How effective is the Advanced Hearing Formula supported by Dr. Frank Shallenberger and marketed through Advanced Bionutritionals in reversing and preventing hearing loss?

This can work as advertised. Many causes of hearing loss are poorly understood and this is really true across the board. The ingredients in this formulation, in part, have well-established scientific track records in showing clinical efficacy in their own right, and that is his basis for supporting this product. It will have a significant benefit for many and as you saw intuitively, the benefits go far beyond support of hearing. There are many neurological functions that will be enhanced by taking this formula. Your perception of this as a good general tonic is well deserved.
