Brief Summary
Omega-3 fatty acids are a certain kind of fish fat that has recently been shown to have health benefits. This study will examine the effectiveness of fish oil supplementation for reducing the early signs of heart disease risk and for improving mood, impulsivity, and anger levels.

Outcome Measures
Primary Outcomes (15)
Circulating Serum Interleukin-6 (IL-6)
Systemic inflammation: fasting serum Interleukin-6 (IL-6)
Baseline and Month 4
C-reactive Protein (CRP)
fasting serum C-reactive protein (CRP) in milligrams per liter (mg/L)
baseline and month 4
Negative Affect
Negative affect questions adapted from the Positive and Negative Affect Schedule - Expanded Form administered via ecological momentary assessment. The minimum value is 1, and the maximum value is 6. A higher score are worse (more negative affect).
baseline and month 4
Impulsivity
Barratt Impulsiveness Scale. The minimum value is 34, and the maximum value is 120. A higher score suggests a worse outcome.
baseline and month 4
Aggression
Bus-Perry Aggression Questionnaire. The minimum value is 14, and the maximum value is 53. A higher score suggests a worse outcome.
baseline and month 4
Hostility, Barefoot Score
The 27-item Barefoot Hostility Scale. The minimum value is 1, and the maximum value is 30. A higher score suggests a worse outcome.
baseline and month 4
Trait Anger
State-Trait Anger Expression Inventory. The minimum value is 10, and the maximum value is 40. A higher score suggests a worse outcome.
baseline and month 4
Anger Expression
State-Trait Anger Expression Inventory. The minimum value is 0, and the maximum value is 72. A higher score suggests a worse outcome.
baseline and month 4
Type A, Total Score
Structured Interview - Type A Behavior Pattern using the Interpersonal Hostility Assessment Technique (IHAT). The minimum value is 0, and the maximum value is 12. A higher score suggests a worse outcome.
