I have loose dry skin and I recently found out I am deficient in Copper, B2, CoQ10 and Oleaic Acid in addition to already diagnosed Vitamin D deficiency. My hair has been falling out and I started taking the additional supplements for my deficiencies along with Biotin which is great for skin and hair. You may have some vitamin deficiencies due to malabsorption. My doctors would not order very many vitamin tests, they would only order what is considered common for most Celiacs. I had to go to a Nutrition Preventative Medicine doctor who ordered a slew of tests for me.
I was diagnosed last November and my tongue has been numb down the center for over 2 years and the Doctors cannot give me a reason. My vitamin B-12 is high on bloodwork. Since going gluten free it alternates between being numb and sore. It gets sore when I increase my liquid vitamins and/or sublingual B-12. Could I still be deficient?
