About probiotics

Probiotics are defined as ”live microorganisms that, when administered in adequate amounts, confer a health benefit on the host.” (WHO/FAO 2002, Hill C et al. 2014). An important criterium for qualifying as a true probiotic is that health benefits have been proven in clinical studies. Furthermore, a probiotic product must contain the same bacterial strain(s) and the same dose that was used in the clinical studies.

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Prebiotics are fibres and carbohydrates that stimulate the growth of bacteria in the gastrointestinal tract.

The patented probiotic strains found in BioGaia's products were originally found to live in the human digestive tract, which means they are very well suited to our bacterial flora. Many other probiotic products on the market contain strains that come from plants or animals.

Many people assume that lactic acid comes from dairy because the first word sounds similar to lactose - a sugar naturally found in dairy products. However, lactic acid is not milk, nor does it contain milk.

Lactic acid bacteria have the ability to form lactic acid, which is not the same as milk. Lactic
acid bacteria are also found naturally in many foods, for example, in kimchi, olives and sauerkraut.

Bacteria are classified into genus, species and strains. Probiotic strains of the same species have different characteristics, and may therefore have different health effects. For example, clinical studies with the two strains, Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) ATCC PTA 6475 and Limosilactobacillus reuteri DSM 17938, have shown different effects in clinical studies. That is why a probiotic product must be defined on strain level.

Multi-strain products containing several strains in high doses do not necessarily have a better effect than a single-strain product. Important criteria when choosing a probiotic product are:

  • The probiotic bacteria must be defined on strain level.

  • The probiotic product must have been tested in human clinical studies, with the same dose and with the same bacterial strain(s) as in the commercial product.

Gut health supplements or gut health products are other common names used for probiotic food supplements.

Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) is a probiotic strain that has been tested in more than 150 human clinical studies (May 2020). The scientific designation of L. reuteri Protectis is L. reuteri DSM 17938. Other products containing Limosilactobacillus reuteri include BioGaia Protectis baby drops and BioGaia Protectis tablets.

Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) is a probiotic bacterium that has co-evolved with humans since the beginning of time, and because of that it is adapted to its host. L. reuteri is one of the first bacterial species to naturally become established in the microbiota of the new-born. BioGaia’s probiotic products with L. reuteri are among the most scientifically well-documented probiotics in the world in terms of both efficacy and safety. To date, over 220 clinical studies with BioGaia’s L. reuteri-strains have been performed in approximately 19,000 people of all ages. Positive results have been shown for several gastrointestinal disorders, oral health, and bone health.

The bacteria are alive but in a dormant state. They become activated and fully metabolically active when they come in contact with the saliva. By the time they reach the stomach they can start to colonize.

How to Use Probiotics

Yes, BioGaia products can be taken together with antibiotics. Antibiotics disrupt the natural balance in the gut. As BioGaia products help to maintain a balanced gut microbiota, they may reduce common side effects of antibiotics. We recommend taking the antibiotic two hours before or after the probiotic.

Even an indigenous bacterium like Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) should be taken on a regular basis, since most people of modern society does not get colonized by L. reuteri during infancy. The epithelial lining covers our gastrointestinal tract and works like a skin on the inside of our bodies. The main task of our ”inner skin” is to differentiate between what should be absorbed and what should not be let into our bodies. Biopsies have shown that L. reuteri is temporarily binding to our epithelial lining. However, since the cells in our epithelial lining is replaced every fourth day, the majority of L. reuteri cells are also washed away within a week or so. Since L. reuteri colonization is transient, every day intake is recommended to ensure adequate and stable levels of L. reuteri in the gastrointestinal tract.

It does not matter if BioGaia’s probiotic products are taken with or without food. What is important is to take it on a daily basis. However, products containing Vitamin D should preferably be taken together with food for better uptake.

The recommended daily dose of Limosilactobacillus reuteri (formerly known as Lactobacillus reuteri) Protectis is 100 million CFU (Colony Forming Units). This dose is provided by 5 drops of BioGaia Protectis drops or 1 BioGaia Protectis tablet.

Yes, it is safe to take BioGaia products together with pharmaceuticals and other supplements.*

*If you have any medical conditions, always consult your healthcare professional for advice.

The recommended dose of a probiotic does not depend on bodyweight. BioGaia’s clinical studies show efficacy with the same dose both in children and adults.

Yes, several studies show that it is safe to consume BioGaia's products during pregnancy and breastfeeding.

Since every gastrointestinal tract is unique, some individuals might experience a temporary change in gut motility. BioGaia probiotic products very rarely cause side effects when the recommended dose is taken.

Some individuals might experience gas (flatulence), however, this generally disappears after a few days. No serious adverse effects have been observed in clinical trials up to the maximum tested dosage of 10 billion CFU per day.
