IntroductionThere is a belief among vocalists that there are voice benefits from vitamin B12 treatment. Yet there are no previous reports regarding vitamin B12 effects on voice.ObjectivesTo assess the prevalence of vitamin B12 use among singers and their beliefs regarding vitamin B12 therapy.MethodsAnonymous online survey administered to singers, singing-teachers, speech-language pathologists, and laryngologists.ResultsA total of 192 participants completed the surveys; 128 singers (68 singing-teachers, 30 speech-language pathologists) and 64 laryngologists. Among singers, 12% have perceived voice benefits from vitamin B12 treatment taken for any reason. Four percent used vitamin B12 for voice benefits; all perceived voice benefits as a result. The leading voice benefits were improved stamina, reduced effort, confidence, and control. Nineteen percent of the singers would recommend vitamin B12 treatment to a friend; 15% of the singing-teachers would recommend it to a student. Among laryngologists, 33% been asked by a singer to prescribe vitamin B12 for voice benefits; 9% have prescribed it in the past. Yet only 3% would you recommend it to a patient.When asked "Do you believe vitamin B12 therapy improves vocal performance?" 31% of the singers responded "Yes," compared with none in the laryngologists. When asked "Do you think the singing community believes vitamin B12 therapy improves vocal performance?" 26% of the singers responded "Yes," compared with 53% of the laryngologists (P = 0.0002).ConclusionsThere is a discrepancy between the singers' and the laryngologists' beliefs regarding vocal benefits perceived by vitamin B12. Blinded randomized trials are required to verify or refute this belief.
