Hi, Dreambirdie.
I don't know for sure what would help you. What I can do is suggest some possibilities, based on biochemical theory. One is that there is a reaction that converts glutamate to GABA, and it requires P5P, the activated form of vitamin B6. B2 is needed to activate it. So perhaps supplementing with B-complex vitamins could help.
Another possibility might be liposomal glutathione, in the hope that some of it would make it into the astrocytes, and that they would then be able to pump glutamate out of the synapses faster, because there would be less oxidative stress in their mitochondria, and they could thus make more ATP to drive the import of glutamate and its conversion to glutamine, both of which require ATP.
Another possibility might be to take some of the supplements Amy Yasko has listed to help with excitotoxicity. These include GABA, theanine, progesterone cream. magnesium, taurine, Valerian root, and some others (her book "Autism, Pathways to Recovery" or her forum at
www.ch3nutrigenomics.com give more information about these supplements). She also emphasizes minimizing foods that contain glutamate or aspartate, especially MSG or aspartame (Nutrasweet).
Another possibility might be to take activated charcoal or other binders to tie up the toxins and carry them out in the stools, so that once they have been delivered to the gut via the bile they will not be reabsorbed from the gut and enter the enterohepatic recirculation.
Another possibility might be to drink lemon juice regularly (being careful to use a drinking straw and to flush the teeth with water immediately afterward, to protect the tooth enamel). This will paradoxically alkalinize the urine, and that will cause toxins that are chemically in the form of weak acids to tend to be excreted in the urine rather than being reabsorbed by the kidneys and returned to the blood.
Those are the things I'm aware of.
Best regards,
Rich
