Reply To: I tested at 33ng/ml and started taking 10,000 of D3. After 7 weeks I retested and I am at 60 ng/ml. I weight 135 pounds. What should my maintenance dose be? Also, I started this regime because I have inflammatory auto-immune condition, and also a chronic hamstring tendenosis for three years. I heard vitamin D can help those conditions. How long does it usually take to see if D will improve these conditions. Thanks.
