Hi, I tested for urinary neurotransmitters lately and all came out clearly below range. serotonin, glutamate, gaba, adrenaline, nor adrenaline and dopamine. The Dr. himself had no clue Why and said he had rarely ever seen such a result before. I think this is an important part as to why I am feeling so much like crap. I read alot and the only intervention seems to be neurotransmitter precursors like phenylalanine, tyrosine, Tryptophan, theanine and cofactors like b6. The success rate is questionable at best. Does anyone have any idea as to why this is,? Can neurological damage lead to such a result and is there any promising treatment for this that I might not have heard of? And did anyone also test for neurotransmitter levels?
