I am taking orally Life Extension brand Mega Benfotiamine (B1) 250mg 2x a day plus R Alpha Lipoic Acid 100mg 2x a day and B12 300 mcg .
With these Vitamins and my DBS, I feel "normal". I am trying to reverse or slow down the natural degeneration of PDby regenerating my nervous system. My family has noticed a remarkable improvement.
There is a product out there that combines all called nerve renew.
