It’s well accepted iodine supplements are effective for preventing and treating an iodine deficiency. They are generally considered safe when taken as recommended.


Iodine Is Essential For Proper Thyroid Function


Nutrient deficiencies are a common issue for those with hypothyroidism. Iodine is one nutrient you don’t want to get low in as the thyroid uses iodine to make your thyroid hormones. This makes iodine important for ongoing thyroid health.


Iodine deficiency can lead to iodine induced hypothyroidism, enlargement of the thyroid, and a reduced ability of the thyroid to produce thyroid hormones.


Are Iodine Supplements For Thyroid Safe?


It turns out there is a vast amount of research in this area including how much iodine is safe to take.


There is one guiding rule that I would like everyone to know.


It’s about balanced intake. Not too much, not too little!


Iodine is normally only required in very small amounts. In fact iodine supplements normally supply trace, or microgram quantities.


When you research iodine supplements online, or thyroid health formulas with iodine, it’s important to know that 1 milligram equals 1,000 micrograms. You may see a microgram measurement abbreviated as ‘mcg’ or ‘µg’ on a label.


Iodine Supplements in Australia Are Strictly Regulated


In Australia all nutritional products are closely regulated by the Therapeutic Goods Administration (TGA), a division of the Department of Health and Ageing.


Nutritional supplements must be approved before being released for sale. Approved products state their individual AUST L or AUST R number on the front of the label.


The active ingredients contained in a product and the recommendations on the label are also closely controlled. The recommended daily intake of iodine from an iodine supplement must not exceed 300 micrograms per day. For example, when a nutritional supplement contains 130 micrograms of iodine it’s recommended that an adult does not take more than two capsules per day.


If an iodine supplement was to contain milligram amounts it would not be approved for sale here in Australia. Even if one tablet, or capsule was recommended per day the recommended intake would be set too high.


In addition to dosing guidelines the TGA provides strict guidelines on the type of iodine that can be used. Iodine is an approved ingredient for use in a nutritional supplement when it is a component of a specific herbal preparation or is in the form of potassium iodide.


For example an iodine supplement can contain Bladderwrack (Fucus vesiculosus), a type of seaweed which is known to naturally contain iodine and is traditionally used to help maintain healthy thyroid function.


Another popular form of iodine featured in thyroid health products is potassium iodide. No other single form of iodine is approved for use in an iodine supplement in Australia.


It’s Vital to Know the Safe Upper Level of Intake


You should avoid taking high doses of iodine for prolonged periods unless you are doing this in consultation with a trusted healthcare practitioner.


Taking iodine in mega doses can pose problems. Taking multiple milligram amounts can saturate your thyroid which can irritate and inflame the gland.


The documented side effects of taking too much iodine include; a metallic taste, sore gums, a burning sensation in the mouth and throat, increased saliva, digestive upset, mood changes and skin problems.


Population studies have also shown excessive iodine intake may trigger autoimmune thyroid disorders.

The Australian National Health and Medical Research Council (NHMRC) and the US National Institutes of Health have both set the recommended safe upper level of intake at 1,100 micrograms per day.


Are USA Iodine Supplements Safe To Buy Online?


When you do a quick search of iodine supplements online you will soon discover there is certainly conflicting opinions and information about how much iodine is safe to take.


For Australian consumers it’s important to know that iodine products available on USA websites are not regulated by the TGA. This government organisation only has jurisdiction within Australia.


It is possible iodine supplements available on USA websites can contain excessive amounts of iodine.


The TGA advises consumers to refrain from ordering nutritional products over the internet unless they know exactly what is in the product, have checked that the ingredients are suitable for them, and the products they are purchasing meet the legal requirements for importation and use in Australia.
