Omega 3 and 6 Check (Essential Fatty Acids) Blood Test

About this test

As human diets have moved from that of hunter gatherer to the modern agricultural era, the amount of omega 6 fatty acids we consume has increased dramatically such that we now consume more than 10 times the amount of omega 6 as omega 3.

The resulting modern ratio of around 16:1 is believed to be responsible for a number of inflammatory diseases such as heart disease and type 2 diabetes. An ideal ratio is about 2:1 and this is normally achievable by changes in diet and supplementation of omega 3 rich fish oils or algae. This test checks the ratio of omega 6 to 3 and highlights any irregular levels.

Who is this test for?

This test is ideal for anyone wanting to know their omega 6 to omega 3 ratio. Especially useful for people monitoring type 2 diabetes or cardiovascular disease.

Tests Included

Essential Fatty Acids

Omega 6 and omega 3 are essential fatty acids in the body responsible for controlling inflammation, brain development and regulating blood pressure. Omega 6 has a pro-inflammatory role in the body while omega 3 has an anti-inflammatory role. To control inflammation, ideally your omega 6/3 ratio should be around 2:1.

A high ratio increases the risk of chronic inflammation in the body, which is thought to be involved in the development of heart disease, cancer and autoimmune diseases. Eating more oily fish, flaxseeds as well as taking a daily supplement of cod liver or algae oil are effective ways to increase omega 3 levels and lower your ratio.
