The result of my amino acid test showed impaired detoxification, nitrogen insufficiency, and need for magnesium. Apparently im in the below normal level for metionine,leucine,isoleucine,taurine,cysteine,alanine,asparatate,glutamine,cystine,serine,citruline,phosphoethanolamine whether it's due to my bo, terrible eating habits or my serious digestive problems im not sure probably a combination. apparently a lot of these proteins can be low due to zinc insufficency, and 2 of them mentioned cystinuria. it was something im interested in getting tested for. Good luck to you all and i hope we find the answer to our search soon.
