What do probiotics do?

Probiotics are live microorganisms that, when taken in adequate amounts, may support health—especially digestive and immune function. They are often called “good” or “friendly” bacteria because they can help maintain a balanced gut microbiome.

Digestive support

Probiotics may help support regularity, reduce occasional bloating or discomfort, and help maintain a healthy balance of gut bacteria after antibiotic use. Different strains have different effects; Lactobacillus and Bifidobacterium are among the most studied. CFU (colony-forming units) indicates the amount of live bacteria; typical doses range from billions of CFUs per serving.

Beyond the gut

Some research suggests links between gut health and immune function, mood, and skin, though evidence is still evolving. Probiotics are not a replacement for a balanced diet or medical treatment.

Choosing a product

Look for a product that states the strain(s), CFU count, and storage conditions. Quality and stability matter. This information is for education only; consult a healthcare provider before starting probiotics, especially if you are immunocompromised or seriously ill.
