LGG Probiotic

Not all Probiotic Strains are Created Equal

Different strains do different things and one must be careful to select the appropriate strain for the intended purpose.1-4 Lactobacillus GG is the most extensively studied probiotic strain5 and helps restore the balance of the microbiota to support better digestive and immune health.  

The History of Lactobacillus GG

Lactobacillus rhamnosus GG (LGG®) is the most extensively studied probiotic strain.1 A naturally occurring, intestinal bacteria that produces health benefits, LGG® survives stomach acid and bile, adheres to human intestinal epithelial cells, and produces an antimicrobial substance6 making this probiotic strain an ideal probiotic for support of digestive and immune health. Since its identification in 1985 by Sherwood Gorbach and Barry Goldin, the probiotic features of LGG® have been recognized in over 1000 scientific studies, including over 200 human clinical trials, making LGG® the most clinically and scientifically studied probiotic strain in the world.5

LGG® Success in the Medical Community

Authoritative medical societies have endorsed the use of LGG® for:

  • Management of acute gastroenteritis14
  • Prevention of nosocomial diarrhea in children15
  • Prevention and treatment of gastrointestinal conditions in children16
  • Prevention of infections in children attending day care17
  • Relief of abdominal pain-related gastrointestinal disorders in childhood18
  • Prevention of antibiotic associated diarrhea in children and adults19

How LGG® works

Probiotics like LGG® are live microorganisms, which when administered in adequate amounts, confers a health benefit on the host6. LGG® promotes the balance of the intestinal microbiota to provide digestive assistance and immune support6.

LGG® exerts its effects by:20

  • Competitively binding to sites where pathogens could
  • Influencing aspects of the epithelial barrier function
  • Blocking proinflammatory molecules
  • Directly releasing antimicrobial substances

All of this activity contributes to the strength of the epithelial barrier, which in turn provides a defense against potential toxins, pathogens, and inflammatory responses.20

The gut microbiota and why it matters

Microbiota are communities of microorganisms that reside within the human body. These communities are composed of bacteria and fungi, among other microorganisms. Working with the immune system, the microbiota plays a critical role in protecting the host from colonization by pathogenic species. And, as part of the gastrointestinal system, gut microbiota aid with metabolism, the proliferation of intestinal endothelial cells, and vitamin synthesis.21, 22 Emerging science has also elucidated the “gut-brain axis,” whereby the microbiota is thought to influence psychological, behavioral, and cognitive functions.23

Roles of the gut microbiota21-23

Disturbances of the gut microbiota have the potential to lead to disease

The micobiota is a delicate ecosystem. Many external factors can disturb the balance, leading to pathogenic invasion, inflammatory responses, and ultimately, disease. For example, antibiotics can kill beneficial bacteria, making hosts vulnerable to pathogenic bacteria, such clostridium.

Disturbances of the microbiota can also lead to inappropriate inflammatory responses. Research has shown that these disturbances may be a cause of irritable bowel syndrome, colitis, and other gastrointestinal disorders.22, 24
