Hypothyroidism Support Group
Hypothyroidism is the disease state caused by insufficient production of thyrohormone by the thyroid gland. There are several distinct causes for chronic hypothyroidism, the most common being Hashimoto's thyroiditis and hypothyroidism following radioiodine therapy for hyperthyroidism. Advanced hypothyroidism may cause severe complications, the most serious one of which is...

These are the alternative and mostly natural ways to get the vitamin D while skipping the dairy;
Top 10 Vitamin D Rich Foods
1) Sunlight-Promotes vitamin D synthesis from cholesterol in the skin.
2) Cod liver oil-1 tsp: 440 IU (over 100% DV)
3) Sardines-3 ounces: 164 IU (41% DV)
4) Salmon-3 ounces: 400 IU (100% DV)
5) Mackerel-3 ounces: 400 IU (100% DV)

In addition to the vitamin D shortage which a fair # of ppl not only in the N. hemisphere have, vitamin E is another. I take a Daily multivitamin which has 100% of the D & E in it in addition to a handful of other minerals. I formerly took a separate vitamin D supplement in addition to the daily multivitamin and was consuming roughly 350% of vitamin D which was more than I needed so cut out the extra vitamin D supplement so still getting 100% of daily recommended value.
We think we need dairy and who doesn't like a good slice of gluten free pizza with oodles of cheese on it. Well, a minute of tasting good, causes problems a day or two after so, eliminating dairy products is not a bad idea either especially if hypo.
Last comment on recommendation is to avoid SOY. I had a situation a few years ago when I did give up dairy and switched to processed soy which was the equivalent of making dracula walk around with garlic; on his neck, in his favorite cup of liquid, in his 'bed/cave', etc. However, research I've read about indicates that the interference of isoflavones with thyroid hormone production is a problem only when there is underlying iodine deficiency. So, if you are getting enough iodine through your diet, it's unlikely that eating soy will contribute to hypothyroidism.
Hope you've found some relief.
