Lactobacillus are a variety of gram-positive and anaerobic bacteria found in the gut. Lactobacillus casei can be found in the intestinal microbiota, while lactobacillus reuteri is used as a Probiotic supplement. They can perform various functions in the body, such as aiding Digestion, improving the immune response, increasing the Absorption of lactose by the body, among others.
The immune system is made up of cells, tissues and organs that act in the organism’s defense against the harmful effects of external microorganisms. The supplements indicated for immunity act as strengthening agents of this system, increasing the antibodies production and, consequently, its defense activity.
Probiotic supplementation stimulates the immune system by increasing antibody levels and increasing macrophage activity. They also contribute to the recomposition of the intestinal microbiota through adhesion and colonization of the intestinal mucosa, an action that prevents attachment and subsequent production of toxins or invasion of epithelial cells by pathogenic bacteria. Probiotics compete with undesirable bacteria for nutrients available in the organism.
