I had my 3rd meeting with my neurologist in July. I informed him that I had started taking biotin and felt it was helping with the weakness my ankle. He said to continue with it if I felt it helped but to go off and read about MitoQ. I don’t know if anyone else is taking MitoQ but after reading about it I ordered some and have been oin it now foir 2 months. These are definitely having a positive effect on my energy levels and I have not experienced fatigue. It may be just a placebo effect but definitely worth a look.
