Guest guest Posted January 25, 2012 Report Share Posted January 25, 2012 Hi , People with hypoT may have low levels of Vitamin D due to poor absorption of Vitamin D from the intestine or the body may not activate the Vitamin D properly. Vitamin D and thyroid hormones bind to similar receptors called steroid hormone receptors. A different gene in the Vitamin D receptor has shown to predispose people to autoimmune thyroid disease both Graves' and Hashimoto's thyroiditis. Proper Vitamin D levels are essential for good health especially if you have thyroid problems. Screening for Vitamin D deficiency is recommended for all thyroid patients. http://www.goodhormonehealth.com/VitaminD.pdf http://www.ncbi.nlm.nih.gov/pubmed/21751884 http://www.ncbi.nlm.nih.gov/pubmed/3024434 http://www.ncbi.nlm.nih.gov/pubmed/20016683 The research is clear that 35 ng/mL is the minimum level of vitamin d for optimum function for healthy people. But people with autoimmune thyroid conditions aren't healthy. We often have GI disorders, inflammation, stress, excess weight, VDR polymorphisms (Studies have shown that a significant number of patients with autoimmune Hashis have VDR polymorphisms.) and other factors that impair the production, absorption and utilization of vitamin D. This suggests that the minimum 25 (OH) D level for us with AITD is significantly higher than for healthy people. My doctor wants my level at least 50, other experts recommend 60. Making treatment more difficult is the fact that fat-soluble vitamins A, D & K2 work synergistically together in the body. If vitamin A, K2 or both together, are also deficient and we only supplement vitamin d, this can lead to vitamin d toxicity. Also, vitamin d, calcium, phosphorus and magnesium need to be kept in balance -they work synergistically together in the body- as well to prevent bone, heart and kidney problems etc. My doctor tests for all of these together. Perhaps not considering all of this is why some patients feel much worse. But, actually, I have done a LOT of research on vitamin d and I have only come across a few people who felt worse leading me to wonder if you could have misunderstood. The people who felt worse had doctors that ignored the vitamin d/calcium connection and the vitamins A/D connection and so on. Thus this caused these patients to get too much vitamin d relative to other vitamins and minerals which, indeed, can cause toxicity. Some patients also experience side effects from certain brands, too; probably inferior additives and/or fillers. I experienced this myself with DHEA and I have finally found a DHEA supplement that I tolerate. As for feeling worse on generic T4, you could talk to your doctor about trying a different drug. Also, other substances need to optimal in the body for your T med to get into the cells and work efficiently such as vitamins B12, D and iron. Some people also have found that eating gluten-free helps the meds to work much better. Eating lots of refined foods that contain soy will also inhibit T meds. Good luck and I hope this is helpful, ~Bj > > I read about the vitamin d somewhere online in all of my searching for answers. Try searching for vitamin d and thyroid and i'm sure you will find things on both sides, helping and making worse. I considered Levoxyl, it's what my mom takes for her thyroidectomy and she does ok, but it seems like it might just be more of the same crap.I am trying to get in to a doctor in the morning that will prescribe naturethroid. After 1 week switching back to levothyroxine from synthroid I am feeling worse than ever. I had a few slightly better days last week that had me hopeful, but I should have known better. I am willing to try anything at this point, but I think these meds have to be part of the problem. Even if it was going to take time, it has been since the first week of november that I upped to 50 mcg, and 4 1/2 weeks since the 75 mcg switch. I should be getting slighty better and not worse, right? I literally can't live like this anymore. > Quote Link to comment Share on other sites More sharing options...
