Lactobacillus rhamnosus, a beneficial bacteria, combined with peanut protein was found by Australian Murdoch Children’s Research Institute to accidentally relieve peanut allergies. 

The Journal of Allergy and Clinical Immunology reported an accidental finding with 62 children, looking to see if their intolerance would increase over an 18-month test period, adding peanut protein gradually to the mixture. “A double-blind, placebo-controlled randomized trial of the probiotic Lactobacillus rhamnosus CGMCC 1.3724 and peanut OIT (probiotic and peanut oral immunotherapy [PPOIT]) in children (1-10 years) with peanut allergy. The primary outcome was induction of sustained unresponsiveness 2 to 5 weeks after discontinuation of treatment. Secondary outcomes were desensitization, peanut skin prick test, and specific IgE and specific IgG4 measurements.”

Medical Daily reported, “Over 80 percent of the children who received the treatment were no longer severely allergic to peanuts by the end of the 18 months, when compared to four percent of the placebo group.”

The NIH says, “There are qualitative and quantitative differences in the composition of gut microbiota between patients affected by FA (food allergy) and healthy infants. These findings prompted the concept that specific beneficial bacteria from the human intestinal microflora, designated probiotics, could restore intestinal homeostasis and prevent or alleviate allergy, at least in part by interacting with the intestinal immune cells.”



They go on to say, “Lactobacilli and Bifidobacteria are found more commonly in the composition of the intestinal microflora of non-allergic children and the enhanced presence of these probiotic bacteria in the intestinal microflora seems to correlate with protection against atopy.”

Lactobacillus rhamnosus, is a beneficial bacteria often used in probiotic strains of yogurt.

This study, with the potential threat of dangerous allergy symptoms, was performed with observant medical monitoring and should not be tried outside of proper medical care and observation. 

Lactobacillus rhamnosus GR-1 adheres to intestinal lining as well as the bladder and vaginal walls. Specifically it combats the attachment of pathogenic yeasts. L. rhamnosus produces acid which kills viruses and attacks biofilms but also is anti-inflammatory. 

 The Lawson Health Research Group at the Canadian Research and Development Centre for Probiotics, says, “Lactobacillus rhamnosus GR-1 was originally isolated in 1980 from the distal urethra of a healthy woman. Lactobacillus reuteri RC-14 was originally isolated in 1985 from the vagina of a healthy woman. It was first classified as L. acidophilus RC-14, then renamed as Lactobacillus fermentum RC-14. As the way that bacteria are classified changes with time, the strain was re-named Lactobacillus reuteri in recent years. All the publications with this organism RC-14, were performed on the same bacterium.”



Lactobacillus reuteri RC-14 follows the same properties. They go on to say, “It produces hydrogen peroxide that many believe is important in vaginal health. It also produces signalling factors that disarm toxins produced by Staphylococcus aureus, the bacterium that causes so many hospital infections and death (the ‘superbug’).”

Administration of probiotics needs to be repetitive and deliberate in action, looking for die off symptoms to be sure you are tackling weak strains. Probiotics do not remain in the body long term, they pass through, feeding good bacteria and killing the bad in the process.

The British Journal Of Nutrition reported a study showing L. rhamnosus, “Induced weight loss in women was associated not only with significant reductions in fat mass and circulating leptin concentrations but also with the relative abundance of bacteria of the Lachnospiraceae family in faeces. The present study shows that the Lactobacillus rhamnosus CGMCC1.3724 formulation helps obese women to achieve sustainable weight loss.”



The American Journal Of Clinical Nutrition says, “L. rhamnosus are usually associated with dairy products whereas L. plantarum is found in fermented foods of plant origin.”
