Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Synopsis: Lactobacillus acidophilus, a probiotic bacterium, has been investigated for its potential role in supporting or treating food allergies, but the evidence is limited and mixed. Several small clinical trials and animal studies have evaluated the use of L. acidophilus, often as part of multi-strain probiotic formulations, in the prevention or management of allergic responses, particularly in children with conditions such as cow's milk allergy or atopic dermatitis. Some studies suggest that probiotics, including acidophilus, may help modulate the immune system by promoting a shift from Th2 to Th1 immune responses and enhancing the intestinal barrier, possibly reducing allergic sensitization and inflammation.

However, the results are inconsistent, with some trials showing modest benefits and others finding no significant effect on food allergy symptoms or tolerance. Meta-analyses and systematic reviews generally conclude that while probiotics may have a role in allergy prevention in early life, evidence for their efficacy in treating established food allergies is insufficient and of low to moderate quality. Most clinical guidelines do not currently recommend L. acidophilus or other probiotics as a standard treatment for food allergies. Therefore, while there is some scientific rationale and preliminary evidence, the overall support for using acidophilus to treat or support food allergies remains limited and not conclusive.
