Benefits of the probiotic Lactobacillus Gasseri


In recent years, a probiotic known as Lactobacillus gasseri has gained a lot of popularity and attention. Probiotics, also known as "good bacteria" or "good bacteria," are found naturally in the human body and in certain foods. When taken as a dietary supplement, Lactobacillus gasseri is said to reduce inflammation and offer other health benefits.

Lactobacillus gasseri is a strain of the genus Lactobacillus , a family of bacteria found naturally in the digestive and urinary tracts. Bacteria are believed to help the body by suppressing harmful bacteria, which in turn improves immune function and aids digestion.

Lactobacillus gasseri is just one of several probiotic bacteria, which also include Lactobacillus acidophilus, Lactobacillus rhamnosus, Bifidobacterium , Saccharomyces boulardii, Lactobacillus infanti, and Streptococcus thermophilus.

What is Lactobacillus Gasseri used for?

Probiotics are generally considered beneficial for the health of the digestive system. They also help maintain a healthy vaginal flora and help you lose weight.

For its part, Lactobacillus gasseri is believed to have certain health benefits, either alone or in combination with other probiotic bacteria. These include the prevention of bacterial vaginosis and peptic ulcers , as well as the management of ulcerative colitis , irritable bowel syndrome (IBS), and endometrial pain .

Here are some studies looking at the purported benefits of Lactobacillus gasseri :


Several clinical trials and animal studies have shown that Lactobacillus gasseri can help reduce abdominal fat and promote weight loss .

Among them is a 2013 study published in the British Journal of Nutrition in which 210 obese adults received milk fortified with Lactobacillus gasseri or placebo milk. At 12 weeks, the Lactobacillus group experienced an 8.5 reduction in abdominal fat compared to the placebo group .

Despite the promising results, other studies have not reached the same conclusions.

According to a 2013 study published in the Korean Journal of Family Medicine, 62 obese adults who received a 12-week course of Lactobacillus gasseri did not experience significant weight changes compared to adults who received a placebo.

While the bacterial subtypes used in each study may explain the differences, more research is likely needed to determine the exact role of Lactobacillus gasseri in weight loss and what other factors may contribute, perhaps more significantly.

Vaginal health

Lactobacillus strains are known to promote vaginal health by suppressing harmful bacteria and fungi. However, taking probiotics with food or supplements may not be enough to prevent more persistent vaginal infections.

According to a 2015 study published in BMC Infectious Diseases, Lactobacillus gasseri is much more effective in reducing the recurrence of bacterial vaginosis when taken with suppositories than when taken orally.

Also, the claim that oral probiotics can prevent yeast infections is not always true. This is especially true after antibiotic therapy, when the risk of vaginal yeast infection is high. While Lactobacillus suppositories have been shown to be beneficial in treating yeast infections, foods and supplements rich in probiotics have been shown to be less effective .

On the other hand, Lactobacillus gasseri may help reduce menstrual pain in women with endometriosis , suggests a small study published in the journal Cytotechnology in 2011 .

A study conducted by the Food Institute in Japan involved 66 women with endometriosis who were given either a Lactobacillus gasseri pill or a placebo. Those who administered the probiotic reported a decrease in severe menstrual pain at 12 weeks, although no changes were seen in blood tests or other tests.

Intestinal disease

Lactobacillus is a probiotic bacteria that is believed to help with inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS).

A 2011 review of research published in the journal Ulcers concluded that Lactobacillus gasseri has anti-inflammatory effects on the colon, which may help reduce symptoms of IBS and ulcerative colitis.

It turned out to be less effective in terms of actual prevention of intestinal infections. To this end, probiotic strains such as Lactobacillus rhamnosus and Saccharomyces boulardii are better able to reduce recurrences of IBD or IBS when used in combination with conventional treatments .

H. pylori infection

In a 2014 research review published in PLoS One , scientists evaluated the effect of probiotic supplementation in eradicating Helicobacter pylori ( H. pylori ), a bacterium known to be the leading cause of stomach ulcers .

Based on current research, the H. pylori eradication rate is consistently higher in people who are prescribed antibiotics with probiotics (including Lactobacillus gasseri and Lactobacillus acidophilus ) than those who received antibiotics alone.

It is not known how much Lactobacillus gasseri is more or less effective in treating H. pylori than other probiotic strains.

Possible side effects.

Probiotics like Lactobacillus gasseri are considered safe with little short-term or long-term risk. In some cases, Lactobacillus gasseri can cause side effects such as gas and bloating. Most cases are mild and tend to improve as your body adjusts to the supplement.

Only people with weakened immune systems can avoid Lactobacillus . These include people with advanced HIV infection, organ transplant recipients, and others taking immunosuppressants for cancer and other conditions.

Without a healthy immune system, probiotic bacteria can grow rapidly. In rare cases, Lactobacillus can cause infection in the heart chambers and heart valves .

If you have a weakened immune system or are taking immunosuppressive medications such as prednisone, methotrexate, or sandimmune (cyclosporine), talk to your doctor before taking probiotic supplements.

The use of Lactobacillus in children and during pregnancy or breastfeeding is not well understood. While it is generally considered safe, speak with your pediatrician or OB / GYN to fully understand the benefits and risks (including whether you need a probiotic or not).

Dosage and preparation

Lactobacillus gasseri supplements are available in many grocery stores, drug stores, and health food stores, either as a standalone supplement or as part of a probiotic combination. Lactobacillus vaginal suppositories and capsules are used less frequently in the United States, but can often be found online.

The strength of Lactobacillus products is determined by the number of living organisms in a capsule or tablet. When used to improve digestion or vaginal health, doses of 1 to 10 billion colony forming units (CFUs) per day are considered safe.

Higher doses may be required in the treatment of acute conditions. Examples include:

  • Diarrhea due to antibiotics : 10 to 100 CFU per day in three to four doses.
  • Constipation : 200 to 400 CFU a day in three to four doses.
  • H. pylori infection : up to 15 billion CFU per day with triple antibiotic therapy

What to look for

The United States Food and Drug Administration (FDA) classifies probiotics such as Lactobacillus gasseri as dietary supplements . According to this classification, they do not require clinical research or quality testing to be on store shelves. Because of this, quality can vary from brand to brand, sometimes significantly.

To ensure quality and safety, select only brands that have been tested and certified by an independent certification body, such as the United States Pharmacopeia (USP), ConsumerLab, or NSF International.

Other questions

Do you really need a probiotic?

Unless you have digestive or vaginal health issues, you are likely getting all the probiotic bacteria you need from your diet. Lactobacillus gasseri is also found in some fermented foods such as puba or karima (a staple of Brazil). You can also increase your Lactobacillus intake by eating fermented foods such as yogurt, kefir, miso, kimchi, tempeh, miso, pickles, and sauerkraut.

Even if you find it difficult to maintain regularity (not uncommon with age), you can maintain normal bowel movements with probiotic foods and fiber instead of taking pills. Otherwise, taking probiotics on a daily basis can give you the boost you need.
