Postbiotics are the bioactive compounds the probiotic bacteria produce when they consume prebiotics (fiber). This term refers to the waste left behind after your body digests both prebiotics and probiotics.

There are various types of postbiotics (3Trusted Source):

  • short-chain fatty acids
  • lipopolysaccharides
  • exopolysaccharides
  • enzymes
  • cell wall fragments
  • bacterial lysates (a mixture made from bacterial components)
  • cell-free supernatants (a mixture of compounds produced by bacteria and yeast)
  • various other metabolites such as vitamins and amino acids

Health Benefits of Postbiotics

Although these bioactive compounds are considered the waste products of probiotic bacteria, they offer various health benefits to your body.

  • Boost Immune system
  • Help reduce Digestive Symptoms
  • Helps prevent and treat Diarrhea
  • May help reduce Allergies such as Atopic Dermatitis
  • Aids Weight Loss
  • Helps lower the risk of Heart Disease
  • Helps Manage Blood Sugar levels

Healthy postbiotics include nutrients such as vitamins B and K, amino acids, and substances called antimicrobial peptides that help to slow down the growth of harmful bacteria. Other postbiotic substances called short-chain fatty acids help healthy bacteria flourish.
