If you suffer from a mast cell activation disorder (MCAD) such as mastocytosis or mast cell activation syndrome (MCAS) you may benefit greatly by taking quercetin, even over cromolyn. I recently found this bioflavinoid in my search to improve my own struggle with an as yet diagnosed mast cell condition and have been very impressed with the initial results. In this post, I will discuss the properties quercetin possesses, what’s been found in laboratory testing regarding the supplement, my own experiences with the supplement and whether it might be right for you.
