Abstract

Objective: This study investigates the effects of fish oil supplementation on cardiovascular health markers, including blood pressure and lipid profile, in adults.

Context: Omega-3 fatty acids in fish oil are known for their potential benefits on heart health. However, the extent to which daily supplementation could influence cardiovascular risk factors remains to be fully elucidated.

Methods Used: A double-blind, placebo-controlled trial was conducted with 100 participants over a 6-month period. Participants were randomly assigned to receive either fish oil supplements (containing EPA and DHA) or a placebo. Blood pressure, cholesterol levels, and triglycerides were measured at baseline and at the end of the study period.

Researchers' Summary of Findings: Participants receiving fish oil supplements showed a significant reduction in systolic and diastolic blood pressure, as well as improved lipid profiles, characterized by increased HDL (high-density lipoprotein) and decreased LDL (low-density lipoprotein) and triglycerides, compared to the placebo group.

Health Implications: Daily supplementation with fish oil can positively affect cardiovascular health by improving blood pressure and lipid profiles. This suggests that fish oil could be a beneficial addition to the dietary regimen for individuals at risk of cardiovascular diseases.
