Your thyroid relies on iodine to produce T4 and T3, the hormones that control energy, metabolism, and so many other functions in the body. Without enough iodine, your thyroid can’t work efficiently, which can lead to hypothyroidism, nodules, or even goiter.
But it’s all about balance, too little iodine can slow your thyroid down, while too much can overstimulate it or worsen autoimmune conditions like Hashimoto’s.
This one has been a big learning curve for me; my own iodine levels came back really low, so it’s something I’m now focusing on more intentionally.
Foods that naturally support iodine levels:
- Sea vegetables like kelp, nori, or wakame (in small amounts)
- Iodised salt (used mindfully)
- Fish and seafood such as cod, tuna, and prawns
- Eggs
(TO NAME A FEW)
If your iodine levels are low, it’s best to test before supplementing, as too much can do more harm than good. Working with a practitioner to find the right balance is key.
For me, it’s been about focusing on nourishing foods, supporting my gut health, and reducing stress, all of which help the body better use the nutrients it needs.
