Lglutamine and FOS

Hi
I am taking Enteroguard for some time now,which is intestine conditioner with vitamines,l-glutamine and FOS.
I start to have short breath,heavy chest,feeling cold all over again and my question is,is it FOS feeding my candida,bacterial dysbiosis (staphylococcus)?
I will take a break from it for a week and see whst happens but if I have to stop for good do you know any l-glutamine product/brand that you can recomend ? Tweet
