Thyroid Disorder and How Much Vitamin D Do You Need?



If you suffer from a thyroid disorder, you should know that it may be difficult for your body to absorb vitamins and minerals like it should. Research has found that those suffering from vitamin D deficiency were much more likely to show the marker for autoimmune thyroid disease when tested. In fact, those patients that were severely vitamin D deficient had nearly twice the risk.

This doesn’t definitely mean that if you have a vitamin D deficiency that you will get autoimmune thyroid disease. Vitamin D is, however, crucial in the body’s metabolic process which is regulated by the thyroid. Vitamin D HAS to be present in adequate levels in the nucleus of the cell for the final step in the process to be completed.

Vitamin D is only available in small amounts in the foods we eat, so it has to either come from supplementation, the sun, or ideally a combination of both.

For thyroid patients, the largest part is generally supplementation. For the average person, the daily recommended optimal level is constantly being debated. It ranges from 50ng/ml to 80ng/ml. This is used to determine the dosage, so obviously that is up for debate as well. That ranges from 400 IU/day to 5,000 IU/day. If you look at the Grassroots Health chart, you’ll see that the ideal dose is thought to be 35 IU/lb of body weight.

The amount you need to take can be affected by body fat, inflammation in the gut, high levels of cortisol, aging, auto-immune issues, hindered fat absorption, drugs that reduce absorption, and genetic defects. Testing regularly is definitely recommended, but most thyroid patients have found their level doesn’t rise at all unless they are taking at least 5,000 IU/day due to problems with absorption caused by thyroid disorders.

Vitamin D3 is recommended over D2 by the Vitamin D Council, because it is the type naturally produced by your body. Vitamin D is easy to take, easily absorbed, and can be taken any time of day with or without food. It is fat soluble, and your body has difficulty getting rid of it if you take too much, so take the recommended amount only. The highest recommended dose is 10,000 IU/day. If you experience vomiting, nausea, weakness, nervousness, reduced appetite, thirst, or excessive urination, you should consult your physician to check for toxicity.

If you suffer from hypothyroidism, the symptoms can mask vitamin D deficiency symptoms. You may be experiencing fatigue, aches, and pain from your thyroid disorder and not realize you have a vitamin D deficiency. Vitamin D is crucial for bone health and need to be optimal along with cortisol and iron for the thyroid receptors to properly respond and for your thyroid medications to work for you.

The bottom line is that no two patients are alike. Generally speaking, doctors like to prescribe at least 10,000 IU/day at first to get your levels up to where they need to be. Once the desired level is reached, the level can be decreased until you find the dosage that keeps it where you want it to be.

Many thyroid patients think they can get enough vitamin D from multivitamins. The regular multivitamin usually has about 400 IU for the daily dose. For most people that is nowhere near enough.

Talk to your physician. Have the proper testing to determine what your vitamin D level is and if you are vitamin D deficient. Let the doctor prescribe the dose they feel work for you and take it as prescribed. This should keep you going and help you to feel better in no time.
