Numerous clinical trials investigate the therapeutic and nutritional applications of (±)-α-tocopherol across conditions including type 2 diabetes mellitus, cardiovascular diseases, morbid obesity, micronutrient deficiencies, ischemia-reperfusion injury, and breast neoplasms. Ranging from Phase 1 through Phase 4 alongside non-interventional designs, these studies are sponsored by academic medical centers, government institutes, and global health foundations. Currently, recruitment statuses span from not yet recruiting and actively recruiting to completed or terminated.
