So after reading llm's post about the antibiotic that can remove excess glutamate, I am even more confused about the whole glutamate/GABA thing. I had been thinking about GABA supplements for DS because GABA is calming and his PANDAS symptoms are fairly large/prolonged motor tics and vocal tics. But now I have read that GABA and glutamate and glutamine all get converted to one another, so giving a GABA supplement wouldn't do much if it just gets converted into glutamate anyway??
Is it better to try l-theanine instead? I have read that it gets converted into calming substances such as GABA.
I'm interested to hear if anyone has tried these, with success or not. Thanks!
