L. Paracasei is a strain of Lactobacillus paracasei built to survive stomach acid better than many standard probiotics. That toughness helps more of the bacteria reach the intestines alive. From there, it supports digestive balance and the body's immune function.
People often turn to this strain during or after a course of antibiotics to help repopulate beneficial gut bacteria. It also gets used for maintaining immune defenses during seasonal challenges.
Take L. Paracasei in a capsule or powder with a meal. Food helps buffer stomach acid and improves survival. The first few days of use can cause mild gas or bloating, though this typically passes.
