Best Iodine Supplement – October, 2018 Reviews & Buyers Guide

Iodine is an essential mineral. It’s most commonly spoken about in regards to table salt but it much more important than a seasoning, as it plays a vital role in our health. Many people are deficient in iodine and don’t know it.

This mineral is especially essential for the function of the thyroid. Your thyroid helps to regulate various other functions in the body, chief among them is your metabolism. As the only organ that can absorb iodine, it expects to get adequate amounts from your diet. That’s not always the case.

An excellent source of iodine can be found naturally in diets, especially those rich in seafood. For people who don’t eat fish or dairy, you may yourself deficient of iodine. Iodine deficiencies can cause a range of different health issues, from weight gain to fatigue or constipation. Taking supplements is one of the best ways to get the right levels without oversalting your food.

Information Every Informed Buyer Should Know when looking for an Iodine Supplement

The daily recommended dose of iodine for healthy adults is 150 mcg. For women who are pregnant or nursing, that increases to at least 220 mcg, as they are also supporting their child’s intake. Any more than that is excessive unless your doctor deems it necessary.

There are also other cases in which you may be advised to take much more. Those suffering from hormonal or thyroid problems, or even certain types of cancer can benefit from higher amounts. Depending on what your needs are, you can accurately decide how potent you need it to be.

Optimox Iodoral Iodine

Many customers compare Relentless Improvement’s formula to the original potent iodine: Iodoral. Buying this brand will give you the exact same iodine as many other brands. It is iodine derived from potassium iodine without the use of any other minerals.

Although a similar formula, it is a much higher dosage than most. Each tablet packs in 50mg of iodine. Doctors will often prescribe or recommend doses this high for patients experiencing hypothyroidism.

The strength of these tablets is likely why it is priced so high. You only get 30 tablets, but if you need more than that other options may prove to be more cost-effective.

Pros and Cons

  • High potency
  • Much more expensive than most
See Product Details on Amazon

Pure Horizon IOPlus

This iodine supplement uses a few other supplements to aid in its potency. It provides selenium, which is believed to be the second most important mineral for promoting thyroid health. Next in line is vitamin B2. Both of these ingredients are used in this formula of 12.5 mg Iodine.

They specify that this is niacin-free, which is a vitamin also known as B3. Unlike B2, niacin can contribute to the blockage of essential minerals to the thyroid, leading to health problems. These capsules are also made with magnesium stearate, which could have adverse effects for some.

Overall, the pill is small and easy to swallow, reasonably priced, and a long-lasting supply. You’ll get 60 tablets in this bottle, and recommended to take one daily. It’s made in the USA, free of GMOs, and vegan.

Pros and Cons

  • Made in the USA-Also uses selenium and B2-Vegan tablets
  • Contains magnesium stearate
See Product Details on Amazon

Relentless Improvement High Potency Iodine

The name itself is very powerful. This “high potency” iodine from Relentless Improvement is 12.5 mg of iodine sourced from 16.75 mg of iodine potassium. This would be an excellent source for those who need to exceed daily values.

For such a strong name, they’re quite gentle. These tablets are coated with a pharmaceutical glaze for easy swallowing. They don’t use any other fillers or additives. They’re completely vegan.

This cost-effective option comes from a family-owned and operated company. You can ensure that you get what they guarantee, directly from them. There’s no money-back guarantee, but they give you 180 capsules for much less than many other brands.

Pros and Cons

  • Vegan-Family owned
  • Glazed tablets
See Product Details on Amazon

Pure Encapsulations Iodine

As an alternative to the huge portion of iodine, you’ll get with the previous products, this capsule provides the standard recommended daily value of iodine to maintain a healthy thyroid. This product gives you a small, 225mcg dosage of iodine in a 4-month supply.

Its price is relatively higher, being much less in dosage although much higher in supply. The smaller dose is almost certainly the way to go for those who want to reach their daily intake, as opposed to as part of a treatment for thyroid.

These capsules are certified gluten-free, vegetarian, and free of allergens or artificial additives. Natural Encapsulations uses natural ingredients to source their supplements. The brand also ensures they are hypoallergenic, so no patient or customer should experience adverse effects.

Pros and Cons

  • Certified gluten-free-4 month supply
  • More expensive per pill
See Product Details on Amazon

RLC Labs I-thyroid Iodine

These capsules use iodide, iodine, and potassium to give you the thyroid triple threat. Iodine is often derived from Potassium Iodide, as it’s extracted from it and absorbed by the thyroid. The various forms of Iodide and Iodine in a supplement all contribute to its overall potency.

This is another pill to take if you are dangerously deficient and need more than what is recommended daily. Each capsule is 12.5 mg which is astronomical compared to what we’ve seen so far. However, many people who suffer from iodine deficiencies need this for support.

This brand is angled toward those who need help with their thyroid. It is an excellent source of iodine at a very affordable price. It is a vegetarian capsule, but some customers seemed to have trouble that they include magnesium stearate. Talk to your doctor.

Pros and Cons

  • Huge dosage for a great price
  • Contains magnesium stearate
See Product Details on Amazon

Life Extension Sea-Iodine

Derived from organic sea algae, this iodine supplement gives you 1,000 mcg of iodine per serving. The capsules are vegetarian, made from the very commonly used vegetable cellulose and stearic acid.

They focus on giving you kelp-derived iodine for up to 2 months. It doesn’t include many other ingredients or minerals as supplements often like to stack. It does use some potassium iodide for filtering the proper iodine for the thyroid to absorb.

This brand is a popular choice among consumers, especially for this product. It’s a very budget-friendly supplement. It is commonly used for people who need a little extra iodine than normal, as it is more than the daily recommended value.

Pros and Cons

  • Very affordable
  • Far more than the daily- recommended for both
  • Does not specify vegan
See Product Details on Amazon

Natural Nutra Kelp with Iodine

This recyclable glass bottle is another wholesome version of iodine derived from sea kelp. Since it’s in a relatively low dose, 225 mcg, it’s safe for most people as a supplement to their diet to maintain daily iodine goals.

It’s a great deal for a 100 vegetarian capsules. There are many brands who charge much more for a lesser supply. They also offer you the opportunity to return it within 30 days and receive your money back.

The added bonus with this product is their environmental approach. Instead of plastic, they use amber-colored, BPA-free glass. It’s recyclable, and the tint will ensure your product remains pure and unspoiled.

Pros and Cons

  • Vegan and gluten-free
  • 30-day money back guarantee
  • Uses magnesium stearate
See Product Details on Amazon

Dr. Mercola Premium Iodine

Most of the time, iodine is put into tablet-form for supplements. Whether it was coated or uncoated, that is much of what we looked at already. Dr. Mercola found a way to create a capsule supplement for those who prefer it but have had trouble finding it.

These licap-capsules are designed to avoid oxidation of the iodine when encapsulating it - something that might alter the potency. It also helps to preserve the shelf-life. They are securely sealed to avoid any leakage.

This is a somewhat modest dose. It’s ideal for vegetarians or those who don’t have a richly iodized diet. Overall, because of the technology in the capsule, you’ll end up paying a little more than most for a 30-capsule supply.

Pros and Cons

  • One of the only capsules for iodine
  • Pricier than many
See Product Details on Amazon

Puritan’s Pride Premium Sea Kelp with Iodine

For some, like vegetarians, who don’t get enough iodine through their diets, they rely on supplements. Supplements should be able to provide just what you need and not a lot of excesses.

For vegetarians, this is an excellent choice for a daily supplement. It provides 150mcg no more or less than 100% of the recommended value. Even if you think you aren’t deficient, you may find that your energy and metabolism benefits from putting it into your diet.

These capsules are made in the USA by an experienced provider. This brand has been in the supplement business for 40 years, and they’re entrusted to many different supplements. They are so sure of their quality they offer you a money-back guarantee.

Pros and Cons

  • Money-back guarantee
  • Not enough for people who need to take extra iodine
See Product Details on Amazon

Thorne Iodine & Tyrosine

For another household name with a more balanced offering, there’s Thorne. This brand has been a US brand for the past 30 years, recently sponsoring the US gymnastics team.

This product is more of the daily-value oriented type but can be taken in larger doses for those who need potency. The capsules are 225 micrograms and include 500mg of tyrosine for further aid in adrenal functionality.

A bottle will provide 60 capsules. It is very cost effective, and with this brand, you can count on purity. It’s stearate-free as well as gluten-free, dairy-free, and nut-free. You can count on Thorne to provide an additive-free capsule.

Pros and Cons

  • Stearate-free
  • Free of all artificial additives
  • Not the absolute cheapest

Final Thoughts

Iodine is an underdog in the nutritional cannon. Too few people talk about the necessity of iodine in our diets. This is represented by the 70% of the population that is deficient in this necessary mineral!

A supplement is a no-brainer to the question. It can help you improve your energy, sharpen your mind, and strengthen your bones. In some of the most intense situations, it can help to protect against radiation.

It’s more sparse than some might believe in your diet. Many people are drawn to using other salts, like Himalayan salt, and it will provide the same minerals. There is a difference between iodized salt and other sea salts, and only iodized salt provides the necessary nutrition.

The doses vary greatly, so this is an excellent opportunity to say “talk to your doctor.” You should always consult with a healthcare provider before implementing new supplements into your diet, especially in the case of iodine which has such a broad spectrum of dosing.
