Lactobacillus rhamnosus GG

Lactobacillus rhamnosus GG is a strain of Lactobacillus rhamnosus, a species of Lactic acid bacteria that was first isolated from the human intestinal tract. This strain is commercially used in many dietary supplements and fermented foods due to its potential health benefits.

History

Lactobacillus rhamnosus GG was discovered in 1983 by Sherwood Gorbach and Barry Goldin. The "GG" in its name represents the initials of these two scientists. They identified this strain as particularly robust and capable of surviving in the human Gastrointestinal tract.

Characteristics

Lactobacillus rhamnosus GG is a Gram-positive, facultative anaerobic bacterium. It is rod-shaped and occurs in chains or pairs. This strain is acid- and bile-stable, allowing it to survive the harsh conditions of the stomach and intestines.

Health Benefits

Several studies suggest that Lactobacillus rhamnosus GG may have various health benefits. These include:

• Gastrointestinal health: It may help treat and prevent Diarrhea, IBS, and IBD.
• Immune system: It may boost the immune system and help fight off infections.
• Mental health: Some research suggests it may help improve mood and cognitive function.

However, more research is needed to confirm these benefits and understand how Lactobacillus rhamnosus GG works in the body.

Safety and Side Effects

Lactobacillus rhamnosus GG is generally considered safe for most people. However, in rare cases, it may cause side effects like gas, bloating, or upset stomach. People with weakened immune systems or serious illnesses should consult a healthcare provider before taking supplements containing this strain.
