Kelp reduces autoimmune thyroid cell differentiation
We examined the effects of iodine-rich herbs, like kelp, compared to potassium iodate (PI) on thyroid health in mice with autoimmune thyroiditis.
Our findings showed that iodine-rich herbs posed less risk of oxidative damage and had an improved ability to combat stress compared to PI.
Additionally, these herbs were effective in reducing the differentiation of Th17 cells, which are involved in autoimmune responses. This suggests that incorporating iodine-rich herbs, such as kelp, may offer a safer alternative for supporting thyroid health in those with autoimmune conditions.

This product has successfully addressed my low body temperature issue. After consulting what I needed, I added iodine to my regimen. Within two weeks, my temperature reached 36.6°C! In my iodine-deficient region, a 1000 mcg dosage is perfect. I highly recommend this excellent quality product.

Good iodine option at a dosage of 1000 mcg. Suitable only for those who understand why they need such dosages, so caution is advised. The pack contains 60 standard capsules, and the composition is clear: it provides 1000 mcg of Iodine from a mix of Sea-Iodine™ (organic brown algae and kelp extract, potassium iodide).

Increased vitality

I’ve been ordering this iodine for the last few years for both myself and my wife. We've experienced significant improvements in wellness and energy levels since we began taking it. Given the common iodine deficiency in our area, I find this product far superior to others offered at pharmacies.

Family health improvement

Best Iodine on iHerb! Living in Uzbekistan, where iodine deficiency is common, my whole family takes it daily. The benefits are clear: my mother's neck stopped pinching, and the quality of the drug is quite effective. We order several packages at once, and I appreciate its simple composition of just iodine.

Enhanced energy levels
1 people found this helpful
An excellent drug! Maintaining a proper nutrient balance is quite challenging nowadays, with the food and environment conditions. After consulting my doctor, I ordered iodine from iHerb, feeling unwell due to an obvious deficiency. Within a week and a half, I noticed improvements; I felt cheerier, woke up more easily, and no longer needed excessive coffee to stay alert. The joint intake with selenium positively impacted my hair as well. I highly recommend it!

Hair loss improvement

Great for iodine deficiency. My doctor prescribed this drug due to my active hair loss and my analysis showed Iodine deficiency. After the first course, I noticed reduced hair fall. Subsequent reanalysis indicated improvement, making this purchase successful. I plan to continue ordering these vitamins.

Thyroid improvement
13 people found this helpful
Working iodine! I ordered it a second time as I clearly feel the effects. For years, the skin on my elbow has been dark and rough, indicating thyroid disease. After taking this iodine for the first time, my skin became smooth and returned to a normal colour. Highly recommended. The capsules are small and easy to take.

Relief from fibroids
1 people found this helpful
I’m using it for breast fibroids and believe in the power of natural healing. Once my first bottle finished, my breasts became softer, and I could hardly feel the fibroids. After a month hiatus and trying a different iodine, I feel the fibroid returning, hence I've ordered my second bottle, hoping it does the trick again.

Nail texture enhancement

I've ordered it for the second time for my Hashimoto's. I take half a capsule with selenium and plan to increase the dosage to a whole capsule. I've noticed my nails have become smoother since using iodine.

Optimally dosed
1 people found this helpful
Though the dosage is high, it's optimal for those away from the sea. It greatly aids my thyroid function, but it's wise to consult a doctor beforehand. The small capsules are easy to swallow, and I’ve noticed improved levels of TSH. Quality product!

Skin reaction noted

I ordered this for my husband to support his immunity during spring illnesses. Unfortunately, on about the fifth day, he developed rashes throughout his body, leading us to stop his intake.

Awoke refreshed

Following my endocrinologist’s advice, I started with one capsule every other day and increased to one daily with no side effects. Now, I wake up feeling vigorous and well-rested rather than sluggish, as I did before taking iodine.
