Probiotics and your health: what you need to know. Facts about probiotics and Reuterina®

We examine what probiotics are and how they improve health. We also discuss how Reuterina® is used and highlight the top 10 facts about Reuterina®.

1. Probiotics are “good”, live bacteria.1

Probiotics are live microorganisms (bacteria) that provides a health benefit.1 They live naturally in the intestine, yet are vitally important for gut health.1,7

Lactobacillus reuteri is a species of lactic acid bacteria, which is important for normal gut functions. Lactic acid bacteria produces lactic acid which helps to stop bad bacteria.7b

Lactobacillus reuteri, the probiotic species found in Reuterina® products, also produces reuterin. Reuterin is a natural compound with antimicrobial properties.7

2. Probiotics maintain the balance in gut flora.1

Probiotics, added as a supplement, will have a positive effect on your gut flora patterns. Probiotics further aid the spread of beneficial bacteria.9

Many gut disorders occur due to an imbalance in the normal gut flora, or a lack of diversity in the gut flora.3,9  Illness or medicines upset the balance of flora in the gut. Probiotics restore this balance, because it is important to be as close to the normal flora as possible before the illness or medicine was present.1

3. Probiotics have numerous health-promoting activities.1

Health professionals are increasingly recognising the beneficial effects of probiotics on our health, because probiotics play an important role in immunological, digestive and respiratory functions. They also have a significant effect in alleviating infectious diseases in children as well as other high-risk groups.1

Paediatricians, during the first 6 months of a baby’s life, found colic, reflux, and constipation as the most common conditions they see. These conditions often require hospitalisation, feeding changes, use of medicines, parental anxiety and a loss of parents’ working days.3

Research into the cause of babies’ gut problems has shown gut flora to play a crucial role and many studies focus on probiotic therapy as a treatment for specific conditions affecting the gut.3

4. Reuterina® probiotics reduce crying in colicky babies

Nearly 20 % of all paediatrician visits in the first 4 months of a baby’s life is due to colic in babies. This can lead to parental anxiety as well as exhaustion and stress.3

Gut flora’s role has grown in importance, because colicky infants have lower numbers of the intestinal lactobacilli type of good bacteria, specifically when compared to healthy infants.2,12

Colicky infants showed positive benefits in six clinical studies after Reuterina® drops were provided.2,3,9,10,11a12

Colicky infants, when provided with Reuterina®, also showed a 50 % 9 reduction in daily crying time as well as fussing time.  Reuterina® also starts working within the first week.9 Additionally, Reuterina® improves the quality of life for the family of a colicky baby.10

5. Reuterina® probiotics reduce regurgitation in babies

Nearly 50% of all healthy infants, aged 3 months and younger, regurgitate or vomit at least once a day. Infant regurgitation is also responsible for nearly 25 % of all paediatric consultations.3

A study that included the daily use of Reuterina® early in a baby’s life showed a decrease in regurgitation frequency when compared to babies without probiotics. Reuterina® is well tolerated for this age.3 Reuterina® also has no adverse effects as a probiotic supplement for this age.13 

Using a probiotic supplement during early life also decreases the need for medicines to promote gut comfort.3

6. Reuterina® probiotics improve constipation in babies

Constipation is a common and distressing problem in babies and children, because it also has several implications on the quality of life for both the child and the family.3,5

Laxatives is an effective treatment for only 60 % of constipated children. Many children need long-term therapy for successful constipation treatment.5

Probiotics can treat constipation. Patients with constipation have an imbalance in the gut flora. Probiotics can restore the balance in the gut flora.5

A recent study gave children, who suffered from chronic constipation, Reuterina® drops as probiotic treatment over a period of 8 weeks. The frequency of bowel movements per week increased in infants who received Reuterina®,5 thereby giving clear evidence that Reuterina® works for constipation.5

7. Reuterina® probiotics improve abdominal pain in children.

Children commonly suffer from illnesses related to abdominal pain. Although these illnesses are not life-threatening, they do cause significant anxiety, school absenteeism and frequent doctor visits.  Unfortunately these common abdominal problemshave limited treatment options.4

Reuterina® has been clinically tested in children displaying typical abdominal pain disorders. Reuterina® provided results, after 4 weeks of being given as a supplement, of relief in the frequency and intensity of abdominal pain in children with these illnesses.4

Probiotics work in a complicated manner to reduce abdominal pain; the good bacteria is able to influence how the gut functions and responds to pain sensations.4

8. Probiotics play an important role in immunity.

Probiotics are truly versatile, because they play an important role in digestive functions, but can also have an effect on immune-related functions.1,12

The gut flora may play an important role, because it affects the maturation of the immune system after birth.12

Healthy persons can take probiotics as a means to prevent certain diseases because they stimulate immunity, while being an effective preventative therapy against infections in healthy people.1,13,14

Healthy children attending day care centres were provided with Reuterina®. Children received Reuterina® drops on a daily basis, 5 drops per day, over a period of 6 months. Reuterina® significantly reduced the frequency and duration of diarrhoea and lung infections, as measured after 3 and 6 months of use. The number of doctor’s visits and absenteeism from school was also reduced.14

9. The benefits of probiotics are species-specific.

It is important to know that different types of probiotics have different health effects.4

There are many varieties and species of probiotics that have different characteristics and effects, because the proven effect of one strain or species is not necessarily the same as another strain or species.4

The best probiotic should have proven effects as well as benefits for the condition(s) you are preventing or treating.1,12

The bacteria used in Reuterina® is from the species Lactobacillus reuteri and, specifically, the strain DSM 17938. This strain has been clinically tested and also proven in more than 120 clinical trials. It is sold commercially in more than 90 countries worldwide.8,12

10. Reuterina® can be used across all ages and are easy to use.

Probiotics’ safety profile makes them a good alternative for the treatment of specific conditions.12

Reuterina® can be used by individuals of all ages. Five (5) drops are given to babies and young children once per day. It can be dropped straight into the mouth or onto a spoon.13

A chewable tablet is available for older children and adults. This is recommended at a dose of one tablet per day.15,16

Trust the science behind your probiotics.

The probiotic strain in Reuterina®, Lactobacillus reuteri, has been used for many years. Reuterina® is used specifically as a probiotic for adults, children and new-born babies.12 The positive effects of this probiotic on gut disorders, as well as protection from infection, have been well demonstrated.These gut disorders include colic, regurgitation, abdominal pain, constipation and diarrhoea.12

Probiotics are essential for gut health,1 therefore you can trust Reuterina® as a probiotic with multiple benefits. Reuterina® is also suitable for babies, kids and adults, for life!13,15,16
