Definition
Examples
PrebioticNon-digestible substances utilized by microbiota and confer a benefit to the hostInulin
Lactulose
Fructooligosaccharides
Galactooligosaccharides
ProbioticLive microorganisms that provide a benefit to the hostBifidobacterium
Lactobacillus
SynbioticPrebiotics and probiotics taken together
PostbioticInanimate strains with or without their byproducts that provide a benefit to the hostHeat killed Akkermansia Mucinophila
Heat inactivated Lactobacillus paracasei
Heat-inactivated Bifidobacterium bifidum
Byproduct of the above inanimate strains: Butyrate and Proprionate
Table 2 The influence of prebiotics, probiotics, and postbiotics on metabolic syndrome
Category
Influence

PrebioticInulinDecrease Firmicutes to Bacteroidetes ratio[22] Improvement in Obesity
FructooligosaccharidesIncrease Bifidobacterium[26]Promotes gut health
Decrease expression of inflammatory cytokines
Improved Insulin sensitivity
Galactooligosaccharides Increase Akkermansia mucinophila. Increase in Prevotella[27]Intestinal barrier protection
Improved Insulin sensitivity
Decrease inflammation
ProbioticBifidobacteriumIncreasing Akkermansia mucinophila[56] Intestinal barrier protection
Improved Insulin sensitivity
Decrease inflammation
LactobacillusDecreasing Firmicutes to Bacteroidetes ratio[57] Improvement in Obesity
PostbioticHeat-killed Akkermansia mucinophilaImproves metabolic state in Obesity
Heat-inactivated Lactobacillus paracaseiReduces the risk of pharyngitis, laryngitis, and diarrhea
Heat-inactivated Bifidobacterium bifidumReduces symptoms of irritable bowel syndrome
Butyrate (SCFA produced by the inactive microbe)Increasing Lachnospiraceae[46] Protection against diabetes and cardio-vascular diseases
Increasing Proteobacteria[46]Increased gut mucus production
Decreasing Clostridiaceae[46]Increased gut barrier integrity
