Primary Outcome Measures:
  • Change in C Reactive Protein (CRP) [ Time Frame: 24 hours post endotoxin administration, following each 8 week intervention ]

Secondary Outcome Measures:
  • Prostaglandin J3 [ Time Frame: 7 days post endotoxin challenge ]
    Changes in plasma levels of prostaglandin J3 resulting from omega-3 supplementation and induced inflammation
