Lactobacillus reuteri is a probiotic bacterium found naturally in the human gut and in some fermented foods. People take it to help digestion and reduce occasional bloating or gas. Certain strains also support healthy cholesterol levels and oral health by helping keep H. Pylori in check.
Take this probiotic with a meal to protect it from stomach acid. You can get it as capsules, chewable tablets, or powders. Most people tolerate it well. If you have a weakened immune system or a serious illness, speak with a healthcare professional before starting any probiotic.
