Product Overview


  • Dietary Supplement
  • Purified Beta-1,3/1,6-Glucan

Beta-glucan is a complex polysaccharide composed of glucose molecules extracted and purified from the cell wall of common baker's yeast, Saccharomyces cerevisiae. Beta-glucan is used to maintain or stimulate the effectiveness of the immune system. Animal and human cell culture studies have shown that beta-glucan can stimulate several aspects of immune function, such as phagocytosis and interleukin production. Source Natural's Beta Glucan uses a purification process that removes the mannoproteins and yeast residues that may reduce the effectiveness of beta-glucan.

Beta Glucan

Posted by specialgirl on Sep 02, 2015

This is the first Beta Glucan I ever tried and it did nothing for me. I only took one a day for a month. Maybe I needed two but I do not like to double up on vitamins. The good thing about this glucan capsulse is that I loved the size of the capsules. Not too big just the right size. I enjoyed taking these capsules but they did not help to build up my immune system. I will try them again in the future and take two instead of one. Source Natural is a good company.

Beta Glucan products have a high variability in efficacy. I order this for a friend of mine, who says the Source Naturals is the only one that works for him.
