What are live microorganisms that provide health benefits to their host?

Probiotics are defined as live microorganisms, typically bacteria or yeast, that confer health benefits to the host when consumed in adequate amounts. They are often referred to as "good" or "friendly" bacteria because they help maintain a healthy balance of gut flora, support digestion, and can enhance the immune system. Probiotics contribute to overall health by preventing the growth of harmful bacteria, aiding in nutrient absorption, and sometimes even improving mental health through the gut-brain axis.

In terms of wellness and health, they are particularly recognized for their role in gut health, where they can help alleviate issues such as irritable bowel syndrome and diarrhea, and may also aid in certain inflammatory conditions. The effectiveness of probiotics is often strain-specific, meaning different strains of probiotics can provide different health benefits.

Antioxidants, vitamins, and minerals, while essential for health and wellbeing, do not fit the definition of live microorganisms. Antioxidants are compounds that help protect cells from damage by free radicals, vitamins are organic compounds necessary for normal metabolic functions, and minerals are inorganic elements crucial for various bodily functions. Therefore, probiotics stand out as the only option that directly describes live microorganisms with health benefits.
