Lactobacillus gasseri is a probiotic bacteria that lives naturally in the human digestive and urinary tracts. Supplement makers include it in capsules and powders to support digestion and a healthy gut environment.
Many people take it to maintain a balanced gut microbiome. It has also been researched for its potential to help manage weight, especially by reducing abdominal fat, and to improve markers of metabolic health.
Dosage is typically a daily capsule or powder, taken with a meal to help the bacteria survive stomach acid. Different strains like BNR17 and CNCM I-5076 are available, and their effects may vary slightly.
At first, some users notice mild gas or bloating. People with severely weakened immune systems or critical illnesses should speak with a doctor before using it. Spacing probiotics a few hours apart from antibiotics can prevent interference.
