<<Disclaimer: Verify this information before applying it to your situation.>> This is very interesting to know. My daughter also has easy brusing on her arms and legs. Her doctor checked her glidian ( guten antibody panel ) and some other blood chemistry and told me that she does not have celiac disease or leukemia. But, after I gave her plenty of V8 juice, tomato has Vitamin K in it, her brusing stopped. But, for the passed few days, her bruises came back again, and I know she did not drink as much V8 ( used to be 3 bottles a day) as before, but she did take barley green drink. Her energy level is low. Then I read about parasites can also cause gluten intolerence. I would like to check into that soon. Mei-Tien
