Research
editAs an antioxidant, tyrosol may protect cells against injury due to oxidation in vitro.[3] Although it is not as potent as other antioxidants present in olive oil (e.g., hydroxytyrosol), its higher concentration and good bioavailability indicate that it may have an important overall effect.[4]
Tyrosol may also be cardioprotective. Tyrosol-treated animals showed significant increase in the phosphorylation of Akt, eNOS, and FOXO3a.[5] In addition, tyrosol also induced the expression of the protein SIRT1 in the heart after myocardial infarction (MI) in a rat MI model.[6]
Tyrosol forms esters with a variety of organic acids.[7] For example, oleocanthal is the elenolic acid ester of tyrosol.
