Hi Anne,

Marilyn here. I was just tested last month for Vit D 25 Hydroxy, and my results showed that my level was 24 (20-100)nl.
This is after being on a GF diet for just over 15 months, and taking 1200 - 1600 IU of D daily for + 12 months. In 01 last time the test was done it was 35 (eating gluten at that time). I wonder how much lower it might have been without me knowing it. It will be interesting to see what this year's Dexa results will be. Perhaps this explains why in spite of taking medication, calcium and extra D, and weight training that the bone density shows minimal improvement.
