Lactobacillus salivarius is a beneficial bacterium that lives naturally in the human mouth and gut. Different strains such as LS01 and UCC118 provide distinct effects, but the species overall supports oral and digestive health.
People use L. Salivarius to promote fresh breath, maintain a balanced oral microbiome, and ease occasional bloating. Certain strains are also studied for their role in immune support.
Take it as a capsule or lozenge, typically with a meal to help it survive stomach acid. Daily amounts usually fall between 1 and 10 billion CFU. Follow the directions on your product because the right strain and dose depend on your goal.
Mild gas or bloating can show up when you first start. If you have a weakened immune system or a serious health condition, check with a healthcare professional before use.
