Beta Glucan for Strep Throat

I get strep throat literally every 4 months because I never had my tonsils pulled as a kid. I've tried everything to prevent it from coming but nothing has ever worked until it comes down to getting penicillin form the doctor. I herd of Beta Glucan from a lady at a health food store and she told me to take one every morning so it stays in your system. I havent had strep throat in 2 years until I moved to Australia and ran out. I now appreciate how well it really works and I can't wait to get it back in my system.
