degree to under the arm temperature) strongly suggests hypothyroid. A reading above 98.2 may indicate hyperthyroidism (overactive thyroid). (For us Aussies: 98 °F = 36.67 °C The conversion formula is °C = 5/9 (°F – 32)
Herbs like Withania can increase Thyroid metabolism in 8 weeks: “Subtle changes in thyroid indices during a placebo-controlled study of an extract of Withania somnifera in persons with bipolar disorder”
DRUGS AND PHARMACEUTICALS
Avoid Dangerous Interactions When Taking Supplements, by Pharmacist Suzy Cohen 18/06/2015
“We are better off getting our nutrients from healthy foods and beverages, but dietary supplements can fill a nutritional gap. It’s confusing to know when you should take certain nutrients, especially the minerals which can bind or “chelate” with a lot of different medications. It’s also difficult to time your supplements around meals and medications. Over the years, I’ve used my own vitamin list to help me remember when and how to take supplements.”
The Statin Disaster, book by Dr David Brownstein “Statins are the most profitable drugs in the history of Big Pharma. Statins fail to prevent or treat heart disease for almost everyone who takes them and they are causing more harm than any other class of medications. In fact, statins are effective for approximately 1% who take them. In other words, statins fail 99% who take them”
“Serotonin reuptake inhibitors may also alter T4 requirements. In nine patients receiving thyroxine therapy, an elevation in thyrotropin levels and a reduction in FT4 levels were noted after the addition of sertraline hydrochloride.” Gittoes NJ, Franklyn JA. Drug-induced thyroid disorders. Drug Saf 1995; 13:46-55. [PubMed]
“Several medications, including iron, aluminum-containing products (such as sucralfate, antacids, and didanosine), ferrous fumerate, sodium polystyrene sulfonate, resin binders, and calcium carbonate have been reported to impair the absorption of exogenous thyroxine and decrease its efficacy.”

“Hypothyroidism and subclinical hypothyroidism have been reported in 5% to 20% and as high as 50% of people taking lithium carbonate. A twofold increase in the incidence of thyroid antibodies has been found in patients treated with lithium (24%) compared with those not taking lithium (12%). Lithium-induced hypothyroidism is more frequent in those taking lithium for more than 2 years.”

“Therefore, normal FT4 and T3 levels in a patient taking amiodarone are highly suggestive of overt thyroid dysfunction.” AND “Propranolol hydrochloride (>160 mg/d), atenolol, and metoprolol tartrate produce small reductions in total T3 levels.” from http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1070767/

CHEMICALS / PESTICIDES / HEAVY METALS
Heavy metals may be directly linked to the onset and development of Diabetes in this clinical study, in particular arsenic, cadmium and lead,
Perchlorates can cause Hypothyroidism by Pharmacist Suzy Cohen “This pervasive toxin attacks thyroid function. Thyroid hormone gives you energy, improves mood, regulates heart rhythm, stimulates hair growth and helps you burn fat. When you drink or eat contaminated foods with perchlorates, they compete with iodine preventing uptake, and this reduces thyroid function. We know for a fact perchlorates inhibit the “sodium-iodide symporter” and perchlorates are sometimes injected intravenously into people in order to test them for Hashimoto’s thyroiditis”
Copper Toxicity and Deficiency “Many adjustments you can make in your life, can have a profound effect in minimizing your copper related symptoms. Avoiding the primary sources of copper from foods and the environment is always a great start. Limiting your exposure will make you feel so much better if you have high levels or increasing them if your levels are very low. So, if you are not sure what your levels are, but suspect you have an issue with copper – you need to get it checked”
Why Good Water Filters = Healthier Thyroids! “In order to maintain adequate hydration of the body, our cells and tissues require pure water, free from chemicals and toxins. Standard drinking tap water is likened to a chemical cocktail of harmful, destructive components that do little for our hydration or state of overall health. One of the most detrimental effects these chemicals can have is creating thyroid dysfunction“
FATS / OILS / CHOLESTEROL
Effects of Thyroid dysfunction on lipid profile Published online 2011 Feb 24 “Thyroid dysfunction has a great impact on lipids as well as a number of other cardiovascular risk factors. Hypothyroidism is relatively common and is associated with an unfavorable effect on lipids. Substitution therapy is beneficial for patients with overt hypothyroidism, improving lipid profile. However, whether subclinical hypothyroidism should be treated or not is a matter of debate. On the other hand, hyperthyroidism can be associated with acquired hypocholesterolemia or unexplained improvement of lipid profile. Overall, thyroid dysfunction should be taken into account when evaluating and treating dyslipidemic patients.”
Grass fed beef: Clinical data showing increased carotenoids, and lower bad fats. These modern trends aren’t made up facts from a random blogger. Grass fed meat really does contain higher nutritional value and lower health risks. Other articles on this topic include those by the Mayo Clinic and Chris Kresser.
The Skinny on Fats, book by Dr David Brownstein “Brownstein and Shenefelt challenge the dietary misinformation of our age – that cholesterol and animal fats are bad for us – in this well organized and easy to understand book. ‘The Skinny on Fats’ will enlighten and educate, and will help you overcome your fear of good fats like butter, cream, egg yolks and lard. Highly recommended.” ~ Sally Fallon Morell, President, The Weston A. Price Foundation
