What are probiotics? lactobacillus acidophilus Probiotics are living microorganisms that, when ingested, provide a health benefit (6). However, the scientific community often disagrees on what the benefits are, as well as which strains of bacteria are responsible (7). Probiotics are usually bacteria, but certain types of yeasts can also function as probiotics. There are also other microorganisms in the gut that are being studied, including viruses, fungi, archaea, and helminths (8). You can get probiotics from supplements, as well as from foods prepared by bacterial fermentation. Probiotic foods include yogurt, kefir, sauerkraut, tempeh, and kimchi. Probiotics should not be confused with prebiotics, which are carbs — often dietary fibers — that help feed the friendly bacteria already in your gut (9). Products that contain both prebiotics and probiotics are referred to as synbiotics. Synbiotic products usually combine friendly bacteria along with some food for the bacteria to eat (the prebiotics), all in one supplement (10Trusted Source). The most common probiotic bacteria are Lactobacillus and Bifidobacteria. Other common kinds are Saccharomyces, Streptococcus, Enterococcus, Escherichia, and Bacillus. Each genus comprises different species, and each species has many strains. On labels, you’ll see probiotics identified by their specific strain (which includes the genus), the species, subspecies if there is one, and a letter-number strain code Suggested use: Take 1 capsules daily with 1 glass of water 30 minutes before meal or as directed by physician Safety precautions: This product is not intended to cure any disease.
