Omega 3

Omega 3 are typically fatty acids. Unlike other fatty acids, these are known to be healthy for the body. Omega 3 is considered to be highly beneficial for heart patients or people with cardiovascular history. It can prevent inflammation and is an essential nutrient for regulating blood flow, building a strong immune system and maintaining cardiovascular health.

Omega 6: Omega 3

This is a ratio of Omega 6 to Omega 3 that helps to determine the overall level of inflammation in your body. Research studies have pointed out that Omega 3 and Omega 6 have opposite effects and therefore, a balance between the two is highly essential for a healthy immune system. Omega 3 is considered to have the effect of anticoagulant while Omega 6 is procoagulant. Omega 3 helps dilate blood vessels and Omega 6 is a vasoconstrictor.

The overall ratio of Omega 6 to Omega 3 will help you bring any changes to your diet for a balanced intake of fatty acids. The ideal ratio according to scientists is 2:1 although, people consuming highly processed foods may have a ratio as high as 10:1. 

Why take the test?

The Omega 3 blood test will help you identify if you have an Omega 3 or Omega 6 deficiency. The blood test is intended to help you understand if you have an optimum balance between Omega 6 and Omega 3. Most diets have enough amount of Omega 6 however, lack Omega 3. This is true especially if you are on a vegetarian or vegan diet and do not consume fish. This test is beneficial to those with type 2 diabetes and a cardiovascular history.

Additional Information

Omega-3 fatty acids are found in fish oil and certain plant oils, while omega-6 fatty acids are found in vegetable oils such as corn oil and soybean oil. Both omega-3 and omega-6 fatty acids are important for good health, but they need to be balanced in the diet.

Too much of one or the other can lead to health problems. For example, too much omega-6 can contribute to inflammation, while too much omega-3 can increase the risk of bleeding.

The Omega 3 and 6 (Essential Fatty Acids) blood test can help to determine if you are getting enough of these important fatty acids in your diet. It can also be used to check for certain medical conditions that may affect your levels of omega-3 or omega-6 fatty acids.

If you are considering an Omega 3 and 6 (Essential Fatty Acids) blood test, talk to your doctor about what the test is looking for and whether it is right for you.

Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert

Omega-3 and Omega-6 are essential fatty acids, acquired from eating certain foods, such as vegetables and nuts, chicken, certain fish and green leafy vegetables. 

Fats are important in improving brain health, immune systems, blood pressure regulation, and inflammation control, which can help the human body fight infection, among other vital roles.

Expert’s Opinion

Experts Opinion on Omega Home Tests

"Ideally, there should be a suitable ratio of omega 6 to omega 3. Inflammatory diseases can sometimes result from an abnormal balance of these essential fatty acids. 

This blood test can help you get a picture of your ratio and optimise your levels if necessary with diet or supplements."
