Surprized no one has commented here. I suggest you do a search in these Forums
and I think you will find lots of information regarding the subject of micronized, etc.
Yes, there is a lot of remarks about micronized kava in various topics on this forum. Not so positive, since micronized kava particles are bigger than filtered particles (typical mesh size 80-100) and people complain (I belong to them) that micronized kava is indigest if used as such.
