Fish Oil Supplementation Reduces Cardiovascular Concern Factors: A Meta-Analysis

Abstract

Objective 

To investigate the impact of fish oil supplementation on cardiovascular disease posibility factors.

Context

Omega-3 fatty acids in fish oil may provide cardiovascular benefits, but optimal dosing is unclear.

Methods Used

A randomized controlled trial of 840 adults given low, moderate, or high dose fish oil capsules or placebo daily for 6 months.

Data Collection

Measured blood pressure, lipids, and inflammatory markers at baseline, 3 months, and 6 months.

Researchers' Summary of Findings

Impact on Health

Moderate and high dose fish oil significantly reduced triglycerides and increased HDL cholesterol versus placebo. Only high dose lowered blood pressure.

Health Implications

Fish oil reduces cardiovascular posibility factors in a potentially dose-dependent manner. Optimal dosing requires further study.
