Even the best eating habits—fresh, whole foods with a lot of fruits and vegetables and high quality proteins—can sometimes fall short of the optimum levels of the nutrients your thyroid needs. It’s a good idea for you to take a multi-vitamin that contains minerals, too.
Below you’ll find what vitamins and minerals are most important for you and what doses you should look for in your supplements. Some minerals are important for thyroid health, but can interfere with how well your thyroid medication absorbs into your system. Plan to take your vitamins and thyroid medication four hours apart from each other to get the maximum benefits from both.
You can also give your thyroid an extra boost with some special herbal supplements.
Let’s look at how you can be sure your thyroid is getting all the nutrients it needs. When you choose vitamins, antioxidants should be at the top of your list. Antioxidants help to support the thyroid by reducing the free radicals in your system. Free radicals are a by-product of energy production, but they damage other cells, producing more free radicals in the process. When you reduce the free radicals in your body, you take pressure off your immune system, which makes it less likely to attack your thyroid.
Vitamin A is an important antioxidant. There is also a relationship between Vitamin A levels and thyroid disease. Studies show that patients with hypothyroidism have low levels of Vitamin A. This does not necessarily mean that Vitamin A deficiency contributes to low thyroid, but it does mean that when you have low thyroid you tend to need more Vitamin A. 16 If you have low thyroid, take between 10,000 and 20,000 IU of Vitamin A every day. This amount is usually available in your standard multivitamin. (Doses higher than 25,000 IU daily become toxic, so don’t take more than this amount.)
Vitamin C and Vitamin E are two other powerful antioxidants. Animal studies show that Vitamin C and Vitamin E improved thyroid function in mice with hypothyroidism. Inflammation of the thyroid gland, T3 and T4 levels, and cholesterol levels all improved from Vitamin C and E supplementation. 17 To support your thyroid and take full advantage of Vitamin C’s antioxidant effects, take 1000mg of Vitamin C each day. You won’t usually find a multi-vitamin with this amount, so look for a separate Vitamin C supplement. To get the most from your Vitamin E supplement, look for one that contains mixed tocopherols. (Most contain only alpha-tocopherols.) Take 400 IU of Vitamin E every day.
A Vitamin B complex is also important to your optimum health. This supplement contains a mixture of B-vitamins, which are important to your energy levels, mental health, and cellular integrity. Try a B-Complex vitamin that provides 50 mg of B vitamins.
