Clinical Trial Summary

In this study, the investigators aim to assess if vitamin B12 treatment demonstrates a beneficial effect on voice performance. If so, they wish to examine the relationship between the vitamin B12 treatment and the study participant's general well-being.


Clinical Trial Description

Through the investigators' experience, they have observed that amongst singers and voice professionals, there is a common belief that there are voice benefits from cobalamin treatment. Consequently, some singers and voice professionals tend to ask for cobalamin injections in order to enhance their vocal performance. However, there are no previous reports that illustrate the effects of vitamin B12 deficiency or treatment on voice performance. ;
