Depression is a debilitating illness associated with diminished quality of life and significant personal and societal costs. Depression is twice as common in those with type 2 diabetes compared to the general population. Antidepressants are commonly prescribed as treatment for depression; however, they may not be the optimal treatment for people with type 2 diabetes. Creatine has been shown to decrease symptoms of depression in many types of individuals when used over the course of 8 weeks or more. The purpose of this study is to investigate whether creatine can decrease symptoms of depression in individuals with type 2 diabetes when taken daily for 12 weeks. This study also investigates how creatine impacts brain chemistry as creatine decreases depressive symptoms.
