About two years ago when I was seeing my doctor for depression/anxiety/headaches he wanted to check my vitamin D level, and to our surprise it was at 13! :O He started me out on 2,000 UI a day. Later on I was hospitalized and I explained to the new doctor my vitamin D condition, and he said 2,000 was way too low. Now I am taking 50,000 UI weekly. I had it checked a little over half a year ago and it was at 28.

My doctor at least wants me above 30. I am still taking the 50,000 UI. Slowly but surely I'm getting up there, and my depression hasn't been as bad (I'm fifteen - by the way)
