I have studied at least 50 maybe 80 different glucans from countries all around the world. I had glucan from my own country of course but several countries like South Korea, Taiwan, Russia, Croatia, Turkey, you basically name it. I try  to compare them together at some kind of “best level” and if it’s is possible I publish these comparative studies. There are at least two or three already published. So it’s available online at PubMed. It’s possible to find them. It’s out there.
