Why Iodine Deserves Your Attention
Iodine isn’t the flashiest mineral on your supplement shelf, but it’s absolutely essential. Think of it as the unsung hero of thyroid health a quiet operator that keeps your metabolism, energy, and hormonal balance in check. But what happens when you don’t get enough? That’s when things start to unravel.
Let’s break down why is it crucial for your thyroid and what your body might be trying to tell you when it’s running low.
What Iodine Actually Does
Your thyroid gland a butterfly-shaped organ at the base of your neck relies on it to produce two hormones: triiodothyronine (T3) and thyroxine (T4). These hormones regulate your metabolism, body temperature, heart rate, and much more.
Without enough, your thyroid can’t make enough T3 and T4. That’s when you start to feel off: fatigued, sluggish, maybe even depressed. Over time, this can lead to hypothyroidism, a condition that slows down your entire system.
How Iodine Deficiency Affects the Body
So, what actually happens when you're not getting enough?
1. Fatigue and Brain Fog
Low thyroid hormone levels slow your metabolism and brain activity, leading to chronic fatigue and difficulty focusing.
2. Weight Gain
When your thyroid slows down, so does your metabolism. Even if your eating habits haven’t changed, weight gain can sneak up on you.
3. Cold Sensitivity
A common and often overlooked symptom—if you’re constantly bundled up and still freezing, low thyroid hormone production may be to blame.
4. Hair Thinning and Dry Skin
Both are signs that your metabolism has taken a hit and your cells aren’t regenerating as quickly as they should.
5. Goiter (Thyroid Enlargement)
One of the most visible signs of deficiency is a goiter—a swelling at the base of the neck caused by an overworked thyroid trying to compensate for a lack of raw materials.
Who’s at Risk of Low Levels?
In many countries, deficiency used to be common before iodized salt became a kitchen staple. However, people are now using less table salt and opting for sea salt or specialty salts that aren’t iodized. Combine that with dietary restrictions, and you’ve got a recipe for suboptimal intake.
Here are some groups at higher risk:
- People on low-salt diets
- Pregnant or breastfeeding women (it needs increase during these times)
- Vegetarians and vegans (plant-based diets can be low in natural sources)
- People who avoid dairy or seafood
Natural Sources
If you're not a fan of iodized salt, don’t worry—there are other options. Here are some foods you can add to your diet:
- Seaweed: One of the most potent natural sources
- Cod and tuna: High in it and lean protein
- Dairy: Milk, cheese, and yogurt are good sources
- Eggs: Particularly the yolk
- Iodized salt: The easiest way to meet your daily needs
But remember: moderation is key. Too much can also affect thyroid function, particularly if you already have a thyroid disorder.
Should You Supplement with It?
If you're not getting enough through food, a supplement might help. But it's best not to guess get your levels checked with a healthcare provider. Some high-quality supplements offer it in appropriate doses that support your thyroid without going overboard.

Final Thoughts
Your thyroid does a lot behind the scenes, and it can’t function properly without enough. If you’ve been feeling sluggish, cold, or just not like yourself lately, it might be time to consider whether your thyroid has what it needs to thrive.
Supporting your body starts with giving it the right tools and it is one of the most fundamental tools in your thyroid’s toolbox.
