Frequently asked questions
concerning probiotics
(and answers !!!!!)
1. The bacteria contained in
Infantiflora and Intestiflora
are said to be of human origin. When and from whom were they isolated?
They were isolated from healthy persons many years ago ( names or surnames
are never given in Culture Collections Catalogs) and were checked for a number
of probiotic properties, such as:
- the production of anti-microbial substances (anti-bacterial,
anti-viral and anti-fungal);
- the ability to stimulate the human immune system;
- the ability to produce vitamins and growth factors;
- the ability to regulate intestinal transit of food;
- improvement in lactose digestion;
- resistance to hydrochloric acid present in the stomach;
- resistance to bile;
- the ability to assimilate cholesterol;
- the ability to colonize human intestines;
- the ability to modify or remove mutagenic and/or carcinogenic
substances from the intestinal tract;
- the ability to reduce the inflammation of the intestinal epithelium;
- the ability to reduce increased intestinal permeability.
After numerous passages through artificial bacteriological media, such
strains with confirmed probiotic properties were selected and deposited at
reputable Type Culture Collections (e.g. in the USA, Germany, Holland or UK).
The actual strain numbers of our cultures constitute intellectual property of Bioflora
and Agricultural Research Council and cannot be disclosed.
2. What are the side effects of Intestiflora
and Infantiflora?
No adverse side effects have been
reported for probiotic products if taken at indicated quantities. With a
significant overdose of these products, the presence of loose stools was
observed. When the intake of probiotic products is decreased, stools return to
normal consistency.
3. What effect do they have on other
medicines?
To the best of our knowledge there are no known adverse effects.
4. For how long should they be taken?
There is no single answer to this question. Probiotics are not medicines
and should not be treated as such.
The duration of probiotic therapy will depend on a number of factors such as:
- the duration of the condition/conditions for which the remedy is
sought prior to the probiotic therapy;
- the severity of the condition/conditions;
- patient’s diet (high or low in oligosaccharides);
- patient’s age (some probiotic bacteria, especially Bifidobacteria,
disappear from the human digestive track with age);
- stress level in patient’s life;
- the number of previous antibiotic/steroid therapies
- the overall health status of the patient.
5. Contraindications to the
administration of probiotics;
NONE have been indicated in the literature. In our opinion, -severely
immuno-compromised patients should perhaps avoid taking high numbers of
probiotic bacteria, as the possibility of their translocation has not been
completely elucidated or ruled out.
6. Why should probiotic products be
encapsulated and not in tablet form?
Encapsulation offers better protection during storage (i.e. protection
against the exposure to moisture and oxygen) and during passage through the
digestive tract (a very acidic environment in the stomach). The protection is
enhanced if gelatin capsules are pre-treated (hardened) by the process of
freezing.
It should be stressed that some processes of tablet production are carried
out at high temperatures and may result in the decrease of the viable count of
probiotic preparations.
7. Why should probiotic products be
taken on an empty stomach?
- to avoid mixing with food (if entangled in the food matrix these
bacteria can be simply excreted);
- to avoid stimulation of the digestive enzyme secretion, which
accompanies the entry of food into the stomach and which could have an
adverse effect on probiotic preparations.
8. These bacteria live naturally in
the intestines of humans at a temperature of about 37°C . Why then should
these capsules be stored below 8°C?
The lyophilized bacteria present in Intestiflora
and Infantiflora capsules are in the so-called
"suspended-life" state. In the presence of moisture, at a
temperature of 37°C, (which is the optimum growth temperature), the
probiotic bacteria may revive. As they do not have enough nutrients in the
capsule they will die. As they do not grow/multiply at temperatures below
8°C, maintaining them at these temperatures and at the same time
depriving them of moisture (silica gel provided in each container)
maximizes their survival.
9.The bacteria in these capsules are also found in yoghurt. Is it not better to
take yoghurt?
- No, it is not true that these
bacteria are generally found in yoghurt.
Other lactic acids bacteria, with different characteristics- such as:
the ability to produce esters, the ability to rapidly acidify milk and
to produce specific aroma, are used for the production of yoghurt;
- Bacteria used for the production of
yoghurt are not of human origin, i.e. they were not isolated from a
healthy human intestine;
- Bacteria generally used for the
production of yoghurt - do not posses "probiotic properties
listed in the answer to question No 1,
among others do not have the ability to colonize the human intestines.
The yoghurt bacteria constitute the so-called "transient
intestinal flora";
- Although yoghurt is a healthy
beverage and contains lactic acid, one would have to drink 1
000-10 000 liters of yoghurt to have the same number of bacteria which
are present in a single capsule. Due to the low pH of yoghurt and to
usually long time period between production and consumption, the
probiotic bacteria, if used for the manufacturing of yoghurt die and
their number cannot be controlled .
- In view of the above, it is better
and more effective to take capsules containing known, high numbers of
probiotic bacteria.
10.Is Intestiflora safe for use during pregnancy?
YES, it is safe and beneficial for an
expecting mother to take Intestiflora during pregnancy. Not only it is
beneficial for her, but also she can pass Bifidobacteria (present in Intestiflora)
to her baby during natural birth.
11. What if
these bacteria are absorbed into the blood stream from the GIT?
It is not highly probable among the normal population, but may happen among
the ICU patients and among the severely immuno-compromised patients. In such
cases any micro-organism present in the GIT tract could be translocated into
the blood stream.
12. Will these
bacteria be absorbed into the blood stream from open wounds like ulcers or
damaged skin like nappy rash?
It is not very probable. If such a
transfer took place, the human immune system would deal with the
"invading" bacteria.
13. The bacteria in Intestiflora
dwell in the intestines. By what mechanism are they able to combat vaginal
candidiasis?
In a healthy vagina, microflora is normally dominated by lactic acid
-bacteria (e.g. by bacteria of the genera Lactobacillus and
Bifidobacterium), the flora which is responsible for maintaining a healthy
vaginal mucosa and for preventing pathogenic microorganisms from multiplying
and colonizing the area.
Normal vaginal flora can be lost or its balance can be disturbed by:
- antibiotic or steroid therapy;
- frequent douching with chemicals or bathing using various
disinfectants, foams, fragrances etc.;
- the use of deodorant sprays;
- the use of laundry soaps and fabric softeners (which can also
lead to vulvar irritation).
When Intestiflora is administered orally, both groups of probiotic
bacteria supplied in Intestiflora capsules (i.e., Lactobacilli
and Bifidobacteria ) will be present in the GIT and in the bowel. The
probiotic bacteria- can be easily transferred externally (e.g. in a bath, in a
toilet) from the rectum to the vagina due to close anatomical proximity of
these organs. Once they reach the vagina, they should multiply very fast
(doubling time is approximately 30-40 min) and restore the lost vaginal
microflora and the lost microbalance.
Lactic acid bacteria, particularly strains with proven probiotic properties
such as those used in manufacturing of Intestiflora(-and of Vagiforte),
prevent the majority of pathogenic bacteria, viruses, fungi or protozoa from
multiplying and becoming dominant.
Currently accepted mechanisms by which probiotic bacteria maintain their
dominance include:
- the production in situ of antimicrobial
compounds (such as lactic, acetic or formic acid) which results
in/leads to the maintaining of low pH (pH 3,8 to 4,5) in the
vagina or of H2O2 which inhibits the growth
of the majority of pathogenic bacteria invading the vagina and of
the overgrowth of Candida albicans;
- the competition for nutrients and adhesion sites in the vagina.
(Probiotic strains are selected among others for their ability to
become attached to the human intestinal and vaginal mucosa and to
colonize it).
In addition, the presence of probiotic Lactobacilli and Bifidobacteria
in the GIT should significantly decrease the numbers of C. albicans (occurring
naturally in the intestines), thus lowering the chances of
repeated "re-infections" originating from the bowel.
The general stimulation of the immune system by probiotic bacteria present
in the intestines via MALT (Mucosa-Associated Lymphoid Tissue) system, should
also have beneficial effects on fighting bacterial or fungal vaginal
infections.
14. Are these bacteria antibiotic resistant? If not, won’t they be killed
if taken together with antibiotics?
They are not antibiotic resistant and they
should not be taken with antibiotics.
Yes, they will be killed by wide spectrum antibiotics and by the antibiotics
capable of killing Gram-positive bacteria.
If probiotic bacteria were antibiotic resistant, they could transfer this
property to pathogenic bacteria present in the digestive tract
by one or more of the known mechanisms.
15 . Why should
we protect Infantiflora
from air and moisture when on administration, the contents are to be mixed
with liquids?
Because in the presence of air and
moisture the probiotic bacteria present in the capsules might become alive. If
they become alive while still being in a capsule, they would die due to the
lack of nutrients. When the bacteria revive in the digestive tract in the
presence of water, they have more than sufficient amount of nutrients
available to them for maintenance and multiplication.
16. What effect
do the infant’s acidic gastric juices have on Infantiflora?
The infant produces smaller amounts of gastric juices (remember, the
infants are not digesting mother’s antibodies present in the colostrum) than
an adult and for that reason fewer bacteria will be killed. The bacteria
present in Infantiflora, administered without the protection of the
capsule, have been found to be effective .
17. Where
exactly in the GIT do the bacteria contained in Intestiflora
and Infantiflora
live?
Lactobacillus
resides in the small intestine (particularly in the lower part) and -Bifidobacterium
resides in the colon. Both groups of bacteria live predominantly on the
internal surface of the intestines, in the mucus lining the intestinal
epithelium. They can be also present in the intestinal lumen. In addition,
both types live in the mouth, where, by maintaining correct microbial balance,
they protect the host against pathological bacteria yeast and virueses.
18. What is the maintenance dose?
Usually one capsule a day.
19. By what mechanisms can the bacteria
present in Intestiflora
combat oral thrush?
The microflora of a healthy mouth is normally dominated by lactic acid
bacteria (e.g. by bacteria of the genera Lactobacillus and
Bifidobacterium). These bacteria are responsible for maintaining a healthy
oral mucosa and for preventing pathogenic microorganisms from multiplying and
colonizing the area.
Normal oral flora can be lost or its balance can be disturbed by:
- antibiotic or steroid therapy;
- the use of some mouth washes (e.g. Hibitane, Betadine);
- the use of tooth paste containing strong anti-bacterial
substances;
- the advancing age or general lowering of immunity.
Lactic acid bacteria, particularly strains with proven probiotic properties
such as those used in manufacturing of- Intestiflora, can prevent the
majority of pathogenic bacteria, viruses and fungi from multiplying and
becoming dominant.
Currently accepted mechanisms by which probiotic bacteria maintain their
dominance include:
- the production in situ of antimicrobial
compounds (such as lactic, acetic or formic acid) which leads to
the low pH (pH 3,8 to 4,5) in the mouth or the production of H2O2
which inhibits the growth of the majority of pathogenic
bacteria invading the mouth and of the overgrowth of Candida
albicans;
- the
competition for nutrients and adhesion sites in the mouth. (Probiotic
strains are selected among others for their ability to become
attached to the human mucosa and to colonize it).
The general stimulation of the immune system by probiotic bacteria present
in the intestines via MALT (Mucosa-Associated Lymphoid Tissue) system, should
also have beneficial effects on fighting bacterial or fungal oral infections.
In severe cases it is recommended to spread the contents of one capsule
directly in the mouth and repeat two or three times a day.
It should be stressed that young infants should not be given orally any
products comprising Lactobacillus cultures. Lactobacilli produce
a form of lactic acid [D (-) lactic acid] which is not easily metabolized by
infants less than one year of age and which can lead to the development of
metabolic acidosis during the first year of development.
20. Probiotic
bacteria and the enhanced intestinal permeability (intestinal
hyperpermeability)
Intestinal hyperpermeability can be caused, inter alia,
by malnutrition, inflammatory conditions, surgery, trauma, sepsis, cold shock,
starvation, immuno-suppression, endotoxaemia or chemotherapy. Poverty and
unhygienic living conditions further increase the extent of the problem.
Gastrointestinal hyperpermeability can, in turn, lead to the excessive
translocation of certain molecules and microorganisms. When the translocation is
minimal, the body’s immune system has the ability to deal with it. However, a
pathological increase in gut permeability can have serious consequences and can
for instance give rise to gastrointestinal- disturbances, ranging from mild to
severe, which in turn can lead to toxaemia, septicaemia and even death.
In a number of investigations, probiotic bacteria were found:
- to stabilize the gut mucosal barrier;
- to down-regulate intestinal inflammation;
- to repair damage to the intestinal epithelium.
Probiotic bacteria as well as a
number of amino acids have been shown to play a major role in both the
maintenance of the normal gastrointestinal barrier and in the reversal of the
hyperpermeability state.
