Lacto-Levur is a food supplement for live lactobacilli (Lactobacillus bulgaricus, L. sporogens, L. acidophilus, Bifidobacterium bifidum, Steptococcus thermophilus) and vitamins (niacin, pantothenic acid, Vitamin B6, Vitamin B2, Vitamin B1, Vitamin B12). The probiotic lactobacilli present in Lacto-levur are the main components of man's bacterial intestinal flora and are useful in situations of alteration of the intestinal flora. It is indicated for the rebalancing and rapid recovery of the intestinal bacterial flora. Rebalancing the flora is advised in the event of qualitative or quantitative changes in bowel functions. Therapy with antibiotics, eating disorders, low fiber diets, climatic and hygienic changes, stress and flu are the main causes of these changes, the symptoms of which are disorders of the intestinal tract, bloating, abdominal tension, difficulties in digestion and skin impurities. The vitamin B group acts as an essential biological catalyst in the formation of enzymes that play an essential role in the correct performance and cell growth. Under normal conditions, vitamins are synthesized by the intestinal flora, so in cases of alteration of the bacterial flora, they will have to be integrated. Sodium phosphate protects bacterial strains from gastric bacteria due to its high buffering power. Hydroxypropylmethylcellulose, when in contact with gastric juices, swells and becomes spongy, protecting lactobacilli from the action of hydrochloric acid in the stomach and allowing them to pass the gastric barrier, so that they reach the intestine intact
