This common vitamin could help fight one of the deadliest brain cancers

University of Calgary researchers are conducting a clinical trial to see if high doses of vitamin B3 (niacin) can improve outcomes for patients with glioblastoma. The study aims to determine if niacin can help counteract the tumor's ability to suppress the patient's immune system.
