What is the function of probiotics in gut health?

• A. To support a healthy gut microbiota and may improve digestion and immunity
• B. To increase blood pressure
• C. To decrease bone density
• D. To reduce respiratory rate

Answer: (A)

Probiotics help shape and maintain a healthy balance of gut bacteria. By introducing beneficial microbes, they support digestion—such as breaking down certain foods and producing compounds that nourish the gut lining—and can modulate the immune system to promote gut barrier function and overall gut health. Because of these effects, their function in gut health is to support a healthy gut microbiota and may improve digestion and immunity. Other options describe unrelated bodily processes like blood pressure, bone density, or respiratory rate, which aren’t roles of probiotics.
