Collaceina is a unique and effective food supplement with comprehensive effect on the immune system. It includes two kinds of capsules. The first one contains nature-derived substances with high immunising properties, such as lactoferrin, lysozyme and colostrum. The second one consists of nine selected live bacteria culture strains, whose task is to maintain the balance of bacterial microflora in our digestive tract, and prebiotic food for these bacteria, i.e. fructooligosaccharides.
