Lactobacillus Plantarum
Snapshot
Lactobacillus plantarum is a versatile probiotic bacterium that supports digestive health, modulates immune responses, and helps maintain microbial balance in the gut.
What is Lactobacillus plantarum?
Lactobacillus plantarum is a Gram-positive, rod-shaped lactic acid bacterium found in fermented foods and the human GI tract; it produces lactic acid and bioactive metabolites that impact gut microbiota.
Where It Comes From
Isolated from sauerkraut, kimchi, sourdough, and pickles, L. plantarum is manufactured for use in probiotic supplements and functional foods worldwide.
Key Nutrients & Compounds
Supplemental L. plantarum delivers live cultures (CFU counts) that produce lactic acid, bacteriocins, and exopolysaccharides, supporting mucosal barrier integrity and inhibiting pathogens.
Health Benefits
L. plantarum enhances nutrient absorption; reduces bloating and gastrointestinal discomfort; supports immune function by modulating cytokine profiles; and may alleviate IBS symptoms.
Recommended Dosage
Effective doses range from 1 to 10 billion CFU per day, taken with meals; follow product-specific instructions for storage and viability.
How to Use It
Consume L. plantarum via capsules, sachets, or fermented foods; store refrigerated if indicated to maintain potency; avoid exposure to high temperatures.
Who Should Use It?
Ideal for individuals with digestive disturbances, immune imbalances, or those seeking to enhance gut microbiome diversity.
Possible Interactions or Cautions
Generally safe; immunocompromised individuals should consult a healthcare provider; rare cases of systemic infections reported in extremely vulnerable patients.
Final Thoughts
Lactobacillus plantarum is a robust probiotic offering broad-spectrum support for gut and immune health, making it an excellent choice for daily supplementation.
