I started taking vit d, k2, b vits, iron and vit c. Ive been taking these vits for a while now and now feel im ready to start taking some more can you please advise me of which other vits i should be taking and which does please. Im on 150mg Leovothyroxine and have now started taking 5mg of T3 per day, i still am feeling tired and dull headaches with not much energy. In the past i have had some amazing advice. I have not had a recent blood test that i can refer to sorry. I do have Pernicious anemia aswell which i have 3 monthly injections for. Any advice is very much appreciated.
