Synopsis

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

Lactobacillus acidophilus is a probiotic bacterium commonly found in the human gut and in fermented foods. Its use for supporting or treating bacterial infections is primarily supported by scientific investigation, though the evidence is modest and condition-specific. Several clinical studies have explored the role of L. acidophilus in preventing or reducing infections, particularly in the gastrointestinal and urogenital tracts. For example, it has been shown to help restore the balance of normal flora disrupted by antibiotics and may decrease the incidence or severity of antibiotic-associated diarrhea and Clostridioides difficile infection. In the context of bacterial vaginosis and recurrent urinary tract infections, some trials suggest that L. acidophilus, alone or in combination with other probiotics, can help restore healthy vaginal flora and reduce infection recurrence.

The proposed mechanisms include competitive inhibition of pathogenic bacteria, production of antimicrobial substances (such as lactic acid and bacteriocins), and modulation of immune responses. However, while laboratory and small-scale clinical studies are promising, large, well-controlled trials are limited, and results are sometimes inconsistent depending on the infection type and population studied. Therefore, while there is some scientific validation for the use of L. acidophilus in the context of bacterial infections, particularly for prevention and adjunctive therapy rather than treatment of active infection, the overall evidence is moderate (rating: 2/5).
