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.

Family health improvement
5 people found this helpful
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.

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.

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.

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!
