The green-lipped mussel, native to New Zealand, are known to many as a dietary supplement. In recent years, however, it has made its way into fish food because of the incredible attractiveness of carp. The reason is valuable amino acids, vitamins and minerals. Our GLM is obtained from pure, lyophilized and partially defatted mussel meat. A product that is impossible to overdose and for him it is worth the more the better. You will be amazed only by the smell!
