The preparation PROBIÓTICOS + OSTRA MUSHROOM with FORTE beta-glucans contains the stem of the mushroom including beta-glucans, probiotics (Lactobacillus acidophilus, Bifidobacterium bifidum, Bifidobacterium lactis) and the rose hip plant (Rosa Canina, Rosa Laevigata). By combining probiotics with oyster mushrooms, the rose hip fruit (Rosa canina, Rosa laevigata) and vitamin C, which contributes to the normal functioning of the immune system, we achieve an original and natural recipe. The oyster mushroom (Pleurotus ostreatus) is a fungus that contains a wide range of substances such as beta-glucans, fibre and other components.
