Beta glucans can come from yeast, medicinal mushrooms and cereals, such as oats and barley.
Studies show that yeast beta glucan is superior for supporting and enhancing immune function.
Yeast cell walls contain 5 to 10 times the beta glucan content as compared to medicinal mushrooms, resulting in a product with more active ingredient.
