Frequently asked questions


1. When should we take Probiotics?

In 21st century the medicine is orientated towards health promotion and prevention of diseases. In this sense probiotics help the positive health and it is good to be taken also in cases when you have no any complaints or diseases available.

Probiotics should be taken in all cases when different factors cause the generation of harmful microbes in great quantities. For example these factors can be taking antibiotics, viral and bacterial infections, after surfeit, physical and mental overstrain, etc.

2. Which bacteria are probiotic?

Microorganisms are divided into three groups:

  • probiotic (beneficial)
  • relatively pathogenic – cause diseases only in cases of reduced immunity of the system
  • causing diseases (pathogens).

The probiotic bacteria divide into three groups: lactobacilli, lactic acid cocci and bifidobacteria. The following probiotic bacteria are widespread and with proven beneficial effects:


Lactic acid cocci


Lactobacillus bulgaricus

Lactobacillus acidophilus

Lactobacillus casei

Lactobacillus plantarum

Lactobacillus rhamnosus

Lactobacillus reuteri

Lactobacillus helveticus

Streptococcus thermophilus

Lactococcus faecium

Lactococcus lactis

Bifidobacterium bifidum

Bifidobacterium longum

Bifidobacterium infantis

Bifidobacterium breve

3. On what do the beneficial properties of the probiotic bacteria depend?

The beneficial effects of the lactic acid bacteria depend on their ability to adhere to the large intestine. More powerful adhesion, more powerful beneficial effects of the bacteria. The researches of a number of scientists as S. Biunchi, H. Chomakov and others, show that L. bulgaricus adheres better than the other probiotic bacteria.

4. What are the curative effects of the probiotic bacteria?

The probiotic bacteria have the following curative effects: they: stimulate the immune system, have anticancerous effect, especially on the large intestine, stop the overgrowth of the harmful bacteria, lower the cholesterol and have antioxidative effect. They are good for the heart and brain diseases, have antihypertensive effect, prevent from urogenital infections, stop the development of helicobacter pylori in cases of ulcers and mycobacterium paratuberculosis in cases of colitis, help the assimilation of lactose. Additionally the probiotic functional food has nutritive and curative effects, as it increases the assimilation of the minerals and the trace elements and the synthesis of vitamins, it intensifies the synthesis of hormones, assimilation of proteins, fats and carbohydrates, it stimulates the growth of the system and detoxificates the liver.

5. What is the difference between bifidobacteria and the lactobacilli as probiotic bacteria?

There are bifidobacteria and lactobacilli into the child’s system. After the age of puberty the amount of the bifidobacteria decreases, and they even fade away in adults, as the lactobacilli predominate over them. The vaginal flora of women that consists of lactobacilli proves this fact. The question if we must settle bifidobacteria in adults additionally provided that in natural conditions the lactobacilli predominate in the human body, has not been studied yet. The lactic acid bacteria produce over 50 % lactic acid from the milk sugar. They are widespread in nature, in milk products, tea, spirits, sausages, pickles, etc. In contrast to the lactobacilli the bifidobacteria produce less lactic acid and produce acetic acid. They are poorly spread and have not been studied enough.

6. What is the difference between Lactobacillus Bulgaricus and the other probiotic bacteria?

Excepting L. bulgaricus, the other probiotic bacteria are permanent occupants of the large intestines of people, swine, monkeys and other animals. They are of animal origin. They get into the system during parturition through the amniotic fluid and the vaginal secretion of the mother. Lactobacillus bulgaricus is of vegetable origin, in nature it is found in the bark of the oak trees, in the blossom of some herbs and flowers, in ants. It gets into the human system through the lactic acid food. There it co-operates with another lactic acid bacterium Str. thermophilus. This symbiosis determines the more powerful immuno-stimulating, anticancerous, anti-atherosclerosis, etc. beneficial effects. Its effects are intensified because only it produces D (–) lactic acid that has considerably more powerful immuno-stimulating, anticancerous, anti-bacterial, etc. beneficial effects as compared to the other lactobacilli. The produced lactic acid makes the conditions for development of the harmful microbes unsuitable. The lactic acid bacteria secrete some other substances beneficial to the organism – bacteriocins, that also suppress the development of the harmful bacteria. They produce substances that have anti-cancerous, antiatherosclerosis, ray protective, antiallergic, antioxidative, etc. beneficial effects. In the last years it was established that Streptococcus thermophilus, found in the original yoghurt, produces alcohol dehydrogenase that serves to break down alcohols.

7. How to choose Probiotic?

It depends on what effect we are looking for. For example, the capsules Laktera and Biomilk contain probiotics, as well as herbal extracts that accelerate the healthful effects additionally. It was specified that Laktera Rose Oil has a powerful antiallergic effect, Biomilk Papaya Vital reduces weight with the help of the additional effect of papaya. The lavender oil in Biomilk Comfort has influence upon the skin diseases. Gin Seng in Laktera Forte protects from gastric ulcer and heals wounds. The probiotic functional food that is not put in capsules, is natural probiotic functional food and can be used as food in cases of serious diseases, as well as preventives or in the beginning of the treatment, seeking for a faster effect. Some of the herbal extracts are unsavoury, therefore they must be taken as capsules.

8. How to preserve Probiotics?

The older methods for probiotic production the probiotics are in liquid state and contain only probiotic bacteria. They must be stored in fridges at temperatures below zero and that makes them inconvenient for mass application. The new methods of production dry the probiotics at a temperature of 50º C below zero and make them in powder. The method of obtaining our probiotics and their storage at a room temperature are object of international protection. Some of the amino acids and the carbohydrates envelop the lactobacilli during the fermentation and keep them alive for more than two years at a temperature of 24º C. Some French companies envelop the probiotic bacteria with synthetic proteins.

9. When should we take Probiotics?

Probiotics should be taken before meal so that the lactobacilli may adhere quickly to the large intestine, to reproduce themselves and to exert their beneficial effects.

10. What is the dose of the Probiotics we should take?

To obtain results we must take more than 100 000 000 probiotic bacteria or colony forming units, which is equal to 2-3 spoons powdered food and 2-8 capsules.

11. Can Probiotics cause addiction?

The addiction as an effect is usually to chemical substances. It has been proved that people addict to all drugs and sedatives. Probiotics are natural products and people do not addict to them. According to the decision of the World Health Organization till 2012 the correlation between the natural and chemical substances should become 60 : 40 in favour of the natural substances because they have much less adverse effects, contraindications and they are not addictive.

12. Can Probiotics be combined with medicines or other probiotics?

People can take different probiotics and combine them without any adverse effects. Probiotics can be combined with medicines. We can choose the most suitable for us depending on the main disease, the season (for example immunostimulators in spring), also it depends on our work and rest (for example in cases of overstrain). Probiotics have preventive effect as they stimulate the immune system and decrease the chances for diseases, caused by relatively pathogenic microorganisms. Probiotics decrease the influence of the pathogens on the basis of competitive relations.

13. How can we see that the probiotics have effect on us?

Having in mind the disease, we must control and follow the clinical and biochemical indices. For example clinical researches show that after taking Biomilk Liponorm for 30 days, the level of the bad cholesterol goes one unit down.

14. Can children take Probiotics?

According to the requirements of the European Union powdered wholefood supplements can be taken by children aged 1 year and above. Children aged 3 and above can take wholefood supplements in capsules. Probiotics without herbal extracts are suitable for children.

15. Can pregnant women take Probiotics?

Probiotics without herbal extracts are suitable for pregnant women and suckling mothers. Powdered probiotic functional foods are more suitable because the gelatinous capsules cause abdominal swelling. Biomilk Ostotonin is the most suitable product because it is enriched with soluble lactic calcium and phosphorous compounds and vitamin D, that enables the rapid and full assimilation of these elements by the mother’s organism as well as by the baby’s organism. This is a protection of the mother against caries, osteoporosis and inflammations.

16. What is the effect of Probiotics on tumours?

Cancerous diseases take up one of the leading positions as a cause for the human mortality. According to the researches made by DOLL and PET in USA there are many things causing cancer; they put in the first place different food – over 35 %, in the second – different infections – about 20 %, then tobaccos. G. Kingston’s researches show that the harmful bacteria Bacteroides lead to formation of a great quantity of carcinogens in the bile and cholesterol in the large intestine. The increased formation of carcinogens is due to excessive consumption of white sugar, refined fats and nitrates. The lactobacilli, Bifidobacteria and the Eu-bacteria are the natural antagonists of the bacteria that form carcinogens. Some researches show that Lactobacillus bulagricus and Streptococcus thermophilus have the most powerful anticancerous effect because they adhere tight to the large intestine and secrete bacteriocins which stop the development of the carcinogenic bacteria. The free bilious acids, cholesterol, nitrates and other carcinogenic agents form insoluble compounds and the organism excretes them with the faeces. The powerful anticancerous effect of Lactobacillus bulgaricus is due to the fact that only it produces D (-) lactic acid and this acid has the most powerful anticancerous effect.

17. How do the Probiotics reduce cholesterol and what is their effect on the atherosclerosis?

Atherosclerosis basically causes different cardio-vascular diseases. It begins slowly and at first it cannot be detected. It develops for many years. Atherosclerosis is due to damages of the blood vessels caused by the cholesterol and triglycerides. Throughout the years they get thicker and narrow. Blood cannot flow through, the quantity of the nutrients and oxygen decreases and this affects and injures the vessels. The narrowed and thick blood vessels become fragile and when something like stress, physical strain, etc. increases the blood pressure the vessels burst, the blood flows out and injures the affected part in the heart, brain or somewhere else. It can cause infarction or stroke. There are some ways to decrease the cholesterol and the triglycerides – as we take unsaturated fatty acids, casein and amino acids, calcium that binds cholesterol into insoluble compounds in the large intestine, antioxidants, fibres. All these anti-cholesterol substances are available in the probiotic functional food Biomilk and Laktera, as they are much more in Biomilk. A number of researches indicate that when taking 25 g Biomilk every day, the level of the total cholesterol, the bad cholesterol and the triglycerides gets 1 - ½ units down for a month. Metabolism can be returned to normal for 5 - 6 months.

18. What is the effect of the Probiotics on the blood pressure ( RR )?

It has been established that the probiotic functional food reduce the blood pressure, as it has an effect on the AC inhibitors and as mentioned above, it reduces cholesterol and triglycerides. We added geranium extract which reduces the blood pressure. Thus our product Laktera RR multiplies the effects of the probiotics and herbal extracts, so people have the chance to take remedies reducing the blood pressure for a long time without any adverse effects.

19. How do the Probiotics heal the liver?

The probiotic functional food Biomilk promotes the healing of the liver in different ways. First of all it reduces the level of cholesterol and the triglycerides and protects it from steatosis, second – it contains all irreplaceable and replaceable amino acids which the liver produces and thus it eases its function, as these amino acids are produced by the lactobacilli. Third – decreasing of the putrefactive processes in the large intestine leads to formation of much less toxic products which the liver must make harmless. Fourthly - it has been proved that the probiotic bacteria and specifically our products purify the system for 6-8 months from viruses and bacteria. Our researches show that the products have healing effect in cases of hepatitis A, B and C. Probably it is due to the fact that these foodstuffs stimulate the immune system. It has been established that the probiotic functional food has an antiallergic effect, as it protects from translocation of the antigens in the blood current. We increased the antiallergic effect as we elaborated the product Laktera Rose Oil, containing the famous Bulgarian rose oil, and as we know this oil has an antiallergic effect and detoxificates the system. Our researches show that this product is good for allergic bronchitis, bronchial asthma, hay fever, etc. It has no adverse effects and in contrast to the medicines people can take it for a long time without interruption.

20. What is the effect of the Probiotics on the immune system?

Over 80 % of the immune system is situated in the abdominal cavity of people. It is the “second brain” of the organism and its job is to organize and support its protection against pathogens, causing different diseases. If the “second brain” functions well, people will live longer without any problems. It has been ascertained that the probiotic bacteria stimulate the immune system as they increase the number and activity of phagocytes, lymphocytes, immunoglobulins, acting as antidote, interferon, protecting against viruses, bacteriocines, protecting against bacteria. They increase the cytokinins production. Thus they strengthen the immunity against different diseases, so people can cope with state of stress and strain. The probiotic bacteria must adhere to the large intestine to realize these effects. As we mentioned above, Lactobacillus bulgaricus adheres best as compared to the other known probiotic bacteria.

21. What is the original Bulgarian yeast for sour milk (Yoghurt )?

Today yoghurt – Bulgarian sour milk – means fermented lactic acid product, obtained under the influence of yeast of Lactobacillus Delbrueskii Bulgaricus and Streptococcus Thermophilus. According to the Codex Allimentaris Standart from 2003 of the World Food Organization the original Bulgarian yoghurt must contain plenty of live bacterial cells of the two microorganisms, it must have a specific scent, taste, consistency and certain biological properties. The two microorganisms, of which the original product is obtained, live separately and independently in nature. Their symbiotic ability occurs only during the fermentation of milk. During this process they promote each other. Lactobacillus Bulgaricus produces more amino acids rapidly because of its great ability to break down proteins. These amino acids promote the rapid reproduction of Streptococcus Thermophilus. On its part Streptococcus Thermophilus synthesizes more pyruvic acid and form, carbon dioxide and other substances, stimulating and promoting the rapid reproduction of Lactobacillus Bulgaricus. The product, obtained after the co-operation between these two bacteria, has specific properties and differs from the other lactic acid products in scent, consistency, acidity, etc. The good bacteria, contained in this product, pass through the gastro-intestinal barrier more easily and a second reproduction of these bacteria occurs in the large intestine. The original yoghurt has more beneficial effects than the other lactic acid products besides all specific nutritive properties mentioned above. Lactobacillus Bulgaricus produces D (-) lactic acid, and it has more powerful immunostimulating, anticarcinogenic, antibacterial, etc. beneficial effects as compared to the other lactobacilli. D (-) lactic acid has undesired effect regarding the metabolism if people take more than 100 mg/kg body weight. This disadvantage is compensated by the L (+) lactic acid, produced by Streptococcus Thermophilus. Thus balance is achieved. The Bulgarian yoghurt and the other lactic acid products contain D (-) lactic acid, which is from 30 % to 50 % of the total contents. These balanced products can be taken by children and older people without any adverse effects.
