This is where probiotic dietary supplements come into play. They are designed to replenish the gut with beneficial bacteria, promoting a healthier microbiome. Common strains found in these supplements include Lactobacillus, Bifidobacterium, and Saccharomyces boulardii. Each strain offers different health benefits; for instance, Lactobacillus can help alleviate symptoms of lactose intolerance and diarrhea, whereas Bifidobacterium may enhance immune responses and aid in the prevention of certain infections.
