What is iodine?
Iodide is an essential mineral used to create thyroxine (T4) and triiodothyronine (T3), which are the two thyroid hormones that modulate your thyroid system and control your metabolism, heart rate, and female reproductive health.
Is iodide water-soluble or fat-soluble?
Iodine is readily soluble in water. Therefore, your body absorbs it quickly, and it doesn’t tend to build up in your tissues.
Where can iodine be found naturally?
Dietary iodine is most plentiful in seaweed, and this nutrient is also present in dairy and certain types of fish. Since the mid-20th century, most types of table salt have been fortified with iodine.
5 foods/drinks containing iodine
1. Seaweed (up to) 2,000% DV per 1g
2. Cod 66% DV per 85g or 1/5 of 1 fillet
3. Yogurt 50% DV per 1 cup or 128g
4. Milk 37% DV per 1 cup or 128g
5. Shrimp 23% DV per 85g
What is the recommended daily intake for iodine?
According to the National Institutes of Health (NIH), the recommended daily amount (RDA) for iodine is 150mcg. This amount increases to 220mcg for women who are pregnant and 290mcg for women who are lactating.
How much seaweed do I need to take to get a full daily dose of iodine?
Different types of seaweed have different amounts of iodine. A gram of nori, for instance, which is used to make sushi, contains about 25% of your RDA for iodine, but other types of sushi might contain much higher concentrations.
What to consume to get a full daily dose of iodine?
Cod - approximately 125g or 1/3 of a fillet
Yoghurt- approximately 256g
Cow's milk - approximately 3 cups or 384g
Prawns - approximately 340g
Potatoes - approximately 2 medium potatoes
Can you absorb enough of iodine from food?
It’s possible to get enough iodine from food; for omnivores, it’s relatively easy to get this nutrient from dairy products and seafood, and for vegetarians and vegans, nori and other types of seaweed are rich in iodine. This substance is also present in table salt, but it might be easier to know you’re getting your exact DV of iodine by taking supplements.
Why is iodine necessary for your body?
Iodine is a critical component in the operation of your thyroid system. This system, which is centralised in the thyroid gland in your throat, controls most of your bodily functions that have to do with timing. From heart rate to digestive metabolism, your thyroid system makes sure that bodily processes proceed at the correct pace, but without enough iodine, things go awry fast.
Functions of iodine
Thyroid system functions: Without enough thyroid hormone, your thyroid gland will try to work overtime and enlarge. If this gland enlarges to a significant degree, a condition called goiter can occur.
Neurological functions: Adequate thyroid levels support proper neurological development, and they prevent psychiatric conditions.
Hair and skin functions: Proper thyroid hormone levels help maintain your skin and hair health.
Female reproductive functions: Hypothyroidism while pregnant reduces birthweight, and it also increases the likelihood of stillbirth.
Symptoms of iodine deficiency
Severe hypothyroidism causes goiter, which is an enlargement of the thyroid gland that occurs as this organ attempts to produce sufficient levels of thyroid hormone. Severe cases of goiter may require subtotal or total thyroidectomy, which is the surgical removal of the thyroid gland.
When you don’t have enough thyroid hormone, your metabolism decreases, and your likelihood to become overweight or obese increases.
If you feel cold even when the people around you feel warm, you could be suffering from iodine deficiency. This symptom is a common result of hypothyroidism.
How long do you need to take iodine to start experiencing its benefits if you’re deficient?
In most cases, supplementation with iodine can begin to address the symptoms of hypothyroidism almost immediately. In the case of severe deficiency or thyroid disorders, such as Hashimoto’s disease, it may take months or even years for supplementation to result in noticeable beneficial effects.
How long does it take for your body to digest/absorb iodine?
Iodine has an incredibly high absorption rate. According to some estimates, your body may absorb as much as 96.4% of the iodine you consume.
How long does iodine stay in your body after you take it?
The only place where iodine builds up is in your thyroid gland. Otherwise, your body excretes this essential nutrient within 24 hours.
Is iodine an antioxidant?
Medical researchers aren’t quite sure whether iodine is a direct antioxidant. Some research seems to indicate that this mineral directly eliminates reactive oxygen species, and whatever the case may be, it’s clear that iodine is a potent anti-inflammatory substance.
Can you overdose on iodine? What are the effects?
If you overdose on iodine, you could throw your thyroid system out of balance and develop hyperthyroidism. This condition occurs when you have too much thyroid hormone in your system, and symptoms of hyperthyroidism include feeling hot, losing weight, and constant hunger.
Temporary symptoms of mild iodine poisoning include diarrhoea, nausea, and a burning sensation in your mouth. Symptoms of severe iodine poisoning include weak pulse, airway swelling, cyanosis, and coma. Make sure you avoid these symptoms by limiting your daily iodine intake to the RDA for your age and status.
Does iodine dissolve, flush out, or build up in the body?
Most of the iodine you consume flushes out of your body within 24 hours, and a small amount of this element remains in your thyroid gland for significantly longer.
Can you take iodine during a diet?
Taking iodine supplements doesn’t interfere with dietary restrictions, and by treating hypothyroidism, iodine supplementation may even help you lose weight.
Are there synthetic forms of iodine?
It’s practically impossible to synthesise elemental iodine. Forms of iodine which are created in a lab, such as potassium iodide, can technically be called synthetic.
Why might synthetic forms of iodine be better?
Interestingly, one type of treatment for hypothyroidism is the administration of synthetic thyroid hormone. This type of treatment is also used in the case of partial or total thyroidectomy. It’s important to keep in mind, however, that synthetic thyroid hormone and iodine are completely different substances.
Absorption rate of synthetic iodine
A formulation of elemental iodine and would likely have the same high absorption rate as the natural element.
Why might natural forms of iodine be better?
Natural iodine has absorption rates as high as 95%. You can’t get much better than that.
How to take iodine
You can consume iodine in food or in supplement form.
Iodine trends in medicine
A 2019 study demonstrates that iodine treatment shows promise for cutaneous inflammatory disorders, which are debilitating conditions that result in periodic bouts of inflamed skin lesions. Further research will likely discover even more applications of this highly beneficial nutrient.
Why everyone should be taking WeAreFeel supplements
Your thyroid system needs to stay in perfect balance to remain in proper working order. If your thyroid hormone levels stray to either side of the equation, you’ll experience metabolic issues, and you might even need to undergo thyroid surgery.
Unfortunately, many supplements on the market provide far more iodine than you need. Too much iodine can be just as bad as too little of this essential mineral, but here at WeAreFeel, we provide you with exactly 150mcg of iodine in each daily capsule of Feel!
