Culturelle Lactobacillus GG, The Scientifically Proven Probiotic That Will Kill Your Yeast, Build Your Immune System, and Help Restore Your Health to Normal

In 1905 Dr. Elie Metchinikoff conducted original research that led to the discovery of the lactobacillus strains of good bacteria. During his research he suggested that consuming lactobacillus rich yogurt could alter the aging process. Consequently, he was responsible for the introduction of L. bulgaricus and Streptococcus thermophilus in yogurt throughout the world.

While his discovery did aid in the treatment of many intestinal disorders including candida yeast infections, it did not achieve the degree of benefit he had thought it would. The reason for this is l. bulgaricus and Streptococcus thermophilus do not repopulate the human intestine since they are not normally found there. However, the study of probiotics and good bacteria for human health was born.

Fast forward to 1985 when Professors Sherwood Gorbach and Barry Goldin with Tufts University School of Medicine were doing research into lactobacillus species and the human digestive system. They were looking for the ideal probiotic candidate that would satisfy Dr. Metchinikoff’s vision. The criteria they set consisted of:

  • It had to be of human origin.

  • It had to be able to attach to the intestinal wall and form colonies.

  • It had to be resistant to acid and bile and survive the journey from the mouth to the intestine.

  • It had to exhibit health-promoting activity in the human body.

  • It had to be safe.

Through their research they discovered and isolated a lactobacillus strain that was later named Lactobacillus G.G ATCC 53103 that naturally occurs in the digestive tract. Since then Lactobacillus G.G has been the most studied strain of good bacteria in the world.

The Scientific Research Behind Culturelle®

Lactobacillus GG (LGG) has shown promising results in treating diarrhea caused by viruses and bacteria in both adults and children. Measurements of intestinal microflora show that LGG adheres to the intestinal wall during healthy periods as well as during episodes of diarrhea. In addition, LGG improves microflora balance, and normalizes fecal enzyme and short-chain fatty acid levels.

In a study performed on 2000 individuals, many of them children, for preventing and treating acute diarrhea and intestinal infections the results are clear. No harmful effects were observed but LGG did stabilize the mucosal lining of the intestine, prevent diarrhea, and reduced antibiotic caused diarrhea and intestinal lining inflammation in infants and adults.

Childhood diarrhea is very common in developed countries, but more so in developing countries, and often results in death. LGG was effective and recorded in studies from Pakistan, Thailand, Estonia, and Italy for the treatment of childhood diarrhea.

Another study involved two groups of participants that were given 400mg of Erythromycin 3 times a day for 7 days. One group received regular yogurt, the other yogurt containing LGG. The number of bowel movements, diarrhea, frequency of stomach pain, and nausea was less frequent in the group receiving the LGG. 75% of those people also had detectable levels of LGG in their stool proving LGG survived antibiotic attack.

In April 2005, doctors Viljanen M and seven colleagues from the Skin and Allergy Hospital, University of Helsinki in Finland, published a study on 230 infants with atopic eczema/dermatitis and a suspected cows milk allergy. They formed 3 groups and gave each one either LGG, a mixture of four other probiotic strains or a placebo for four weeks. They also eliminated dairy from there diets. At the end of the four weeks they reintroduced cows milk proving 120 of the infants were allergic to cows milk.

The researchers concluded, “Treatment with LGG may alleviate atopic eczema/dermatitis syndrome symptoms in IgE-sensitized infants but not in non-IgE-sensitized infants.” In an earlier study of infants with atopic eczema/dermatitis and allergies, the same researchers concluded that LGG treatment might alleviate intestinal inflammation in infants with atopic eczema/dermatitis syndrome and cow’s milk allergy.

Pediatricans E Bruzzese and six colleagues from the Department of Pediatrics, University of Naples Federico II, in Italy measured a marker of intestinal inflammation in 30 children with cystic fibrosis. They also measured the marker in 15 children with active inflammatory bowel disease (IBD) and in 30 healthy controls. Ten of the children with cystic fibrosis received LGG and then the inflammatory marker was measured again four weeks later. According to the researchers, “Intestinal inflammation is a major feature of cystic fibrosis and is reduced by probiotics. The latter finding suggests that intestinal microflora play a major role in intestinal inflammation in cystic fibrosis children.”

An animal study suggested that LGG increased the effectiveness of Glutathione S-transferases (GSTs) to protect the body against harmful compounds and environmental toxins.

A study was done on rats with rheumatoid arthritis. They divided the animals into six groups and fed them either heat-killed Lactobacillus GG, live LGG, sterilized milk, plain yogurt, yogurt-containing LGG, or sterilized water. The researchers concluded, “Our observation of the remarkable preventive and curative effect on arthritis using commercial yogurts containing lactobacilli, especially LGG, suggests the need for investigation of these agents in arthritic patients.”

Microbiologist Hamilton-Miller JM from Department of Medical Microbiology, University College Medical School in the UK discovered that various types of the lactobacilli friendly bacteria inhibit or kill H. pylori and prevent its adhesion to cells. In vivo models have demonstrated that pre-treatment with a probiotic can prevent H. pylori infections. Studies also have shown that administration of probiotics markedly reduces an existing infection. The study also showed that patients given LGG while taking modern prescription drugs for h pylori tolerated the drugs much better than those that don’t.

Japanese researchers explored another possible effect of Lactobacillus GG. They induced diabetes in rats, then fed the animals LGG or a control diet from nine to 18 weeks of age. Lactobacillus GG not only lowered levels of glycosylated hemoglobin, it also improved glucose tolerance in the animals.

Probiotics such as Lactobacillus GG, Bifidobacterium, and Lactobacillus acidophilus significantly reduce the amount of pathogenic bacteria that inhabit the nasal passages, according to a recent study. According to the researchers, the results indicate that regular intake of probiotics can reduce potentially pathogenic bacteria in the upper respiratory tract. The results also indicate a linkage of the lymphoid tissue between the gut and the upper respiratory tract.

According to a new study, consuming a dietary supplement containing probiotic bacteria plus vitamins and minerals for at least three months may reduce the incidence and the severity of common cold and flu symptoms. According to the researchers, “These data indicate that the intake of a dietary supplement containing probiotic bacteria plus vitamins and minerals during a period of at least three months in winter/spring may reduce the incidence and the severity of symptoms in common cold infections in otherwise healthy adults. This may be due to stimulated cellular immunity.”

Pediatricians Rautava S, Kalliomäki M, and Isolauri E from the Department of Pediatrics, University of Turku, in Finland have discovered that giving probiotics to pregnant and lactating mothers increased the immunoprotective potential of breast milk and protected the infants against atopic eczema during the first 2 years of life.

The Benefits of Lactobacillus GG in Review

  • Reduces stomach upset and inflammation in all cases of stomach illness.

  • Successfully treats diarrhea both in children and adults. Helps alleviate eczema and atropic dermatitis

  • Prevents and kills h. pylori.

  •  Helps reduce and stabilize blood sugar levels in diabetic individuals.

  •  It’s beneficial for arthritic patients.

  •  It reduces harmful bacteria in the respiratory tract.

  •  It reduces the incidence and severity of colds and flu’s.

  • It boosts immune properties of breast milk and prevents eczema in infants for up to two years.

  • It helps to heal leaky gut syndrome.

  •  It does not have to be refrigerated so it won’t spoil and grow mold.

  • It can survive antibiotic attack!

  • These last three benefits as far as yeast infection sufferers are concerned are extremely important. Just the fact that most probiotics say you have to refrigerate them suggests they spoil. What happens to food when it spoils? It molds of course, and molds kill good bacteria.

The fact that it survives antibiotic attack also is a blessing for every woman on the planet that has ever, or will ever, take an antibiotic for anything again. This would be a great probiotic to take with an antibiotic and after so you didn’t get a yeast infection to start with.

The suggested dose would be 3 capsules a day for one week. For the second week take 2 capsules 2 x a day. The third week take 3 capsules 3 x a day for 30 days. After this protocol you could take 1 or 2 capsules a day for maintenance and long term prevention of relapse.

Lactobacillus GG has one drawback. The product does not contain any bifidobacterium species, the most prevalent strain of bacteria in the human intestine. None-the-less, the research and proven benefits of Lactobacillus GG are impressive.
