How is the study designed?

Design Details

  • Primary Purpose: Basic Science
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Fish oil supplementation arm
Participants will receive Fish Oil
Dietary supplement: Fish Oil Supplementation

Enrolled participants will be instructed to start taking 2 capsules per day on the day they take their baseline O3I and once O3I results are available to adjust to a personalized dose of Fish Oil, based on their baseline Omega-3 Index, and instructed to continue their current omega-3 dietary intake. Recommendations will be:

  • O3I > 6.8% but ≤ 8% - 1 capsule
  • O3I > 5.5% but ≤ 6.8% - 2 capsules
  • O3I > 4.4% but ≤ 5.5% - 3 capsules
  • O3I ≤ 4.4% - 4 capsules
