I am 34 year old woman and I have been fighting low vit D for the last couple of years. A year ago, it was really low and I was put on 50,000 IU pill once a week for 6 months. I was retest and it was better but still not normal (up to 18.8). I was told to take 2,000 IU every day and test again in 6 months. I was just test and my vit d is now 15.0 so my doc is putting me back on 50,000 IU once a week for 6 months. That seems really high to me. Is that ok? Thank you so much!
