Hypothyroidism: Vitamins, Foods, and Beverages to Avoid
June 21, 2025 - In people who are more prone to thyroid disease, this may trigger or worsen inflammation that may lead to Hashimoto’s thyroiditis, a type of hypothyroidism caused by an autoimmune reaction. ... Similar to iron and calcium supplements, some evidence suggests that certain foods and beverages may interfere with the absorption of levothyroxine. ... It’s important to point out that the evidence for some of these is rather limited or conflicting. For example, some studies have found that soy has little clinical impact on levothyroxine absorption, and avoiding it has few proven benefits.

what vitamins do you take and why?
I'm taking vitamin D, a vitamin B complex (which includes b12 and vit c), selenium and magnesium. Selenium is good for thyroid health. Magnesium is good for the nervous system, bone health and heart health. None of them interfere with levothyroxine, and yes its safe to take them daily if you don't exceed the recommended daily limit. One thing to mention: if you take a supplement with biotin in it (most B complexes have biotin in) it can mess up your thyroid blood tests and make them inaccurate. Don't take it for a week before having a blood test. More on reddit.com

best supplements?
Iron, ferritin, D3, B12 and folate are commonly all low with hypothyroidism. To fix the iron you need to test first, and only supplement if you're deficient (ferritin below 50 = deficient), then re-test 6 months and a year later to insure you're in the optimal range (50-100 ferritin) and not headed for toxic levels. That's true with supplementing any of the metals, including selenium that you'll see mentioned here frequently. It's pretty rare that anyone is low in selenium. The others you can safely supplement without testing, as you'll generally just pee out any excess. You can take 1000-2000IU of D3, 25mcg B12, and up to 400mcg of folate without testing. Getting my ferritin in range gave me more symptomatic relief from fatigue than anything the levothyroxine did, by far. edit: Why can't you take biotin? It won't hurt anything for most people. Yes, it CAN screw with thyroid test results, but simply stop taking it 3 days before you have blood drawn, and it's fine. More on reddit.com

Some studies indicate that drinking up to 4 cups of coffee per day might actually improve your thyroid function and lower your risk for mild hypothyroidism. But another study found that drinking 200 mg (about 2 cups or less) of coffee daily is linked to lower levels of certain thyroid hormones. More studies are needed to understand exactly how coffee affects thyroid hormones.

Levothyroxine is taken to replace the missing thyroid hormone thyroxine. Levothyroxine is only available on prescription. It comes as tablets or as a liquid that you swallow. Levothyroxine is a synthetic version of a hormone called thyroxine. It replaces thyroxine if your thyroid gland cannot produce it and prevents the symptoms of hypothyroidism.
