Synopsis

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

The use of vitamins, particularly B vitamins (such as B12, B6, and B1), to support or treat Bell's Palsy is primarily justified by historical and traditional medical practices rather than strong scientific evidence. Traditionally, B vitamins have been thought to support nerve health and regeneration, and thus have been included as adjuncts in the management of peripheral neuropathies, including Bell's Palsy. The rationale is that these vitamins may help repair damaged facial nerves by supporting myelin sheath integrity and overall neuronal function. Several small, older studies and anecdotal reports have suggested possible benefits, but high-quality clinical trials are lacking or have shown inconsistent results. Guidelines from major neurological associations generally do not recommend vitamins as a primary treatment for Bell's Palsy, focusing instead on corticosteroids as the mainstay of therapy. There is some limited evidence that combining corticosteroids with B vitamins may be beneficial, but this is not well established. In summary, while the use of vitamins in Bell's Palsy persists due to tradition and theoretical benefit, robust scientific validation is lacking, and the evidence supporting their use is relatively weak.
