DOs are a type of bacteria that are beneficial for human health. They help maintain a balanced gut microbiome, which is essential for digestion and overall well-being. Consuming foods rich in DOs, such as yogurt and fermented products, can support a healthy immune system and improve nutrient absorption. In addition to dietary sources, DOs can also be taken as supplements. These probiotics can help restore gut flora after antibiotic use or during digestive issues. It's important to choose high-quality products and consult with a healthcare professional before starting any new supplement regimen.
