Could Vinegar Be the Next Big Thing in Treating Depression?
A recent study suggests that a daily dose of vinegar may help alleviate symptoms of depression, hinting at a potential new treatment avenue that could include a sour twist.
Researchers from Arizona State University examined the impact of regular vinegar consumption on depression, as well as metabolic activity—the processes that convert food into energy. They discovered a significant eighty-six percent increase in levels of nicotinamide (a form of vitamin B3) among participants who consumed liquid vinegar daily. This nutrient has been previously associated with anti-inflammatory effects.
“This data supports that daily vinegar ingestion over four weeks can improve self-reported depression symptoms in generally healthy adults, and alterations in [vitamin B3] metabolism may contribute to this improvement,” noted Arizona State University dietitian Haley Barrong and her colleagues in their published findings.
The trial involved twenty-eight overweight but otherwise healthy adults, divided into two groups: one group consumed two tablespoons of red wine vinegar twice daily, while the other took a pill containing a minimal amount of vinegar.
During the four-week experiment, participants completed two mental health surveys: the Center for Epidemiological Studies Depression (CES-D) questionnaire and the Patient Health Questionnaire (PHQ-9). While no significant differences were found between the groups on the CES-D, the group with higher vinegar intake saw a forty-two percent reduction in depressive symptoms on the PHQ-9, compared to an eighteen percent drop in the control group.
Despite the promising results, there are limitations: the sample size was small, participants had mild depression, and the improvements in PHQ-9 scores were not significant in a secondary analysis adjusted for baseline survey scores. Nevertheless, Barrong and her team believe the findings merit further investigation.
“Depressive disorders are the most common mental health conditions worldwide,” the researchers wrote. “Antidepressant medications often come with serious side effects, and their efficacy varies widely. Thus, simple, effective adjunct therapies are needed.”
The study adds to the growing body of research on depression, highlighting the need for a broader range of treatment options due to the condition’s variability among individuals.
The researchers concluded, “Future studies on vinegar’s effects in clinically depressed or at-risk populations, and those on antidepressant medications, are warranted. A focus on mechanisms and larger patient samples will strengthen the evidence for vinegar’s role in health promotion.”
