 [ Symptoms ] i have thyroid problem my hr and bp fluctuates often why [ Disease ] wow i took one look at your list and thought i hope she has a medication record and tells everyone all of the supplements she is taking it is very important that all of your health care providers know everything that you are taking including over the counter medications vitamins and supplements you are correct by taking your synthroid in the morning with nothing else    that is the most important medication all of these can cause nausea in general you also want to separate the calcium from the ferrous gluconate may i also ask why you are taking two multivitamin tablets twice a day you may be running the risk of toxicity because remember not all vitamins are water soluble some are stored in your fat cells i would not recommend taking such a high dose of something like that you may want to have your health care provider to run blood work to see what your levels are to make sure
