Overview Of Lactobacillus Rhamnosus Characteristics
Lactobacillus Rhamnosus, also known as Lacticaseibacillus Rhamnosus, is a type of facultatively anaerobic, gram-positive, rod-shaped bacteria that may or may not produce gas.
It belongs to the Lactobacillaceae family within the Firmicutes phylum. L. Rhamnosus is known for its biological properties and is commonly used in various food products and dietary supplements.
Lactobacillus Rhamnosus is one of the bacterial species that exist within the human body. It is primarily known for its role in supporting the digestive system and supplementing beneficial bacteria in the gut [1].
The bacteria is a distinct species within the Lactobacillus genus and has the function of producing lactase enzymes. This enzyme breaks down lactose found in milk into lactic acid.
Is Lactobacillus Rhamnosus Safe?
Lactobacillus Rhamnosus is widely considered safe for consumption due to its extensive use in fermented foods and dietary supplements throughout history.
Both the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have classified L. Rhamnosus as Generally Recognized as Safe (GRAS) or Qualified Presumption of Safety (QPS) [2].
However, when incorporating L. Rhamnosus into food products and supplements, it is crucial to ensure the use of specific and safe strains, as certain strains may present health risks, especially for individuals with compromised immune systems.
Therefore, it is important to exercise caution and select reliable sources when choosing L. Rhamnosus strains for optimal safety and effectiveness.
Health Benefits Of Lactobacillus Rhamnosus
For Adult
Lactobacillus Rhamnosus has been found to have a significant effect in combating bacterial infections, particularly respiratory tract infections.
Its powerful antimicrobial properties help to fight off harmful bacteria and promote a healthy immune system [3].
Additionally, it has been shown to reduce bloating symptoms and improve digestion, making it beneficial for individuals with digestive issues.
In the elderly population, it has been observed to enhance appetite and aid in maintaining a healthy weight [4].
Moreover, this remarkable substance plays a crucial role in controlling blood glucose levels, making it valuable for individuals with diabetes.
Furthermore, it has been shown to help manage cholesterol levels by reducing bad cholesterol and promoting the production of good cholesterol.
With all of these remarkable benefits, it is clear that this substance is a valuable asset in promoting overall health and well-being.
For Baby
Lactobacillus Rhamnosus GG (LGG) helps children combat diarrhea caused by the Rota virus and promotes the development of infants. It reduces symptoms of colic in infants, a syndrome of persistent crying that occurs without a clear cause.
It has the ability to enhance the immune system to prevent weather-related illnesses such as the common cold and flu. Lactobacillus Rhamnosus GG (LGG) supports reducing the incidence of ear infections [5].
Side Effects Of Lactobacillus Rhamnosus
Is Lactobacillus Rhamnosus safe? Are there any side effects of Lactobacillus Rhamnosus. Common side effects of lactobacillus Rhamnosus GG in healthy individuals may include:
- Stomach discomfort or bloating.
- Allergic reactions: hives; difficulty breathing; swelling of your face, lips, tongue, or throat [6].
Do not use lactobacillus Rhamnosus GG if you have certain specific medical conditions, especially Short Bowel Syndrome.
- Individuals with compromised immune systems - such as those with HIV, AIDS, or cancer - should avoid L. Rhamnosus and other probiotics (or probiotic-containing dairy products), as such supplements can cause infections [7].
Similarly, if you are taking medications that can weaken the immune system - such as steroids, cancer treatments, or organ transplant drugs - you should avoid using probiotics.
How Much Lactobacillus Rhamnosus Should I Take?
It is possible to only supplement products containing the L. Rhamnosus strain or these strains combined with other probiotic bacteria.
Probiotic bacteria are measured in terms of the number of live organisms per capsule, known as colony forming units (CFU). A typical L. Rhamnosus supplement contains approximately 10 billion live bacteria, or 10 billion CFU, per capsule [8].
For Adults In General Health
For general health, a supplement containing at least 10 billion live bacteria is sufficient.
To help prevent antibiotic-associated diarrhea, take 2 L. Rhamnosus GG capsules per day, providing 10 billion live bacteria, or 1 capsule containing over 20 billion live bacteria [9].
Supplement with probiotics a few hours after taking antibiotics, and continue for at least one week after the antibiotic course to help restore a healthy gut.
While traveling, take 1 capsule containing at least 10 billion live bacteria twice a day throughout the trip. It is best to start 2 to 3 days before the trip.
For Children
For optimal results, it is recommended to take half to one capsule per day. To consume, simply open the capsule and gently stir the contents into a cool drink of your choice.
Alternatively, you can also mix it with children's food or water to ensure easy ingestion. Enjoy the benefits of this supplement in a convenient and hassle-free manner [10].
