The main supplements recommended for celiac disease are micronutrients, since damage to the small intestinal reduces their absorption. Deficiencies in vitamin B6, vitamin B12, iron, folic acid, vitamin D, copper, , and magnesium are common in people with celiac disease.[1] Gluten-free foods also tend to provide lower levels of magnesium, possibly warranting supplementation if insufficient levels are obtained through the diet after small intestinal damage has healed.[2] Probiotics have also been studied, since celiac disease is associated with changes in the gut microbiome.[3] Omega-3 fatty acid supplements have additionally been researched for their ability to reduce inflammation in celiac disease.[4]
