Beta-glucanase breaks apart beta-glucans, the soluble fibers in grains, yeast, and some fungi. Cutting these fibers lowers the gummy texture they form in the gut, which helps digestion and lets you pull more nutrients from your food.
People take this enzyme with meals that are high in fiber or rich in beta-glucans. Swallow it alongside food so it can go to work on complex carbs while you eat.
Watch out if you also take beta-glucan supplements meant to wake up your immune system. This enzyme can cancel their effect. In some cases, you might notice mild stomach upset.
