Purpose
The objective of this study is to address the anti-thrombotic effects of tocotrienols supplementation via modulation of platelet activation, thrombotic markers, inflammatory markers and endothelial function.
It is hypothesized that 2 weeks supplementation of tocotrienols will be able to suppress platelet aggregation in subjects with metabolic syndrome.

Primary Outcome Measures:
- Platelet Aggregation [ Time Frame: Day 0 - fasting, Day 14 - fasting, Day 14 - 4hr ]Comparison will be made between Day 14-fasting and changes will be measured between Day 14-fasting and 4hr.
Secondary Outcome Measures:
- Platelet activation [ Time Frame: Day 0 - fasting, Day 14 - fasting, Day 14 - 4hr ]Comparison will be made between Day 14-fasting and changes will be measured between Day 14-fasting and 4hr.
- Haemostatic markers (Plasminogen activator inhibitor type 1 and sP-selectin) [ Time Frame: Day 0 - fasting, Day 14 - fasting, Day 14 - 2hr, Day 14 - 4hr, Day 14 - 6 hr ]Comparison will be made between Day 14-fasting and postprandial response will be compared between two interventions
- Inflammatory markers (sE-selectin, sICAM-1, and sVCAM-1) [ Time Frame: Day 0 - fasting, Day 14 - fasting, Day 14 - 4hr ]Comparison will be made between Day 14-fasting and postprandial response will be compared between two interventions
- Lipid Profile [ Time Frame: Day 0 - fasting, Day 14 - fasting ]Comparison will be made between Day 14-fasting
- D-dimer [ Time Frame: Day 0 - fasting, Day 14 - fasting, Day 14 - 4hr ]Comparison will be made between Day 14-fasting and postprandial response will be compared between two interventions
- Full blood count and liver function test [ Time Frame: Day 0-fasting and Day 14-fasting ]Comparison will be made between Day 14-fasting

Detailed Description:
A double-blind, randomized, crossover study comparing the effects of tocotrienols vs. placebo will be conducted in subjects with metabolic syndrome. Subjects will be supplemented with Tocovid Suprabio 200 mg twice daily (or placebo) for 2 weeks followed by a postprandial challenge on Day 14. During the postprandial challenge, venous blood samples will be collected during fasting. Subjects are then required to consume a high fat breakfast meal containing 50g fat and 100mL milkshake, followed by the assigned capsules. Venous blood samples will be drawn at 2, 4 and 6 hours after consumption of capsules. A washout period of at least 14 days will be in place before the commencement of the second treatment.
