Who knows?
"Didn't rate it tbh, it tasted ok but wouldn't dissolve in boiling water so unless you are literally licking the glass out then you're not even getting the full dose. Didn't see any improvement, I've now changed to a different type of the same product but this is my fourth purchase so that's it after this if I don't see results as its not exactly cheap. Maybe they spend too much time on the look of the jar instead of the actual product."
