Any idea for someone with MCAS? I do a great deal for it through diet, lifestyle, supplements, pre abd histamine reducing probiotics, and meds, but I can’t tolerate even a little bit of caffeinated tea or coffee. The caffeine just sets my mast cells off like crazy. Weirdly most people with MCAS can’t drink beer, but as long as I stick to dark beers like stouts I don’t have a problem. And yes, very much in moderation, and along with water.
