Hello I have gone through your query and understood your concern. Nutrilite boi c and perselenium E are dietary supplements that respectively helps replenish vitamin C and E throughout the day. If your actual symptoms( sleepless, pain in my body and nose bleeding)appear after your start the supplements, i deduct that these vitamin supplements are the cause of your actual problems. In my opinion,it is necessary to stop for a couple of days BioC and Parselenium E to see if they are related to your symptoms or not. At the other side,for your hypothyroidism i suggest to start the thyroid hormone replacement therapy or levothyroxine to stabilise your TSH test and to feel better. Hope this is helpful. Let me know if i can assist you further. Take care.
