  • For over 50 years, hippuric/quinic acids were believed to have no biological efficacy. Here data are presented to support the hypothesis that quinic acid is not responsible for any efficacy, but rather that quinic acid nutritionally supports the synthesis of tryptophan and nicotinamide in the gastrointestinal (GI) tract, and that this in turn leads to DNA repair enhancement and NF‐kB inhibition via increased nicotinamide and tryptophan production.
