Lactobacillus Plantarum is a probiotic which is good bacteria that can lead to an improvement in health. It is from the largest genus of the lactic acid bacteria group, Lactobacillus, which has over 50 species.Lactobacillus Plantarum is one of the most versatile species as it benefits both humans and animals. To this day, it continues to be the subject of many studies. These studies show that it can positively affect multiple symptoms and disease processes. It was first isolated from human saliva and can be found in our mouths and our intestinal microflora. This certain species is even able to survive in the extreme environment of our GI tract for a long period of time. The human GI tract inhibits the growth of many pathogenic bacteria which cannot tolerate high acidity because of its extremely acidic environment with a low pH balance. This probiotic works by stopping the spread of these pathogenic bacteria to other locations in the body. If there is an imbalance of bacteria in the gut, bad bacteria has a chance to colonize and spread to other parts of the body and begin infection. Lactobacillus plantarum produces hydrogen peroxide which kills bad bacteria and ceases the colonization. It is resistant to most antibiotics which makes it a good choice of probiotic supplementation during and after a course of antibiotic therapy.

There are many benefits of Lactobacillus Plantarum other than the ones already stated. Research has shown that L. Plantarum works to reduce or prevent inflammation in the epithelial lining of the intestines by maintaining the epithelial barrier and inhibiting inflammatory responses. People with Crohn’s disease, Inflammatory Bowel Disease (IBD), and colitis often have this type of inflammation. Supplementing with this probiotic can restore proper digestive health, stop constipation or diarrhea, and improve the immune system.

L. Plantarum can be found in a number of fermented foods such as kimchi, brined olives, pickles, and sourdough. Lactobacillus in general can be found in yogurt and other cultured foods. The recommended dosage depends on the symptoms being treated but a typical dose is usually 10 billion viable cells taken 1-2 times a day.
