Someone with celiac disease on strict gluten-free diet should absorb needed vitamins without the need for special supplements, unless there’s:

• Incomplete healing (persisting symptoms, clinical signs of malnutrition, an abnormal repeat biopsy); or
• Laboratory evidence of nutritional deficiencies (anemia, low bone mineral density, low cholesterol, low prealbumin, low iron, etc.).

We do, however, recommend a multivitamin to our adult patients since most gluten-free processed foods aren’t fortified. June, 2017
