Lactobacillus Rhamnosus is a bacterium species that is often included in scientific studies. This bacterium is part of the Lactobacillus family and plays a role in several digestive functions. An adequate amount of these bacterium species in your gut can lead to several potential benefits. You are able to increase your intake of Lactobacillus Rhamnosus through the use of supplements or by turning to foods that contain the bacteria. 

AT A GLANCE: We explain the benefits you may get from an increase in L. Rhamnosus bacterium species in your gut. We also consider potential side-effects that you could experience. 

What Are The Benefits Of Lactobacillus Rhamnosus?

Lactobacillus Rhamnosus is a bacterium essential for the breakdown of lactose. Lactose is a type of sugar that is found in dairy products. The bacteria make a specific enzyme known as lactase. The lactase enzyme is what assists in breaking down lactose sugars. The resulting compound is known as lactic acid. 

We consider a few of the additional benefits that may come with the use of an L. Rhamnosus supplement below:

  • A variety of diarrhea conditions can be effectively treated with a supplement that contains L. Rhamnosus bacterium species. One study shows that bacteria can prevent antibiotic-related diarrhea. This is a very common side-effect in people who need to take antibiotics to treat a bacterial infection. 
  • It has been found that the diversity and number of Lactobacillus bacteria, along with other types, are fewer in people with diagnosed irritable bowel syndrome. One study found that the L. Rhamnosus bacterium species, in particular, seems to be very effective in relieving the symptoms a person may experience due to irritable bowel syndrome. 
  • An imbalance in bacteria may lead to cavities – particularly when there are too many harmful bacteria in the mouth. Studies have also shown that an increase in L. Rhamnosus bacteria in the body could potentially protect against cavities that are generally caused by the presence of bad bacteria. 
  • There is a study that shows the use of a supplement with L. Rhamnosus could potentially reduce appetite and assist in reducing cravings. This may be useful for people who are trying to lose weight. 
  • In one study, it was shown that L. Rhamnosus might be useful in people with reduced insulin sensitivity. 

Possible Side-Effects Of Lactobacillus Rhamnosus

Lactobacillus Rhamnosus does not cause many side-effects. Most people take the supplement without any adverse reactions. There are some who experience abdominal discomfort for a couple of days after they start their first dosage. 

The most common symptoms related to abdominal discomfort is bloating. 

Individuals with a weak immune system, due to the presence of cancer or HIV, might want to avoid the supplement. 


The L. Rhamnosus bacterium probiotic strain is a critical factor in the breakdown of lactose, a type of sugar found in dairy products. There are many studies that show the consumption of food and supplements that contain Lactobacillus Rhamnosus can help the human body. Some side-effects may be experienced, but they are generally mild and go away on their own.
