You might notice some vitamin d deficiency symptoms as you get your vitamin d back up -- that's not uncommon. A level of 10 is really low -- it will be good for your health to get it up. It might take a long time -- you can eventually take 8000-10,000 IU per day to help. Start slow to get used to it.
