Most probably it’s not. You have to remember that a lot of companies are to some extent hiding behind claims of patented manufacturing processes. They are not actually lying, they have the patents on how to make it. It is rather easy to get a patent on manufacturing glucan.
Because at one step if you change the temperature, you immediately have a new process and you get a patent for it. It still doesn’t say the glucan is better and very few companies have patents on glucans showing that this particular glucan that they make is better in activity than the other glucans. So you can say whatever you want, the internet will accept a lot of things, a lot of statements. But if you cannot back it up with good science, it’s just your private statement.
