Prebiotic vs. Probiotic: Know the Difference

By Shumaila Saeed || Updated on December 25, 2023

Prebiotics are dietary fibers that feed beneficial gut bacteria, while probiotics are live beneficial bacteria themselves.

Prebiotic vs. Probiotic

Key Differences

Prebiotics are non-digestible food components, typically fibers, that promote the growth of beneficial microorganisms in the intestines. They act as food for probiotics. Probiotics, on the other hand, are live microorganisms, often found in yogurt, supplements, and fermented foods, that provide health benefits when consumed, primarily by improving or restoring the gut flora.

Nov 21, 2023

Prebiotics enhance the growth and activity of some beneficial bacteria in the gut. They are found in various fruits, vegetables, and whole grains. Unlike prebiotics, probiotics are sensitive to heat and stomach acid, which can reduce their effectiveness. Probiotics must survive the journey through the digestive system to be effective.

Nov 21, 2023

Prebiotics are stable and unaffected by temperature and body conditions. They reach the colon intact and are fermented by the beneficial bacteria present there. Probiotics require careful storage and handling to maintain their viability. They are often taken in supplement form or through certain fermented foods.

Nov 21, 2023

Prebiotics are beneficial for overall gut health and can help with issues like constipation and regular bowel movements. Probiotics can aid in specific gastrointestinal issues, like irritable bowel syndrome (IBS) and lactose intolerance, by introducing beneficial bacteria directly to the gut.

Nov 21, 2023

Prebiotics help in increasing calcium absorption, potentially enhancing bone density. Probiotics are known for their role in immune function, producing substances that can prevent the growth of harmful bacteria and viruses in the gut.
