Mr Nemo,you are right,do believe it is exported,we buy it from the people who harvest it,by the sack full,dry it and grind it and fed it to the livestock,has to be dried and mix it in their food,so far in the long run cheaper than store bought vitamins at least in our area,maybe not so in other areas,maybe it depends on where you live,so far it is working for us,I look at it this way,if it is good enough for humans must be good for livestock,maybe in the cities it would cost way too much. Have a nice day
