Probiotics are microorganisms that help increase good bacteria in your gut. You can get probiotics in the form of food as well as supplements. They help strengthen your body against infection. They also have anti-inflammatory and antimicrobial properties.

They can also be directly added with the help of supplements. Postbiotic powder, pills, or liquid are some of the best postbiotics supplements.

Though these components have unique roles to play, they share some common benefits. Improved gut health is one of the major health benefits of pre, pro, and postbiotics.

  • Enzymes 
  • Cell wall fragments

How do postbiotics work

Scientists have yet to arrive at a consensus about how postbiotics work in the human body. One widely researched postbiotic butyric acid, a short-chain fatty acid present in the colon, determines the growth of bacteria in the stomach. So, one can control the number of bacteria in the gut by adding butyric acid to the stomach. A few of these bacteria are known to boost the immune response of the colon's lining. This immune response is significant given a large number of bacteria present in the colon. Research has opined that some good bacteria boost the immune system to stop bacteria from entering the bloodstream. [1] Efforts are still going on to know the role played by postbiotics in the human immune system.   

What are the benefits of the postbiotic?

Metabolism is different in every individual, so the benefits of postbiotics are also different. Doctors often give patients postbiotics as medicine which contain higher doses than the bacteria could produce. Some postbiotics need to be kept in refrigeration to function properly. Postbiotics offer various health benefits, some of which are as follows:

  • They may curb allergies

Recent research has said that postbiotics help control the severity of eczema, a type of skin disease, if given as supplements. [2]

  • They may help in weight reduction 

Postbiotics, for example, short-chain fatty acids, are said to suppress the hunger signals in the body and help people to eat in fewer amounts. This helps in the process of weight loss. 

  • They may cut down the risk of heart ailments 

Butyrate acid is known to control the blood pressure level and repress genes which are responsible for maintaining cholesterol levels in the body. 

  • They may help control blood sugar level 

Butyrate acid is known to help manage blood sugar in patients.

  • They may prevent tumors 

Some postbiotics are known to reduce the development and spread of some types of cancer cells, such as the stomach and colon. 

  • They may have better tolerance capacity than probiotics 

Probiotics fuel up the beneficial bacteria in the bodyHowever, they may not be digested well by everyone. So, if you are intolerant to probiotics, you can consume postbiotics.
