The Omega-3 Index measures the amount of Omega-3 fatty acids EPA and DHA as a
guide to your circulatory health. These same Omega-3 fatty acids have now also been found to keep your cells younger for longer.
With a level below 8% you might consider using a supplement. Omega-3 fatty acids occur naturally in oily fish, but unfortunately most people still do not eat the recommended two portions (of preferably oily fish) per week. Choose a supplement that supplies at least 500 mg to 1000 mg EPA+DHA per daily portion. EPA and DHA are the two main Omega-3 fatty acids. Also check the balance between Omega-3 and Omega-6.
We tend to consume far too many Omega-6 fatty acids from meat, dairy produce and vegetable oils such as safflower, sunflower, corn, sesame and groundnut oil.

Consuming less Omega-6 and more Omega-3 will enable you to achieve the optimum 5:1 to 2:1 balance and eliminate the 15:1 ratio, which is so often the result of the Western diet.
