“Thyroid support” supplements contain significant amounts of thyroid hormone
October 8, 2013 - Many of these supplements are used with the idea that they may provide energy or weight loss, although most claims in this regard are unproven. Since symptoms of hypothyroidism may include fatigue and weight gain, a number of supplements are marketed for the purpose of “thyroid support”, to maintain thyroid health and to help the thyroid to function better.

Supplements to help manage hypothyroidism
Not really anything that directly affects the thyroid. Did you do any test for vitamins and minerals? Specifically iron/ferritin vitamins D, B? We are often deficient in them and they have very similar symptoms and will make your symptoms worse. More on reddit.com

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

What causes hypothyroidism?
The most common cause of hypothyroidism is an autoimmune condition known as Hashimoto’s thyroiditis . Other causes include thyroid surgery, radiation treatment, and medications, as well as anything that causes inflammation to the thyroid gland. Sometimes, hypothyroidism is caused by a thyroid deficiency that’s present at birth. This is called congenital hypothyroidism.

Are there any vitamins I should avoid if I have hypothyroidism?
There are no vitamins you should avoid if you have hypothyroidism. But if your hypothyroidism is treated with levothyroxine, you should avoid taking certain vitamins around the same time as your medicine. That’s because these vitamins can interfere with how your body absorbs levothyroxine. Vitamins that lower the absorption of levothyroxine include calcium, aluminum, iron, and magnesium.

What foods or drinks should I avoid with hypothyroidism?
You don’t need to avoid specific drinks or foods if you have hypothyroidism. Some people believe you should avoid certain foods — known as goitrogens — because they can affect your thyroid levels if you’re low in iodine. These foods include lima beans, sweet potatoes, and cruciferous vegetables . But iodine deficiency is very rare in the U.S. So most people don’t need to avoid eating these foods.

June 7, 2024 - Ginseng: A 2018 systematic review of 10 studies found that ginseng improved fatigue, a symptom often associated with thyroid dysfunction 23. Rhodiola: A 2009 randomized controlled trial found that rhodiola improved stress-related symptoms and thinking ability 24. For my hypothyroid clients with lingering fatigue, I might recommend adrenal support for 2–3 weeks. If they don’t have noticeable improvements in energy, mood, and sleep, then they probably don’t need adrenal support. The effect of hydrochloric acid supplements like betaine HCl isn’t well documented, but I find that some clients do find hydrochloric acid really helpful for underactive thyroid issues.
