Reply To: I am 28 years old and 20 weeks pregnant. At 15 weeks I had my vit D tested. It came back at a 10.7 which I know is severely low. My general Dr. and OB have agreed to only put me on 1000-2000mg of Vit D daily. However, my chiropractor and I strongly agree that I need more. What is a safe range to take while pregnant?
