Hi Joviony,
Welcome to the site. I did some googling for you and came up with these links for you.
https://www.ncbi.nlm.nih.gov/pubmed/17895634
https://www.ncbi.nlm.nih.gov/pubmed/19571787
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2704234/
The last link seems to contain quite a bit of info there. Have you tried to search the forum here for more info? If not, you can go to the search forum function at the top of the page and that will throw up any posts here on the site about Beta Glucans if there are any.
Hope some of that is useful to you and my best wishes to you as well.
Gavin
