Probiotics are live microorganisms, primarily bacteria and yeasts, that provide health benefits when consumed in adequate amounts. They are often referred to as "good" or "friendly" bacteria because they help maintain a healthy balance in the gut microbiome, which is the community of microorganisms living in the digestive tract. Probiotics are naturally present in fermented foods and can also be taken as dietary supplements.

The most common probiotic strains belong to the genera *Lactobacillus* and *Bifidobacterium*, though other types, such as *Saccharomyces boulardii* (a yeast), may also be used. These microorganisms play a role in digestion, immune function, and the production of certain vitamins. They help break down food, absorb nutrients, and compete with harmful bacteria, reducing the risk of infections and inflammation.

Probiotics are commonly found in fermented foods like yogurt, kefir, sauerkraut, kimchi, and miso. They are also available in supplement form, often as capsules, tablets, or powders. The effectiveness of probiotics can vary depending on the strain, dosage, and individual health conditions. Some studies suggest benefits for digestive health, such as treating diarrhea (including antibiotic-associated diarrhea), irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD). They may also support immune function, reduce allergies, and improve mental health by influencing gut-brain communication.

While probiotics are generally considered safe for most people, side effects like bloating, gas, or mild stomach discomfort may occur, particularly when first introducing them. Those with weakened immune systems or severe illnesses should consult a healthcare provider before using probiotics. Research on their long-term effects and optimal strains for specific conditions is ongoing, making it important to stay informed about current evidence.
