Brief Summary
Background: \- Metabolism is what the body does to turn food into energy. Omega-3 fatty acids are substances found in foods such as cold-water fish and shellfish that are essential for good health. Researchers want to see the effect of two fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on metabolism. They may be beneficial to cardiovascular health. Objective: \- To understand the effects of EPA and DHA on metabolism. Eligibility: \- Healthy people ages 18 years or above with plasma triglyceride (a type of fat in the blood) levels of 100 mg/dL or higher Design:
- The study will last 20 to 24 weeks.
- Participants will have 4 visits to the NIH Clinical Center. These will include:
- Medical history
- Physical Fasting blood and urine tests
- CAVI tests: blood pressure is taken in the arms and legs, and the heart is monitored.
- Participants will take an EPA/DHA dietary supplement. They will take 4 gel capsules, 3 times a day, for 6 or 7 weeks. Then they will not take the capsules for 8 to 10 weeks (a wash-out period). They will then take the capsules again for 6 or 7 weeks.
- Participants will keep a food journal.

Outcome Measures
Primary Outcomes (1)
Plasma PCSK9 Levels at Baseline and End of 6 Week Intervention
Measure plasma proprotein convertase subtilisin/kexin type 9 (PCSK9) level, at baseline, after 6 weeks of Eicosapentaenoic acid (EPA) or Docosahexaenoic acid (DHA) fish oil supplementation.
baseline to 6 weeks of intervention
Secondary Outcomes (1)
Plasma Levels in Triglyceride, Cholesterol, and Lipoprotein From Baseline to 6 Weeks
Baseline to 6 weeks of intervention
Study Arms (2)
EPA-rich fish oil arm then DHA-rich fish oil arm
EXPERIMENTALSubjects randomized to the EPA-rich fish oil arm will take the equivalent to 3g of EPA /day (12 gel capsules/day) for 6 more or less 1 weeks and cross-over to the DHA-rich capsule arm
DHA-rich fish oil arm then EPA-rich fish oil arm
EXPERIMENTALSubjects randomized to the DHA-rich fish oil arm will take the equivalent to 3g of DHA /day (12 gel capsules/day) for 6 more or less 1 weeks and cross-over to the EPA-rich capsule arm
Interventions
4 gel capsules, 3 times/day for 6 weeks
4 gel capsules, 3 times/day for 6 weeks
