Lactobacillus rhamnosus GG is a strain of friendly bacteria that was first discovered in 1985. Now, over 30 years later, it has been the subject of over 1,000 clinical studies, making it the number one most studied probiotic strain.1††

But what is it about this beneficial bacteria strain that keeps scientists interested in studying and utilising its potential?

Why is Lactobacillus rhamnosus GG effective?

One of the reasons people keep studying Lactobacillus rhamnosus GG is because it has been proven to be both safe and effective.1  Let’s dive a bit deeper into what makes this strain so effective.

You probably already know that Lactobacillus rhamnosus GG promotes good bacteria in your body,* but you may not know how this occurs. In order to replenish the good bacteria in your body, two key things have to happen – both of which Lactobacillus rhamnosus GG excels at.  First, in order for it to be effective, Lactobacillus rhamnosus GG needs to be welcomed into the human digestive system.

Since Lactobacillus rhamnosus GG occurs naturally in the human body,2  the immune and digestive systems do not see it as a threat or try to reject it from the body. This allows it to enter and stay in the body where it can get to work balancing the good and non-beneficial bacteria in the gut.*

Being accepted in the body is a great start, but once it’s in it also needs to survive the harsh environment that exists there. Luckily, Lactobacillus rhamnosus GG is strong enough to survive harsh stomach acids while being sticky enough to adhere to the intestinal walls.3  Lactobacillus rhamnosus GG is able to stick to the cells of the intestine, thanks in part to its pili, the hair-like structures on the surface of LGG, which are equipped with strain-specific proteins that bind mucus and are required for adherence.*3

What does Lactobacillus rhamnosus GG help with?

It was mentioned earlier that Lactobacillus rhamnosus GG helps to restore balance to the bacteria in the digestive system, ensuring a mix of good and non-beneficial bacteria,* but how do these benefits show themselves in everyday life?

Lactobacillus rhamnosus GG can stake claim to a whole slew of digestive and immune system benefits, such as assisting with:

  • Occasional diarrhoea*
  • Occasional wind and bloating*
  • Supporting digestive and immune systems’ function*
  • Occasional digestive upset*

That’s pretty impressive for a microscopic strain of bacteria.

Culturelle® Biotic supplements

Another feature of Lactobacillus rhamnosus GG that is almost as important as everything it may help is how accessible it is. A daily supplement like Culturelle® Natural Flora® can make getting a daily serving of the probiotic strain Lactobacillus rhamnosus GG easy because it has 100% Lactobacillus rhamnosus GG.*

Each capsule contains 10 billion bio-live cultures of Lactobacillus rhamnosus GG plus Inulin* to help promote growth of beneficial micro-organisms in the intestines.

Culturelle® can be taken with or without food, and the capsules can even be opened and mixed into any cool or room temperature food or beverage.

All of the above make taking Lactobacillus rhamnosus GG a convenient and effective way to support your digestive and immune systems every day.*
