Brief summary
This study will investigate the effect of Spanish Black Radish on phase I and phase II enzyme activity in healthy adult males. The primary objective is to determine the effect on phase I and phase II enzyme activity by measuring plasma and urine acetaminophen metabolite concentrations prior to and after a 28 day supplementation period with Spanish black radish product.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effect on Phase I and II enzymes | 4 weeks | The effect on phase I and phase II enzyme activity determined by measuring plasma and urine acetaminophen metabolite concentrations Subjects will ingest 1000 mg of acetaminophen. Blood will be collected at 0, 2, 4, 6 and 8 hours after acetaminophen dosage for the analysis of plasma acetaminophen metabolites. These measurements will be performed prior to and after 4 weeks of treatment with Spanish Black Radish product. |
Secondary
