My Vitamin D 25,Hydroxy came back at 6.7 ng/ml. Two years ago it 17, last year it was 10, and now it's 6.7 ng/ml. I work from home so I'm thinking that could be why, I don't get out all that much. Doctor wants me to take 50,000 IU every week, but I don't like supplements and am wondering if I can just eat food and forfeited juices/milk to get the levels up. I'm been oversleeping like 9-10 hours a day.. Could this level cause that?
