Lacticaseibacillus rhamnosus (L. rhamnosus), formerly known as Lactobacillus rhamnosus, is a well-known and widely used probiotic bacterium, found not only in many dietary supplements but also in fermented foods. It is particularly valued for its potential health-promoting properties that can positively affect the immune system and digestive tract. Some studies have indicated that L. rhamnosus may help prevent diarrheal diseases in children, modulate allergic reactions, and overall strengthen the immune system.
Regarding the metabolic capacity of this bacterium, L. rhamnosus is characterized by a remarkable versatility. As a facultatively heterofermentative bacterium, it has the ability to metabolize a wide range of carbohydrates, including simple sugars, certain oligosaccharides, mannose, and lactose. During this metabolic process, the bacterium produces lactic acid, which acidifies the gut environment. This creates an environment that is unfavorable for many harmful pathogens, thus contributing to overall gut health.
Unlike Bifidobacterium species, L. rhamnosus does not tend to establish itself permanently in the gut of infants. This means, although it can be beneficial for acute use, its effect in the gut is often only temporary and requires regular intake. Furthermore, scientific investigations confirm that certain strains of L. rhamnosus, such as those in Ventra Baby Drops, are capable of reducing the frequency of crying and restlessness in infants with colic, thus playing a valuable supportive role in the nutrition of these infants.
