What is the difference between a probiotic and a prebiotic? Probiotics and a prebiotics are both related to gut health, but they have different functions and effects.

Probiotics are live microorganisms, typically bacteria, that are similar to the beneficial microorganisms found in the human gut. They are often called “good” or “helpful” bacteria because they help keep the gut microbiome in balance, and can provide a number of health benefits such as improving digestion, boosting the immune system, and reducing inflammation. Probiotics can be found in fermented foods such as yogurt and kefir, as well as in dietary supplements.

Prebiotics, on the other hand, are non-digestible carbohydrates that serve as food for the beneficial microorganisms in the gut, such as probiotics. They are found in foods such as fruits, vegetables, whole grains, and nuts. Prebiotics can increase the growth and activity of beneficial microorganisms in the gut, and also can improve gut health and boost immunity.

Probiotics and prebiotics work together to promote a healthy gut microbiome, and both are considered important for maintaining overall health and well-being.
