  • Any treatment that included radiation or chemotherapy within the previous 2 years
  • Receiving/prescribed coumandin (Warfarin), heparin, daltaparin, enoxaparin or other anticoagulation therapy.
  • Regular use of supplements containing the investigational material (e.g. Omega-3 fatty acids), in the last 3 months, regular consumption of foods containing the investigational material (e.g. fish for omega-3) #
  • Active smokers, nicotine, alcohol, drug abuse
  • Chronic past and/or current alcohol use (>14 alcoholic drinks week)
  • Allergic to any of the ingredients (i.e., fish oil)

A serious illness is a condition that carries a risk of mortality, negatively impacts quality of life and daily function and/or is burdensome in symptoms and/or treatments.

      • Regular use or consumption is considered if participants are consuming omega containing supplements or foods on 3 or more days per week.
