Hi, can anybody tell me if its ok to use cyanocobalamin? I have been prescribed hydroxocobalamin by my doctor which is administered every three months. My levels before my due date are usually around 200 which, from what I can glean from the posts, is still low. I recently bought some cyanocobalamin whilst on holiday but would not use until I was sure it was ok. I will take up the matter of low readings with my GP after my next test but low or not his reaction will be predictable.
