Hi, I've been feeling pretty rubbish for about a year. Low mood, hair loss, cold, aches especially headaches, constipation, pounding heart, breathlessness. Had blood tests and told over phone that all results were normal. So I asked for a print out. My TSH is 2.4, B12 269, folate 3.3, ferritin 19, vitamin D is 50. Does underaction thyroid cause the low levels of other vitamins? If I treat myself with supplements would that help the thyroid levels? I don't know where to begin with supplements though and no help forthcoming from GP. Thank you. Pic of full blood test results attached.
