I am disappointed to learn that like too many "health supplements" they have added micro-cystalline cellulose , a nano-particle to which people may have a particular sensitivity, or documented, allergy, and which is an indigestible plant processed ingredient that is not meant to be blood bornes and dos not break down into a digestible sgfar but rather is blood borne and can be considered to be prospectively and cumulatively a blood barrier. NOT A GOOD THING . I take NOTHING with microcrytalline cellulose, I had bad reactions and they included brain fog. Considering that this naon-particle may in fact cross the blood brain barrier (there for a reason) i suggest you study this onw before takin
