Indications & Uses

Lactobacillus Rhamnosus GG is a probiotic. Probiotics contain different types of micro-organisms, such as yeast (Saccharomyces boulardii) and bacteria (such as Lactobacillus and Bifidobacterium). Micro-organisms like these, also called flora, are naturally found in the stomach, intestine and vagina. Some conditions, such as antibiotic use or travel, can change the normal balance of bacteria and yeast. Probiotics are used to improve digestion and restore the normal flora. They have also been used to treat bowel problems (such as diarrhea and irritable bowel), eczema, vaginal yeast infections, lactose intolerance and urinary tract infections.

Pharmacology

Lactobacillus rhamnosus GG resists bile and acid, so it isn't easily destroyed in the gut. It can build a healthy population there and stick to the gut lining. It can also stop other bacteria from growing, because it competes with them for nutrients and for attachment sites on the lining. If there isn't enough food, harmful bacteria can't live inside.

The human gut lining acts as a barrier between the food, toxins and microbes in the intestine, the body cavity and the bloodstream. The lining is held together by cells called tight junctions. When the lining is damaged, the tight junctions loosen, and harmful compounds can leak into the bloodstream. Lactobacillus rhamnosus GG can stimulate different reactions in the gut that make these tight junctions work better.

These bacteria might also help people with inflammatory bowel diseases like ulcerative colitis, since damage to the gut lining is a common complication of inflammatory bowel disease. Probiotics don't cure inflammatory bowel disease, but they can help replenish friendly bacteria and make the junctions tighter.

The bacteria can also bind to proteins on immune cells, and this activates the immune system. Once they bind, your body is signalled to release chemicals that influence other immune cells and regulate the immune response.

If anyone loses friendly bacteria, or has an imbalance caused by a medicine, an infection, or a bowel disease or syndrome, taking Lactobacillus rhamnosus GG can help build back a healthy microbiome.
