Why Your Blood Needs Omega-3 Fatty Acids (Know The Reasons)

Are you aware of the importance of omega-3 fatty acids for your body?.

Omega-3 fatty acids are an essential component of a healthy diet and are necessary for a range of bodily functions.

In this article, we will explore why your blood needs omega-3 fatty acids, the sources, and the potential health benefits of omega-3 fatty acids.

So, let’s dive in and learn more about why omega-3 fatty acids are so important for your overall health and wellbeing.

What are omega-3 fatty acids and what do they do?

Omega-3 fatty acids are polyunsaturated fats found in the foods we eat, including fish and flaxseed, and in supplements, such as fish oil.

The three main omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

ALA is found mainly in plant oils such as flaxseed, soybean, and canola oils. DHA and EPA are found in fish and other seafood.

ALA is an essential fatty acid, meaning that your body can’t make it, so you must get it from the foods and beverages you consume.

Your body can convert some ALA into EPA and then to DHA, but only in very small amounts. Therefore, getting EPA and DHA from foods is the only practical way to increase levels of these omega-3 fatty acids in your body.

Omega-3s are important components of the membranes that surround each cell in your body.

DHA levels are especially high in retina, brain, and sperm cells.

Omega-3 fatty acids also provide calories to give your body energy and have many functions in your heart, blood vessels, lungs, immune system, and endocrine system.

Functions of omega-3 fatty acids

Studies have shown that EPA and DHA are important for:

  • Cognitive function
  • Good eyesight
  • Fetal development
  • Lowering bad cholesterol in the blood
  • Immunity
  • Preventing cardiovascular diseases

Are omega-3 fatty acids good for your blood?

Heart health

The U.S. Dietary Guidelines Advisory Committee concluded that consumption of two servings of seafood per week, which provide an average of 250 mg per day of long chain n-3 fatty acids, reduces cardiac mortality from coronary heart disease in persons with and without heart disease.

Prevention of coronary heart

For healthy adults without heart disease, omega-3 fatty acids in the blood may reduce the risk of death from cardiac events. ALA also appears to have a protective effect for the heart.

Higher ALA intake reduces the risk of heart disease, especially in populations with low levels of fish consumption.

Lowering blood triglycerides

It is well established that omega-3 fatty acids from fish lower blood triglycerides. Triglycerides are fats in your blood; their presence in blood is normal.

High levels, however, may be a risk factor for heart disease, most especially in combination with high LDL cholesterol.

EPA and DHA lower triglycerides in your blood by decreasing your body’s ability to make triglycerides.


Hypertension is the diagnosis of high blood pressure; it is an
independent risk factor for heart

Studies show that a high level of supplementation with EPA and DHA in the blood slightly reduces high blood pressure.

Dietary and lifestyle changes as well as medications are effective at lowering blood pressure, omega-3 supplementation may have a limited role in managing hypertension.
