L. Paracasei is one of the many strains of friendly bacteria that are being used for health benefits.



  • Lactobacillus paracasei  is a gram-positive lactic acid bacterium, commonly used in dairy products and probiotics


  • Dietary supplementation with cow’s milk or rice fermented with L. paracasei  prevents common infectious disease (CIDs) in children attending daycare. L. paracasei  is an enhancer of systemic immunity in mice. This bacterium skews the Th1/Th2 balance toward Th1 through the elevation of Th1 cytokine production.
  • L. paracasei  induces Th1 and regulatory responses in mice, suppresses airway inflammation and down-regulates allergen-specific immune responses.
  • L. paracasei  inhibits common pathogens including Shigella dysenteriae, Staphylococcus aureus, Cronobacter sakazakii, Escherichia coli, and Candida albicans in the laboratory.
  • Beneficial for dental health
  • Improves intestinal microflora
  • May better liver function
  • L. paracasei  symbiotic improves many aspects of insulin resistance, such as fasting response, hormonal homeostasis, and glycemic control in rats.
  • Combats obesity
  • L. paracasei  contributes to the reinforcement of skin barrier function, inhibits water loss, decreases skin sensitivity and modulates the skin immune system leading to the preservation of skin homeostasis.


  • Like almost all probiotic species, Lactobacillus paracasei is in itself a harmless bacterium that simply adheres to your mucosal lining, helps you digest food, and keeps ‘bad’ bacteria in check when they threaten your overall health.
  • If you are a healthy, doctor-‘approved’ individual, then you most likely have the green light for Lactobacillus paracasei consumption in any shape, way or form. At worst, you might experience some abdominal discomfort in the shape of distention (bloating), gas, and irregular bowel motility, but these symptoms should go away within a few days tops.


  • Extreme care should be given for patients who suffer from innate or acquired immunodeficiency of any kind.  Lactobacillus paracasei cultures should be avoided if you have a weakened immunity response, are undergoing immunosuppressant therapy or have been recently involved in an organ transplant procedure.
  • These situations have a negative reputation of enabling bacterial translocation and therefore leading to medical complications and even sepsis. Caution is equally urged if you are receiving antidepressant treatment or are a pregnant/ nursing mother.
