What is Lactobacillus Rhamnosus?
Lactobacillus rhamnosus is an extensively studied 'good bacteria' that lives naturally in the body. The vaginal microbiome is also made up of a range of microorganisms, and L. rhamnosus is one of the 'good' bacteria that live alongside other species there.
What does the research say about Lactobacillus Rhamnosus?
Much of the research is on one strain, L. rhamnosus GG (LGG). It has been compared with a low FODMAP diet, and it has been studied in randomised controlled trials in children. L. rhamnosus has also been studied alongside L. helveticus in people taking antibiotics, and a meta-analysis has reviewed the LGG research in this area.
Like other gut bacteria, L. rhamnosus has been studied in relation to the gut-brain axis. Healthy gut microbes produce 'short-chain fatty acids', and researchers are looking at how these and other compounds may influence the brain, including through the neurotransmitter GABA. Animal research has looked at LGG and the gut-brain axis, and a randomised, double-blind, placebo-controlled trial of the L. rhamnosus HN001 strain looked at emotional wellbeing in new mothers who had taken it during pregnancy.
Do remember that gut bacteria need prebiotics as their food. One of the most important prebiotics is Inulin, which can be found in a range of fruit and vegetables.
Form: Live bacteria.

Why it's in pH Hero®
Lactobacillus rhamnosus is another vital strain for both vaginal and gastrointestinal health. This probiotic has strong adhesive properties, allowing it to colonise the epithelial lining of the vagina and gut effectively. In the vagina, it helps balance the microbial population by producing lactic acid, maintaining an acidic pH that discourages the growth of pathogens such as Gardnerella and Candida species. A clinical trial found that Lactobacillus rhamnosus allows stabilisation of the vaginal ecosystem and reduces the recurrence of BV.1 L. rhamnosus also exhibits immunomodulatory effects, promoting a balanced immune response that enhances resistance to infections. In the gastrointestinal tract, it supports mucosal integrity and reduces inflammation, contributing to overall health and reducing systemic effects that could impact vaginal health.
Why it's in Gut Works®
Lactobacillus rhamnosus interacts with the gut epithelial cells, strengthening the intestinal barrier and producing biofilms that protect against pathogen invasion.2 L. rhamnosus influences the gut-brain axis by modulating neurotransmitters such as gamma-aminobutyric acid (GABA), which impacts stress response.3 The research concludes that L. rhamnosus has beneficial effects on IBS symptoms, particularly in diarrhoeal and alternating IBS subtypes. The research advises that L. rhamnosus is recommended for individuals with IBS.4 L. rhamnosus supports the function of and protects the gut barrier,2 which may be one of the main mechanisms of action for reducing the symptoms of IBS.
Lemon Balm
Lemon Balm is acclaimed for helping support relaxation and improving digestion.
Milk Thistle Seed Extract
Milk Thistle supports digestion and helps maintain a healthy liver, protecting and supporting the detoxification of the liver and promoting the body's natural purification.
Psyllium Husk
Psyllium Husk (Plantago ovata) is a fibre and contributes to intestinal tract health and function, helping maintain a healthy bowel and facilitating intestinal transit.
Streptococcus Thermophilus
Streptococcus Thermophilus is a type of ‘good’ bacteria that live in our gut ‘microbiome’ and has a range of healthy functions in our body.
Vitamin B2
Vitamin B2 is an antioxidant, a compound that keeps the number of unstable molecules (known as ‘free radicals') at a healthy level in the body.
Amla Berry
Amla, also known as Indian Gooseberry, can help protect and soothe the oesophageal lining irritated by gastric acid.
Apple
Apples contain pectin which is a unique type of dietary fibre. Pectin is a soluble fibre that supports healthy and normal blood cholesterol levels, and studies also show it can help manage blood glucose.
