• Urinary metabolite of daidzein, produced by humans and horses.  Heinonen, S., et al.  "Identification of isoflavone metabolites dihydrodaidzein, dihydrogenistein, 6'-OH-O-dma, and cis-4-OH-equol in human urine by gas chromatography-mass spectrometry using authentic reference compounds."  Anal. Biochem. 274:  211-219 (1999).

• This product is a racemic mixture of the R- and S-enantiomers.  However, the naturally-occurring form of equol from horse urine consists of a single stereoisomer.  While the chemical properties of the single isomer form are essentially identical to those of the racemic mixture (except for rotation of plane polarized light, melting point, and so on), the biological properties of the single-isomer, naturally-occurring form are quite likely to be somewhat different from those of the racemic mixture.  In the future, LC Labs will be offering, at attractive prices, the pure single-isomer form of equol corresponding to the naturally-occuring urinary metabolite

• Sold for laboratory or manufacturing purposes only; not for human, veterinary, food, or household use.
