Leiber’s brewer’s yeast product was awarded by FERMA, an international trade fair and platform for producers and breeders of livestock, pork and poultry in Poland. A commission consisting of members of the Polish Chamber of Agriculture, scientists and a representative of the fair organization, awarded medals to two of Leiber brewer's yeast products.

Biolex® MB40 was awarded with a “gold medal”. The product, that as aquaculture applications, consists of the cell walls of genuine brewer's yeast (Saccharomyces cerevisiae), which are obtained during the production of soluble brewer's yeast extracts. Its high levels of beta-glucans and mannan-oligosaccharides actively support and relieve the immune system, and bind and inactivate pathogens and toxins in the gut.
