Lactobacillus fermentum NBRC 3071

Lactobacillus fermentum is a species of probiotic bacteria found throughout the human oral and digestive tract. It also occurs naturally in fermented milk products and vegetable products.

The effectiveness of Lactobacillus fermentum bacteria in enhancing immune function and promoting upper respiratory and gastrointestinal health is well-documented, providing a reassuring testament to its health benefits.

L. fermentum strains have also been shown to produce a diverse range of potent antimicrobial peptides (AMPs). These compounds are natural antibiotics that rebalance the microbiome in the intestinal tract. Because they control the growth of bacteria that can cause spoilage, antimicrobial peptides also play an essential role in food preservation.

Like other species of Lactobacillus bacteria, L. fermentum ferments dietary fibers to produce short-chain fatty acids, including propionic, acetic, and butyric acids. These weakly acidic compounds are essential to gut microbiome ecosystem regulators and inhibit harmful bacteria growth.

Prolonged episodes of intense exercise are known to weaken the immune system. In a study with elite athletes (long-distance runners and competitive cyclists), L. fermentum bacteria significantly supported upper respiratory health after prolonged intense exercise.i,ii

With its wide range of health benefits, Lactobacillus fermentum is a versatile tool commonly used in food preservation, commercial probiotic formulations, and even infant formulas, instilling confidence in its diverse applications.
