Your body makes its own vitamin D and you also get it from dairy sources and supplementation. Vitamin D stimulates your bones to absorb calcium and also helps control your blood pressure. Synthroid is a synthetic form of the thyroid hormone prescribed for a condition known as hypothyroidism. Individuals with hypothyroidism may also exhibit lower than normal vitamin D levels, according to Theodore C. Friedman, M.D., Ph. D., author of “Vitamin D Deficiency and Thyroid Disease.” Current literature shows no adverse interactions between synthroid and vitamin D; however, because you are taking a prescription medication, take precautions when taking other drugs, supplements or vitamins. Consult your endocrinologist before starting your vitamin D regimen. Your endocrinologist can advise you of any precautions you should take regarding combining the vitamin D with your synthroid. Take your synthroid per your endocrinologist’s instructions. Your doctor may prescribe one daily dose or multiple doses spread throughout the day.
Take at least 1,000 IU of vitamin D daily, unless your physician directs otherwise. The maximum safe dosage, or tolerable upper intake level, is 4,000 IU. Work with your doctor to monitor your thyroid function and serum vitamin D levels. Your doctor may make adjustments to your synthroid or vitamin D dosage, if necessary.

Marge served as an admin in the Yahoo Natural Thyroid Hormones group for many years. One of the many downsides of being hypothyroid is the inability to absorb and/or metabolize a variety of vitamins and minerals, mostly due to low stomach acid. And unfortunately, many Vit D challenged patients think that all they have to do is sit in the sun and they will create enough Vitamin D. Not so for many hypothyroid patients! I was fortunate to have a decent doctor who tested my Vitamin D level when knowledge about vitamin D deficiency was in its infancy.
My level was 19 with a normal range of 30 – 100 ng/ml and he put me on high doses of Vitamin D3. Imagine my surprise when six months later, I didn’t need my daily asthma inhaler and I didn’t have a cold all year! Today, there are mountains of research into a myriad of issues that can be affected by Vitamin D. There is also a forward-thinking Vitamin D Council that will keep you apprised of current findings. In the Council’s December 21, 2013, newsletter, it reported about a study done in South Korea which found a link between vitamin D deficiency and autoimmune thyroid disease (AITD). The researchers found that “people who were deficient in vitamin D were much more likely to have TPO-Ab positive tests.” TPO-Ab is a marker for autoimmune thyroid disease and measures the level of antibodies specific to fighting thyroid-related cells. The Council newsletter went on to say, “The researchers calculated that those who were severely deficient in vitamin D had nearly twice as high the risk of a positive TPO-Ab test compared to those who were sufficient.”
So, does that mean vitamin D deficiency leads to autoimmune disease or that those with autoimmune disease are more likely to be deficient in Vitamin D?? Unfortunately, the researchers haven’t figured that one out yet and/or only offer opinion. The one thing researchers do know is “thyroid treatment isn’t optimal — and may not work — if you do not have adequate vitamin D for the crucial final metabolic step, which takes place at the site where thyroid hormone actually works. This happens inside the nucleus of the cell. Vitamin D needs to be present at sufficient levels in the cell in order for the thyroid hormone to actually affect that cell. That is why vitamin D is so crucial.” 1) The 25-hydroxy (25OHD) vitamin D blood test. The 25-hydroxy represents your body’s primary circulating form of vitamin D and the precursor to the below. 2) 1,25-dihydroxy vitamin D blood test, which is the active form. This is the test which recommendations of where you want to fall are based on.
