GAD1 Mutation and Slow Comt / Slow MAOA

Hi everyone

I have GAD1 gene mutation (TT) - this gene is responsible for conversion of glutamate to GABA. How can I support that conversion (taking into account that I have slow COMT and slow MAOA as well)? I found on the web that B6 is the co-factor of the whole conversion process. Vitamin B1 and Riboflavin too are mentioned.

What might be other supplements necessary for that particular enzyme?
