Pyroluria Pyroluria is a genetically determined chemical imbalance involving an abnormality in hemoglobin synthesis. Hemoglobin is the protein that holds iron in the red blood cell. Individuals with this disorder produce too much of a byproduct of hemoglobin synthesis called "kryptopyrrole" (KP) or "hemepyrrole." Kryptopyrrole has no known function in the body, and is excreted in urine. http://drkaslow.com/html/pyroluria.html
Pyroluria Pyroluria is a familial disorder which occurs with stress, where an above-average amount of a substance consisting of "kryptopyrroles" circulate in the body. The substance is harmless in itself, but high levels of these pyrrolles systemically bind with B6 and zinc, preventing the use of these essential nutrients in the brain and body. The result is a myriad of symptoms, including severe inner tension, ongoing anxiety, poor stress control, fearfulness, and sometimes episodic anger. http://www.diagnose-me.com/cond/C372380.html
