Celiac disease causes malabsorption of nutrients. As the video states, get these nutrient levels tested when you are diagnosed with celiac disease: vitamins A, D, E, K, folic acid, B12, and minerals iron, calcium, and phosphorus.
If your doctor never tested you, ask him to test you now. If you don’t have a doctor, or if you do, we recommend Spectracell Laboratories. Spectracell tests the nutrient levels inside your cells, not just those that are in your blood. This gives you an accurate result. (We are not affiliated with Spectracell.)
