Quercetin, a flavonoid found in many fruits and vegetables, has been investigated for its potential neuroprotective and anti-inflammatory properties, which are relevant to diseases like Multiple Sclerosis (MS). While there is some scientific interest in quercetin as a supportive treatment, the evidence remains preliminary. Most of the current research is limited to cell culture and animal models. These studies suggest that quercetin can modulate immune responses, reduce pro-inflammatory cytokines, and protect nerve cells from oxidative stress, all of which are mechanisms implicated in MS pathology. For example, some mouse models of MS (such as experimental autoimmune encephalomyelitis) have shown reduced disease severity after quercetin administration.

However, high-quality human studies are lacking. There have been no large, well-controlled clinical trials demonstrating quercetin’s effectiveness in treating or managing MS in people. Its use in MS is not grounded in traditional medicine, but rather in modern laboratory research. Some dietary supplement regimens for MS include quercetin based on these theoretical benefits, but major medical organizations do not currently endorse it for MS management. Thus, while there is a scientific rationale for further research, clinical evidence is insufficient to recommend quercetin for MS at this time.
