When it comes to managing cholesterol levels, dietary supplements are often part of the conversation. One of the most commonly discussed is fish oil. But the question remains: does fish oil lower cholesterol?
Understanding Cholesterol: The Good and The Bad
Before we delve into the role of fish oil in cholesterol management, it’s crucial to understand what cholesterol is. Cholesterol, a waxy substance found in your blood, is essential for building healthy cells. However, high levels of it can lead to health issues.
Fish Oil: What is it?
Fish oil is derived from the tissues of oily fish. It’s rich in omega-3 fatty acids, which are known for their health benefits. These include reducing inflammation and potentially improving heart health.
Fish Oil and Cholesterol
Fish oil contains two types of omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Both have been studied for their effects on cholesterol levels.

The Impact of Fish Oil on Cholesterol Levels
Research suggests that fish oil doesn’t necessarily lower overall cholesterol levels. However, it can alter the types and proportions of cholesterol in the body, which may be beneficial for heart health.
Fish Oil and Triglycerides
One of the most significant impacts of fish oil is on triglyceride levels. Triglycerides are a type of fat in the blood that, when elevated, can increase the risk of heart disease. Fish oil has been found to significantly lower triglyceride levels.
Fish Oil and LDL Cholesterol
Low-density lipoprotein (LDL) cholesterol, often referred to as “bad” cholesterol, can build up in the arteries and increase the risk of heart disease. Studies have shown mixed results on whether fish oil can lower LDL cholesterol.
Fish Oil and HDL Cholesterol
High-density lipoprotein (HDL) cholesterol, also known as “good” cholesterol, helps remove other forms of cholesterol from your bloodstream. Fish oil may slightly increase HDL cholesterol levels, but more research is needed to confirm this effect.
Final Thoughts
While fish oil may not directly lower total cholesterol levels, its effects on triglycerides and potentially on LDL and HDL cholesterol can contribute to heart health. As always, it’s essential to consult with a healthcare professional before starting any new supplement regimen.
