Rating (out of 5): 2

Vitamin E, comprising mixed tocopherols and tocotrienols, is used as an adjunctive therapy in Inflammatory Bowel Disorders (IBD) such as Crohn's disease and ulcerative colitis. The rationale for its use is primarily based on its antioxidant and anti-inflammatory properties. Oxidative stress is implicated in the pathogenesis of IBD, with increased levels of reactive oxygen species (ROS) contributing to mucosal injury and inflammation. Vitamin E, as a lipid-soluble antioxidant, can scavenge free radicals and potentially reduce oxidative damage in intestinal tissues.

Several animal studies indicate that both tocopherols and tocotrienols can attenuate colonic inflammation, reduce markers of oxidative stress, and improve histological outcomes. Some small pilot clinical studies have noted lower serum vitamin E levels in IBD patients, and limited interventional trials have suggested symptom improvement or reduced disease activity after supplementation. However, robust, large-scale randomized controlled trials in humans are lacking, and the benefit seen in experimental models does not always translate to clinical efficacy.

Current evidence for Vitamin E's use in IBD is suggestive but limited, and it is not considered a primary or standalone therapy. Its use is sometimes justified as a supportive measure, especially in patients with documented deficiencies or increased oxidative stress, but clinical guidelines do not universally recommend routine supplementation. Thus, the scientific evidence is preliminary, meriting a rating of 2 out of 5.
