I am finding that I regularly get headaches, that can turn into migraines if not dealt with quickly, when I take vitamin supplements. This happened when I was pregnant and taking pregnacare and also since when I was advised to take a variety of vitamins to help with pcos. I did feel like they were helping me feel better in other ways but I couldn't cope with the headaches and have stopped them. Anyone else had this and have some advice? If I persevere taking them will I adjust and the headaches stop? Would timing/ type of supplement make a difference? Thanks
