Benefits for digestive and immune health

Saccharomyces boulardii helps maintain the balance of the intestinal microbiota, especially during periods of digestive stress. By contributing to the growth of beneficial flora, it supports normal digestive function and helps maintain stool consistency.* In addition, this probiotic stimulates the production of secretory IgA, a key antibody for the defense of the gastrointestinal tract, thus contributing to the normal functioning of the immune system.*

It is important to note that food supplements should not be used as a substitute for a balanced diet. This product is designed to complement a varied diet and a healthy lifestyle.

Ingredients and quality

Sacro-B contains Saccharomyces boulardii, a probiotic yeast strain with a long history of use in digestive health. Unlike many bacterial probiotics, Saccharomyces boulardii is resistant to gastric acids and bile salts, ensuring that it reaches the intestine alive. In addition, since it is not a bacterium, it is not affected by antibiotics, so it can be taken during antibiotic treatments to help maintain intestinal flora.
