Lactose intolerance is one of the most common food allergies; symptoms range from mild discomfort to extreme intestinal pain. Complete avoidance of dairy is perhaps the easiest way to avoid these concerns, especially for young children. However, it might not be the only option. According to a recent study, infants with lactose intolerance, when given a specific probiotic strain, were able to tolerate lactose and even reverse their cow’s milk allergy.
Does Lactobacillus rhamnosus Combat Lactose Intolerance?
The specific strain that shows promise in lactose intolerance is Lactobacillus rhamnosus, a Gram-positive anaerobe probiotic bacteria. When administered to lactose-intolerant infants, the bacteria colonized the intestinal tract and produced positive changes within the gut microbiota. Changes in the gut helped the infants handle cow’s milk formula without issue.
Could these findings translate into people of all ages? We’ve known for years that probiotics support digestion and improve the absorption of nutrients, so it shouldn’t come as any surprise to point out a specific strain that helps with lactose intolerance. Environmental pollutants and pesticides have been connected to the depletion of probiotics in the gut microbiome, potentially explaining the correlating rise in lactose intolerance cases. Antibiotic use has also risen and has become a huge health issue that is likely associated with the dwindling probiotic levels in the population. 
How to Use Probiotics for Lactose Intolerance
While this research is great news, everyone's body is different and there's no guarantee every lactose intolerant person on the planet will have the same results. That said, take caution before using probiotics for lactose intolerance, gluten intolerance, or other food allergies. If it's something you're interested in, you can find this strain and others in our newest probiotic formula Floratrex™.
