The Key Determinants in Beta Glucan Effectiveness
Neither the volume nor weight of beta glucan determines effectiveness or optimum dosage, but rather the key determinant is the degree of activation of the immune response by any given glucan in a specific amount, determined by an acceptable scientific method. In other words, more is not always better - judge by the extent to which the amount of beta glucan in a product enhances the immune response and not by the quantity of any given beta glucan in a capsule.
High milligram dosages and high percentages of beta glucan in a capsule are not determinants of immune response or ingredient purity and cell activation. The true determinants of immune response activation and effectiveness are beta glucan source, processing (including avoidance of reaggregation during digestion), sizing and uniformity of beta glucan particles ingested.
