Product Overview
Lactobacillus johnsonii is a well-characterized probiotic widely present in the gastrointestinal tracts of humans and other hosts, including mice, dogs, poultry, pigs, and honeybees. This Gram-positive, rod-shaped, non-spore-forming bacterium is notable for its strong ability to adhere to intestinal epithelial cells, helping prevent colonization by harmful microorganisms.
The surface of L. johnsonii contains various proteins that enhance adhesion to the intestinal mucosa, thereby supporting gut barrier integrity and promoting a balanced microbiota. Traditionally used in fermented foods and feed, it has also been recognized for its potential across biology, agriculture, animal husbandry, and medicine.
Research highlights its multiple health benefits, including anti-inflammatory and immunomodulatory properties, gastrointestinal support, and reinforcement of intestinal barrier function. Its co-evolution with different hosts further suggests a strong link to long-term health effects.
