Zinc Carnosine Complex with PepZin GI by Doctor’s Best is a dietary supplement containing the complex of zinc and carnosine, helping to fight with the ailments of the digestive system.

Zinc Carnosine Complex with PepZin GI by Doctor’s Best contains in its composition the following ingredients:

Zinca microelement, essential for the proper functioning of the whole organism. It plays a range of important roles in metabolic and biochemical reactions. It takes part in the transformations of amino acids, carbohydrates and lipids, which is reflected in increased energy provision to each cell.

It activates and regulates the work of such organs as pancreas, thymus and prostate. It strengthens defense mechanisms of the immune system by the participation in the production of lymphocytes T. It protects from bacterial and viral infections, therefore zinc is recommended in the flu and cold periods. It is also incredibly helpful in the course of autoimmune diseases, such as psoriasis and rheumatoid arthritis. It mitigates the symptoms of dysfunctions of the digestive system, e.g. gut inflammation and it positively influences the state of skin, hair and nails.

L-carnosinea dipeptide composed of two amino acidsbeta-alanine and histidine. In the largest amounts it is located in muscles, heart and brain, i.e. where we observe the highest need for energy.

It is known for its strong antioxidant properties – it protects cells from the harmful influence of reactive oxygen forms, such as glycation, oxidation or accumulation of heavy metals, leading to, i.a. DNA damage and cancer development. At the same time, carnosine is considered to be a substance slowing down aging processes of the organism. Moreover, supplementation with carnosine prevents the development of neurodegenerative diseases, cardiovascular diseases and diabetes. It is also recommended to sportsmen and physically active people, as it increases endurance, strength and organism’s efficiency.

Zinc and carnosine and the digestive system
Supplementation with zinc demonstrates wide positive effect on the digestive system. Its deficiency deteriorates epithelial barrier of the digestive system, which may lead to infectious diarrheas. Zinc also limits the secretion of hydrochloric acid in the stomach, therefore it is essential in such diseases as stomach ulcers or reflux disease.

Additionally, carnosine demonstrates positive influence on the state of intestinal mucosa. It turns out that it decreases damages of intestinal villus, which are responsible for the absorption of nutrients from food. Carnosine is therefore recommended to people with a bad state of intestines, caused by excessive inflammation, e.g. people with coeliac syndrome, where we observe impairment of the absorption of mineral ingredients and deep nutritional deficiencies.

Synergistic effect of the active ingredients
In many clinical studies, the combination of carnosine and zinc is characterized by positive influence on the health of the whole digestive system. First of all, they have anti-inflammatory effect, decreasing at the same pro-inflammatory cytokines, e.g. IL-1a, IL-6 in the cells of stomach epithelium, which are prone to the activity of the bacteria  Helicobacter Pylori – responsible for stomach ulcers, bloated stomach and other troublesome ailments.

The combination of carnosine and zinc turns out to be helpful in the protection from a drug called indomethacin. It is a nonsteroidal anti-inflammatory drug used in all diseases of connective tissue. Its side-effect is aggressive interference with intestinal mucosa – indomethacin causes death of GM1 cells, located in intestinal epithelium, which leads to leaky gut syndrome. Supplementation with carnosine and zinc protects from the negative consequences of the application of this drug.

To sum up, Zinc Carnosine Complex with PepZin GI by Doctor’s Best is a dietary supplement containing the combination of carnosine and zinc demonstrating strong, positive influence on health of the digestive system. Synergistic effect of the ingredients enables protection and proper functioning of the stomach, gut and the whole digestive system. It mitigates unpleasant ailments caused by diseases and improper nutrition.

Carnosine (synonyms: L-carnosine, beta-alanyl-L-histidine) is a dipeptide containing the amino acids (beta-alanine and L-histidine) located in the muscle tissue and nerves. It is a potent antioxidant with anti-buffering and chelating properties. It prevents the development of neurological disorders associated with ageing, for use in prevention of cancer, inhibiting the glycosylation and carbonylation processes. Maintains acid-base balance in the muscle tissue contributing to the increase in exercise capacity. It has an impact on the nitrogen metabolism. In the sports supplementation, rare in pure form, more common in preparations containing its precursors - beta-alanine and L-histidine, available at
