Beta glucans are a class of natural polysaccharides that have long been investigated for their immuno-modulating properties, ever since the substance responsible for the beneficial effects of Shiitake mushrooms and other beta glucan-containing foods was identified.
Leiber GmbH, Germany, offers a range of specialized yeast products. One of them is Yestimun®, an 85% pure beta glucan derived from Brewers’ yeast. Yestimun® is a valuable ingredient in that it is recognized by certain immune receptors in the digestive tract, triggering an immune modulating response. The effect on the immune system has been proven in own clinical trials which have been published recently.
