Optimal range: 0 - 603 mmol/mol creatinine
Microbes resident in the large intestine of the human body help to break down complex aromatic compounds in dietary plant matter (polyphenols), freeing up benzoic acid, which enters the bloodstream. The liver can add the amino acid glycine to benzoic acid to form hippuric acid, which re-enters the blood and is absorbed by the kidneys. As a result, the kidneys excrete hundreds of milligrams of hippuric acid into the urine every day.
