@looktothegut: Can't tolerate any supplements with MCAS? I reacted to every single one I tried. I was careful. I started slow. There was still one thing I hadn't tried. Send this to someone with MCAS who reacts to everything. My Mast Cell Support Library (25+ mast cell stabilizers, research, dosing, timing) is in my bio. If you have a severe reaction, stop and get medical help. This is not medical advice. #MCAS #mastcellactivationsyndrome #MCASsupplements #histamineintolerance #chronicillness
