Attack, which delicately called a "problem with the stomach and intestines", always overtakes a person at the wrong time and the wrong place. So better to go to the trouble of finding the right means to eliminate it.

Disruption of the normal intestinal microflora is a common problem. Fortunately, for the treatment of dysbiosis, there are dozens of drugs that are freely sold in pharmacies. Appeared and a new generation of drugs — synbiotics. Which one to choose? The one that meets five criteria listed below.

First criterion: the presence of prebiotic in the composition of medicines
In the composition of the medicine must be both probiotics and prebiotics. It is only when combined product has the right to be called a synbiotic. To win beneficial intestinal microflora harmful over she needs supply: it is necessary for the growth and reproduction of "good" bacteria. Prebiotics (indigestible carbohydrates) and there is food.

The prebiotics include lactulose, fructo-oligosaccharides, glucose, oligofructose. All these substances are found in many products. For example, oligofructose found in wheat, onions, bananas, honey, garlic, and its fermentation in the colon causes numerous physiological effects including the increase in the number of beneficial bacteria.

If in the human diet few foods rich in prebiotics, good bacteria don't receive the necessary nutrition, begins to starve and die.

The second criterion: a variety of probiotic species
Probiotics are, in fact, have beneficial bacteria. The more and the greater their diversity, the better. In different parts of the human intestine is home to a variety of strains of microorganisms. Lactobacillus, Lactococcus and thermophilic lactic streptococci (Streptococcus thermophilus) more often live in the small intestine, and bifidobacteria — in the large. In modern synbiotics contain from 2 up to 9 different strains of bifidobacteria and lactobacilli. Before you buy a synbiotic, look at an annotation: the drug should contain various strains of microorganisms. The more the better, then its action will be most effective. Choosing a synbiotic, you need to ensure that the strains of bacteria it contains, is well studied and safe. These are various types of lactobacilli, the instructions may be listed as Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus bulgaricus, Lactobacillus plantarum, Lactobacillus salivarius, Lactobacillus rhamnosus, Lactobacillus reuteri), Bifidobacterium (Bifidobacterium bifidum, Bifidobacterium longum, Bifidobacterium breve, Bifidobacterium infantis, Bifidobacterium adolescentis), thermophilic (lactic acid) streptococci (Streptococcus thermophilus).

The third criterion: the number of bacteria
The higher the concentration of beneficial bacteria in the structure of the symbiotic, the more effective the tool. A daily dose of live microorganisms should be at least 107 CFU (colony forming units of bacteria). SOME of the indicator of number of viable microorganisms in one dose. For example, indicator 1 x 109 means that a single dose of 1 billion colony forming units of beneficial bacteria, each of which forms in the intestine their own colony of microorganisms.

Criterion four: protection of bacteria
For restoration of microflora is important that the beneficial bacteria gets precisely to the location of the pathological focus. In the human body is the colon. But on their way there are at least three natural barriers: the acid environment of the stomach, bile salts and pancreatic enzymes. Under their influence the microorganisms can die prematurely without ever having done his good deed. Only a small number of strains of lacto - and bifidobacteria, has acid resistance, and the efficacy of synbiotic largely depends on how secure its components. And this, in turn, depends on the shape of the issue. For example, tablets or beneficial bacteria, available in liquid form will not guarantee their safety. So it is better to buy synbiotics, the production of which manufacturers use protective technologies.

The fifth criterion, additional: convenient storage and use
Bacteria are tender, and the drugs with them require special storage conditions. If you violate, for example, temperature, microorganisms will die. This is especially true with liquid forms of medications. It is better to abandon the funds that have a long shelf life (more than 3-4 years). This means that in their manufacture are used preservatives, but they do not affect the activity of the bacteria. Modern technologies allow to store some of synbiotics at room temperature. And preservation of beneficial bacteria and transportation, and during storage in the pharmacy and at home it is guaranteed. This is especially important if you plan to take a synbiotic.

An important factor is the frequency of reception. How often do we not put promyvaem course completely, forgetting to take another "pill"! Low frequency reception is very convenient and saves you from many problems. Took some medication and forget about it for the whole day.
