The nutritional supplement contains Butaren®Amino calcium and sodium salt of butyric acid and L-Glutamine. Glutamine is the amino acid that is found in greatest quantities in skeletal muscles and which is ejected in large quantities during strenuous physical exercises. Excretion of glutamine by muscle tissue enhances the immune system. It also improves function of the gastrointestinal tract, increases the production of glycogen, and in addition, enhances the separation of the ammonia by the kidneys, increases the activity of brain activity. Butyric acid has beneficial effects on epithelial (surface) cells of the colon. It is one of the few substances that are directly used by the intestinal cells without passing processing in the liver. The beneficial actions of butyric acid and L-Glutamine are potentiated by the unique combination of both substances in Butaren®Amino. On one hand the growth and quality of cells of the colon are stimulated, and on the other hand, the operation of muscle tissue and metabolism in general are supported. This leads to improvement of activity of the colon, increase of body weight, detoxification and strengthening the immune system, normalization of homeostasis. strengthening of the immune system and normalization of the homeostasis.
