Have Hashimoto's - antibodies 648 (range <6), and fibromyalgia. Vitamin B level 235 (range 211-900). Folate 9.9 (range2.4-20). Treatment with T3 and T4 has helped but still have problems with tremors, palpitations , balance issues and loss of sense of touch. Have ordered a range of supplements to support metabolism but in particular have started on Jarrows methylcolbalamin 1000mcg twice a day. Is this enough and how soon might I feel some effect?
