Study summary

This study evaluates effects of different doses of phenolic acids on healthy volunteers.

Read the detailed description

It has been suggested that consumption of food rich in phenolic acids can help to improve vascular health, measured by flow mediated dilation (FMD).

Inclusion criteria

  • Male or postmenopausal female healthy volunteers aged 45-65 years old
  • Willing and able to sign written informed consent prior to trial entry
  • Healthy as determined by the medical history and physical examination

Exclusion criteria

Exclusion Criteria:

What researchers measure

Primary outcomes

  1. Efficacy by oral administration of phenolic acid in improving endothelial function

    Average change from baseline in %FMD at any time point post treatment. Responses will be calculated as the percentage change in brachial artery diameter from baseline.

    Time frame: 6 hours

Secondary outcomes

  1. AUC(Area Under Curve) of the concentration/time curve

    link between endothelial function improvement in healthy subjects and plasma concentration of phenolic acids

    Time frame: 6 hours

  2. Tmax

    link between endothelial function improvement in healthy subjects and plasma concentration of phenolic acids

    Time frame: 6 hours

  3. Elimination half-life

    link between endothelial function improvement in healthy subjects and plasma concentration of phenolic acids

    Time frame: 6 hours

Other outcomes

  1. Blood concentrations in plasma.

    Blood concentrations in plasma.

    Time frame: 6 hours

  2. To investigate safety of investigational products: Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]

    Incidence of Treatment-Emergent Adverse Events \[Safety and Tolerability\]

    Time frame: through study completion, an average of 1 year.
