Lactobacillus Acidophilus

  • Culture Enzymes Minerals & Vitamins

Lactobacillus acidophilus, thrives in acidic environments, such as the human gastrointestinal tract. It exhibits natural antibiotic resistance, protecting its beneficial properties. It played a pioneering role in yogurt production, promoting gut health and enhancing flavor.

Lactobacillus acidophilus is a probiotic bacterium which contributes to a healthy gut microbiota by producing lactic acid, creating an unfavorable environment for harmful bacteria. Consuming Lactobacillus acidophilus through foods like yogurt or supplements may have several benefits. It can improve digestive health, alleviate symptoms of disorders like diarrhea and IBS and enhance the immune system. This strain may also aid in lactose digestion for those with lactose intolerance. It is commonly found in fermented foods and available as supplements.

Emerging research on humans and animals suggest a potential link between Lactobacillus acidophilus and cognitive function. L. acidophilus, through neurotransmitter production and gut-brain axis communication, may impact mood, cognition, and memory.
