защита от вируси и бактерии

Saliva has exceptional protective properties and it is no accidentally that our body produces around 1-1.5 liters of it per day. The animals lick their wounds and thus, through saliva, stop the growth of bacteria and other pathogens and treat the affected area. The antimicrobial activity of saliva is due to its naturally content of protein structures, one of which is salivary immunoglobulin A (sIgA), which “sticks” to the virus or bacterium, blocking it and preventing it from further penetrating the body. A-19 supports the natural mechanisms of synthesis of these immunoglobulins in saliva.


A-19 are lozenges. They do not contain sugar and are suitable for diabetics. It can be taken at any time of the day. A-19 is a patented brand, produced in Bulgaria from Bulgarian raw materials. Each batch is subject to strict control and tested in an accredited laboratory. You can buy A-19 on the spot in pharmacies or order online from the pharmacies listed on the site.


If you want to read more details about the mechanism of action of the A-19 you can find the information below.

Immunoglobulin A (IgA)

is one of the classes of antibodies. It is also called secretory because it is secreted (excreted) from the body daily with saliva, which covers the mucous membrane of the oral cavity and its adjacent structures. IgA has the ability to block various pathogens that enter the body through the mouth and nose. Evolutionarily, this mechanism is of great importance, as the mouth and nose are the gateway to many viruses (including respiratory, gastrointestinal, etc.), many bacteria and various pathogens /such as the yeast Candida albicans for example. Therefore, salivary immunoglobulin A (IgA) is defined as the “first line of defense” against pathogenic microorganisms, viruses and bacteria (especially against haemolytic streptococci) . The amount of IgA in saliva is different for each person. The levels of immunoglobulin A in saliva in newborns are insignificant, while in children aged 7 they reach their highest value, which is maintained till middle age. With age and into adulthood, these levels gradually decrease. Low levels of IgA in saliva are considered an indicator of an increased risk of tonsillitis, pharyngitis, respiratory infections, gingivitis, periodontitis, caries, etc.

The enhancement of the antiviral and antifungal activity of saliva significantly limits the pathogens entering the body.

When a pathogen (such as a virus for example) enters the oral cavity, it activates specific cells and receptors in the mucosa, which in turn “provide” information about the aggressor to certain cells of the immune system. Through a series of specific reactions, the immune system “produces” larger amounts of secretory immunoglobulin A (IgA) and “radiates” it back through the mucous membranes and saliva.

A-19 uses this mechanism of action, which affects the natural rise in IgA levels in saliva. It supports local protection in the oral cavity through the natural immune mechanism of immunoglobulin A (IgA) synthesis and an increase in its amount in saliva. Thus, in the event of a threat and the entry of viruses and bacteria or other pathogens into the oral cavity, the mucosa is already prepared and “armed” with additional amounts of IgA to block the pathogen locally, still in place in the oral cavity, and thus prevent its penetration into the body. When taking A-19, each person “makes” the usual antibodies (IgA), which are usually synthesized and excreted daily with saliva, but in larger quantities. This ensures the preservation of the normal individual characteristics of each organism and the maintenance of local immune protection in the oral cavity.

A-19 are lozenges, which is the easiest and most effective way to take. A-19 does not contain sugar, which makes it suitable for diabetics. It does not contain preservatives, dyes, soy, gluten and GMOs.


For the first 5 days, suck 1 tablet twice a day, then only 1 tablet a day or every other day to maintain the result. You can suck at any time of the day. It is important that the tablet melts completely in your mouth and that you do not take liquids or food for at least 20 minutes afterwards. It can also be taken by children if the child can suck on a small candy without choking. For more details on composition and method of administration see Description.
