Conditions we support › Thyroid (Hypothyroid / Hashimoto's)
Support your thyroid, energy, and metabolism through food.
When your thyroid is running slow, being told to eat well can feel unhelpfully vague. Here is what actually matters. An underactive thyroid, Hashimoto's included, slows your metabolism and can bring fatigue, weight changes, and more. Food won't replace your thyroid medication. But the right nutrients, like selenium, zinc, iodine, and protein, plus steady blood sugar, really do support how you feel day to day.
Start your Thyroid (Hypothyroid / Hashimoto's) plan →We make sure you get enough protein and the key micronutrients, keep your blood sugar steady for even energy, and lean on anti-inflammatory whole foods. If you have Hashimoto's, the overlap with celiac is real, so it's worth getting tested, and some people choose to try cutting gluten from there.
People with hypothyroidism or Hashimoto's who want to eat in a way that supports their energy, their weight, and the condition itself.
When your thyroid is underactive, the gland isn't making enough of the hormone that sets your metabolic pace, so everything runs a little slow: energy, digestion, mood, weight. Food can't restart the gland, and if you've been prescribed thyroid medication, that medication is doing the essential work. What food can do is two things: make sure your thyroid has the raw materials it needs, and make sure nothing gets in the way of your medication.
On the raw materials, a few minerals matter. Your thyroid can't make hormone without iodine, but this is a Goldilocks nutrient, not a "more is better" one. Too much can actually provoke thyroid trouble, especially with Hashimoto's, so mega-dosing (think kelp pills) is a mistake. That said, the old assumption that everyone gets enough from iodized salt doesn't hold the way it used to. If you reach for sea salt, kosher salt, or pink salt, like a lot of people now do, you're getting little to no added iodine, which makes iodine-containing foods, seafood, dairy, eggs, and a little seaweed, matter more. The aim is enough, not a flood. Selenium is the one people ask about most, and it is worth being precise about what it does. Pooled across the trials, selenium lowers thyroid antibodies on your bloodwork and nudges TSH down a little in people not yet on medication. What it has not been shown to do is change free T4, shrink the gland, or make anyone feel better, and the American Thyroid Association's own read is that the evidence isn't there yet to recommend it for slowing hypothyroidism down. Falling antibodies are not the same thing as a better-working thyroid. So get selenium from food, a Brazil nut or two, seafood, eggs, and leave the high-dose pills alone unless your own provider has a reason to suggest otherwise. Zinc, iron, and vitamin D round out the supporting cast.
The most practical piece is also the most overlooked: timing your medication. Levothyroxine absorbs best on an empty stomach, so the usual advice is to take it 30 to 60 minutes before anything else, and coffee counts as something else: it blunts absorption when it lands at the same time. Calcium, iron and soy supplements are the stricter case, and the standard advice there is four hours' clearance rather than one. Getting that routine right can matter as much as anything on your plate.
A couple of myths worth clearing up. Goitrogens, the compounds in cruciferous vegetables like broccoli and kale and in soy, get a scary reputation, but for almost everyone they're a non-issue. You'd have to eat enormous raw amounts to affect your thyroid, and cooking softens them further, so these genuinely healthy foods stay on the menu. And the bottom line throughout: food supports your thyroid, it doesn't replace your medication or your bloodwork, so keep your levels monitored with the provider who manages your prescription.
Celiac disease turns up several times more often in people with Hashimoto's than in everyone else. Both are autoimmune and they share some of the same genetic ground, so if you have one, the other is worth ruling out. That much you have probably heard. What usually gets left out is the sequence, and the sequence is the part that can cost you.
Ask for the celiac test before you cut gluten, not after. The blood test looks for antibodies your body makes in response to gluten. Take gluten away and those antibodies fade, so the test can come back negative in someone who genuinely has celiac disease. Getting the answer afterward means a supervised gluten challenge: the Celiac Disease Foundation puts that at roughly 3 to 6 grams of gluten a day for twelve weeks, which is months of eating the thing that makes you feel unwell, and it is not something to do while pregnant.
So if you are wondering about gluten, ask for the celiac panel while you are still eating normally. It is a blood draw, and your provider can add it to labs you are already having. If it comes back negative and you still want to see how you feel without gluten, that is a fair experiment to run, and one you can run without having closed a door behind you.
Outside of a celiac diagnosis, there isn't strong evidence that going gluten-free improves thyroid function or antibody levels, so treat it as a personal experiment rather than a rule. And a real celiac diagnosis is worth having on paper rather than guessing at, because it changes more than the grocery list: it means lifelong strict avoidance rather than a preference, it comes with checks on the nutrients that malabsorption depletes, and it is a reason for close family to get screened too. Our celiac plans are built for that, cross-contamination guidance included.
Food supports your thyroid medication. It never replaces it, so take it as prescribed and keep testing with your provider. Hashimoto's often travels with celiac, so if you're wondering about gluten, get the celiac test before you cut it, not after. And the timing of iodine, soy, and supplements around your levothyroxine matters, so ask your provider about that.
