Increase your intake of EPA+DHA. The amount you would need to take in order to raise your Omega-3 Index into the target range (>8%) depends in part on your starting level, but it cannot be predicted with certainty as described above. Nevertheless, if your Omega-3 Index is between 4% and 8%, we would recommend that you increase your current EPA+DHA intake by 0.5 -1 gram (500 – 1000 mg) per day. This can be accomplished in two ways: eating more oily fish and/or taking fish oil supplements. On the other hand, if it is less than 4%, our recommendation would be that you raise your intake by 1-3 g (1000 – 3000 mg) per day. Although this can be accomplished by eating more oily fish, fish oil supplements are usually necessary to achieve this level of EPA+DHA intake.
In our experience, to increase the Omega-3 Index by 4%, one would need to increase his/her intake by about 1 g of EPA+DHA per day for roughly 6 months. Alternatively, one could increase by 2 g/d and a 4% increase could be achieved more quickly. In other words, raising the Index is a function of both dose and time.
