Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Bell’s Palsy is an acute, usually temporary paralysis of the facial nerve, often attributed to viral inflammation. The use of Vitamin B6 (including its forms such as pyridoxamine and the more common pyridoxine) for Bell’s Palsy primarily stems from traditional practice rather than robust scientific evidence. Historically, B vitamins—especially B6 and B12—have been empirically used in various forms of neuropathy, including facial nerve palsies, based on the general role of B vitamins in nerve health and repair. Some clinicians, particularly in parts of Asia and Eastern Europe, have included B-complex supplementation in treatment regimens for Bell’s Palsy, often in combination with steroids and antiviral medications.

However, contemporary scientific validation for the efficacy of Vitamin B6 specifically in Bell’s Palsy is limited. There are a few small studies and case reports that mention B6 (often grouped with other B vitamins), but these lack the rigor and scale necessary for high-quality evidence. Systematic reviews and clinical guidelines, such as those from the American Academy of Neurology, do not endorse B6 supplementation as a standard treatment, citing insufficient evidence. Most clinical improvement in Bell’s Palsy is attributed to early corticosteroid therapy, with or without antivirals.

In summary, the use of Vitamin B6 for Bell's Palsy is justified more by traditional empirical use and the general nerve-supportive reputation of B vitamins than by solid scientific data. The evidence supporting its use is weak and not widely recognized in contemporary medical practice.
