p-Cresol sulfate is a metabolite produced by intestinal bacteria through the breakdown of the amino acid tyrosine. It is primarily detoxified in the liver and excreted by the kidneys. Higher levels may indicate increased bacterial protein fermentation, impaired detoxification, or reduced renal clearance. Balanced levels suggest efficient gut microbial metabolism and normal liver–kidney function.
High levels may indicate increased bacterial protein fermentation, impaired liver detoxification, or reduced kidney clearance. Raised p-Cresol sulfate is often observed in cases of gut dysbiosis or when liver–kidney detoxification pathways are under strain.
Testing can be beneficial for individuals experiencing chronic fatigue, digestive imbalances, or suspected detoxification problems. It may also assist those with impaired kidney function, liver overload, or indications of microbial imbalance in the gut.
Levels depend on gut microbial composition, protein intake, and the body’s ability to conjugate and excrete metabolites via the liver and kidneys. Diets high in animal protein or poor microbial diversity can increase production.
Yes. Supporting gut health through fibre intake, antioxidants, and probiotics can help reduce bacterial overproduction. Enhancing liver detoxification and maintaining hydration support the clearance of p-Cresol sulfate through natural elimination pathways.
