For example , in this study 2 g daily were given for 6 weeks with no ill effectGlycine transporter I inhibitor , NMethylglycine sarcosine , added to antipsychotics for the treatment of schizophreniaI ' d say if you were roughly within that dose regimen you have nothing to worry about both the study itself and the fact that it passed ethics review and was run strongly suggest that the dose is safe . Most likely whatever you experienced was either an acute effect of the drug , a placebo effect , a coincidence , or some combination of those three . Not likely to be due to any form of neurotoxicity .
