Iodine is used to treat and prevent iodine deficiency and as an antiseptic. For iodine deficiency it can be given by mouth or injection into a muscle. As an antiseptic it may be used on wounds that are wet or to disinfect the skin before surgery. [Reference: Wikipedia]

What Are Iodine ​Supplements?

Iodine supplements are simply capsules, pills or liquid drops that help supply you with iodine. This helps ensure that you get enough on a daily basis, which can improve your health in a number of ways.

Iodine tablets or capsules are the most popular, offering a concentrated dose in powdered form for easy absorption and digestion. Iodine drops, packaged in small bottles with droppers, offer higher potency, albeit at the cost of less convenience.

What Are the Benefits of Iodine?

Iodine serves a number of important roles in the human body. Millions of people worldwide suffer from iodine deficiency, and it causes serious health problems.

The benefits of iodine are primarily seen in people who begin taking supplements when they are deficient in the nutrient – in other words, if you get enough iodine from your regular diet, you likely won’t see as much positive benefit from these supplements.

One of iodine’s key roles in the body is supporting the thyroid. Without it, the thyroid struggles to make hormones. This can lead to the body pushing the thyroid to work harder and harder, which can lead to health problems including goiter. The thyroid also plays a key role in energy production, metabolic rate, and more.

In addition to affecting how the thyroid works, iodine plays a key role in many other aspects of health. A lack of sufficient iodine in your system can cause hypothyroidism, which can lead to low energy levels, weight gain, dry skin, higher cholesterol, and a number of other serious health concerns.

During pregnancy, iodine intake is especially important. Iodine deficiency is common during pregnancy, and it can cause some very serious repercussions for both you and your child. A lack of this key nutrient during pregnancy can lead to stunted growth (both mental & physical), mental deficiencies, and even quadriplegia and deafness.

OUR TOP PICK

Life Extension Sea-Iodine Capsules, 1000 mcg, 60 Count, Package may vary

We just love these sea-iodine capsules from Life Extension.

It’s very very affordable for one. 

What we love about it is that it’s safe for vegetarians. Although it’s clearly from the sea, it is in fact harvested from a blend of marine algae, which is all organic, and not genetically modified in any way. So you get important nutrients derived from the sea, but all sourced without endangering any animals.

One tablet provides a dosage of 1000 mcg, which is quite potent and significant. Most people only need about 150 mcg per day. And it’s advised not to go over 1100 mcg per day.

It’s available in different size bottles. A small one will last just under 2 months, the medium will last just over 3 months, or you can buy the big bottle which will last you about 5 months, give or take.

This brand also offers sea-iodine capsules in combination with certain vitamins, specifically vitamins D, K, and D3. But to keep things simple, the link we’ve provided takes you to a bottle containing just sea-iodine capsules alone.

Pros:

  • Large dose per tablet
  • Safe for vegetarians
  • Very affordable

Cons:

  • Almost unsafe dosage

EDITOR'S CHOICE

J.CROW'S® Lugol's Solution of Iodine 2% 2oz

This little bottle of iodine solution is rated as a best seller with online retailers in the iodine mineral supplement category. And rightly so.

Having the supplement in a liquid form, as opposed to a more solid form, such as a tablet, makes it far easier for the body to digest and distribute as needed through the body.

It not only contains iodine but also contains potassium iodide too. One drop of the solution contains 1 mg of iodine and 2 mg of potassium iodide. This means that in just drops of solution you get a full 5 mg of iodine/iodide solution.

We love how it’s sourced. It’s not derived from shellfish, but is actually mined right here in the USA, from 320 million year old natural brine deposits situated two miles beneath the earth's surface.

And the remaining solution is pure distilled New Hampshire spring water. All good, premium, natural ingredients.

We like the fact that there’s no expiration date to worry about.  It keeps fresh indefinitely, without the need to even refrigerate it.

It’s also quite the little money saver compared to it’s tablet form counterpart.

Pros:

  • Liquid form
  • No expiration date
  • Sourced in USA

Cons:

  • You have to store it out of direct sunlight

  • To use as a water purifier add 3-6 drops per liter of water

BEST VALUE

NOW Supplements, Kelp 325 mcg of Natural Iodine, Supports Healthy Thyroid Function*, Super Green, 250 Veg Capsules

Now, this is a great brand for supplements (pardon the pun).

You get a whopping 250 tablets in a bottle - that’s enough to last you over 8 months. And when it’s this price, that’s phenomenal value for money.

The daily dosage is set at 325 mcg, which is sufficient enough, not just for the everyday Joe, but also for pregnant women and breastfeeding women, who need that bit extra. And at the same time, the dosage is much lower than would be dangerous, so there’s very little danger of taking too much.

This natural iodine supplement is suitable for both vegetarians and vegans. And that’s because it’s derived from kelp, which is a large, leafy seaweed from the colder waters of the world's oceans. It’s been used as a staple ingredient in Chinese, Japanese, and Korean cuisines for centuries.

It’s free of any artificial ingredients or allergens and there are no hidden nasties whatsoever to worry about.

The capsules are quite big to try and swallow, if you don’t like taking tablets, but on the plus side, there is a very easy to swallow coating on it.

Pros:

  • Great value for money
  • Nice dosage
  • Suitable for vegetarians & vegans
  • No hidden nasties

Cons:

  • The tablets are quite large to swallow

Liquid Iodine Potassium Drops - 1300 Servings | Large 2oz Bottle | Great Taste | 2X Absorption | Just One (1) Drop a Day for Fast, Potent Thyroid Support - Potassium Iodide. Alcohol and Gluten Free

This liquid iodine comes highly recommended, and provides a very precise amount of iodine in each dosage, 150 mcg to be exact (in the form of potassium iodide). But at the same time, the dose can be easily modified if you want to take two more drops instead of just the one.

One drop per day is enough in most cases, unless you’re pregnant or lactating. So one two ounce bottle should provide a total of 1300 servings, so it will really last a long time, and prove excellent value for money in the long run.

It’s a high potency formula, and because it’s in a liquid form rather than tablet or capsule form, it will absorb twice as fast into the body and into the bloodstream.  It will go straight to where you need it at your thyroid gland.

It’s 100 percent vegetarian and vegan. That’s not all though - it’s also sugar free, gluten free and alcohol free to boot.

We think it taste’s ok, but if you’re not too keen on the taste, you can always add it to a drink to disguise the taste.

And it’s made right here in the good old US of A, where it's certified against all the important standards so you know you’re getting the real thing.

Pros:

  • Suitable for vegetarians & vegans
  • Fast absorption into the body
  • Excellent value for money

Cons:

  • Premium product at a premium price

Nascent Iodine Supplement - High Potency Liquid Drops for Thyroid Support to Improve Energy & More - Iodine Edge -30 ml (1.0 fl oz)

This is a great iodine supplement, in the form of nascent iodine drops. Which makes it a great choice if you’ve been told to avoid iodine in it’s potassium iodide form.

What we like the most about this one is the taste. It’s appealingly sweet with being too sweet.

It offers a very high potency in each dose, which is rapidly absorbed into the bloodstream, thanks to it being in liquid form rather than capsule form. And you don’t get any of the fillers or binders you’d get with a tablet or capsule.

The main drawback to this one is the high cost for such a small bottle. Plus you’re supposed to take 6 drops per day, so the bottle will soon get used up and you’ll have to buy new.

Again, it’s suitable for vegetarians and vegans, and is also Kosher certified to boot.

It’s available with a money back guarantee, which is good to know. Not that we think you’ll want to use it, judging by the customer feedback it's had so far.

Pros:

  • Suitable for vegetarians & vegans
  • Doesn’t contain potassium
  • Very high potency per dose

Cons:

  • Comes in quite a small bottle
  • Premium product at a premium price

What we like about this particular product is that one bottle can last for over an entire year, which makes it incredibly good value for money. One bottle provides a whopping 450 servings.

The dosage is quite high as well. You get 250 mcg in just one dose, which is enough even for pregnant women. (Though if you’re breastfeeding you could do with a little more.)
