What Are Probiotics?
In general, probiotics are living microorganisms, mostly bacteria or yeasts. They can provide the body with many health benefits when ingested. You could take probiotic supplements or fermented foods, such as kimchi, tempeh, sauerkraut, kefir, and yogurt. Keep in mind that probiotics are different from prebiotics, which are not microorganisms but dietary fibers that feed your gut. Common groups of probiotic bacteria include Bifidobacterium and Lactobacillus. Each group has various species and strains. [3]
