MyOmega FAQs

You can get omega-3 and DHA from your diet through various food sources of omega-3 and/or from supplements. Dietary omega-3 is predominantly found in fish and other seafood. Although omega-3 can be obtained from plant sources, they are mainly in the form of Alpha Linoleic Acid (ALA) and their conversion to DHA and EPA is low (ranging from 0.1 to 10%)* If you are worried about fishy odour, concerned about the presence of heavy metals in fish and other seafood or have dietary restrictions then omega-3 supplements are a great choice to help you to achieve optimal omega-3 and DHA levels. *Reference: Effeciency of conversion of ALA to long chain Omega-3 Fatty acids (DHA and EPA), link: https://pubmed.ncbi.nlm.nih.gov/11844977/


Omega-3 can be found in a variety of foods such as:

1. Fish and Seafood: A variety of fish and seafood are great sources of Omega-3s. Fish such as salmon, mackarel, tuna, herring and sardines are low in mercury and excellent choice. It is recommended to avoid fish that are known to have high amounts of mercury for example king mackerel, swordfish and big eye tuna. for a full list, you can refer to the FDA advice on fish.

2. Flax seeds, Chia seeds

3. Walnuts

4. Plant oils (flax, chia, canola)

5. Other fortified foods (eggs, yoghurt, milk, beverages)

No, the personalisation takes into account the omega-3 that you have been getting from your regular diet so you can continue to keep the same dietary habits. However, if you do make changes to your dietary habits over a prolonged period we recommend that you re-take the test to accurately reflect your omega-3 levels.


Congratulations for already taking omega-3s! If you are already taking omega-3 supplements and worried about switching to a personalised dose, you can speak to your healthcare professional for advice.

Testing can provide you an omega-3 dose that is personalised to your needs. Eating fish or taking omega-3 supplements does not always correlate with high omega-3 DHA levels. Many other factors may affect omega-3 status, which include but are not limited to genetics, BMI and stage of pregnancy. Therefore testing will give a true reflection of the status in blood and milk.


You can find out your omega-3 DHA levels by testing with the Pre&Postnatal DHA Tests suitable for the maternal stage you are in: pre-conception, pregnancy or breastfeeding. The testing can be done easily form the comfort of your home. One drop of blood or milk is all you need! Once you perform the test using the instructions, simply mail it back to our partner lab* with the return envelope and wait for your test results. This is a convenient, at-home test of omega-3 DHA levels (in blood or milk) using a single dried blood or milk spot.

High consumption of omega-3 rich foods or supplements do not guarantee optimal levels of omega-3 and DHA. Many other factors may affect omega-3 status, which include but are not limited to genetics, BMI and stage of pregnancy. Therefore testing will give a true reflection of the omega-3 DHA status in your blood or milk. Morever, recent studies show the importance of the right amount of DHA for infant growth and development.
You can take the Prenatal or Postnatal DHA test at any maternal stage (before conception, during pregnancy and while breastfeeding). For pregnancy, it is always better to take the test before 20 weeks of pregnancy. However, if you are beyond 20 weeks of pregnancy, you can still take the test to know your omega-3 levels but you will receive the standard dose recommended according to national health authorities. For your breastfeeding period, we recommend to take the test not sooner than 14 days after delivery to personalise the dose during lactation.

You can test your omega-3 levels as often as you prefer. Re-testing every 8-12 weeks will confirm that your omega-3 DHA levels have improved with your dietary / supplement changes and will help tailor your personalised doses.

Pregnancy: current scientific evidence supports a personalised dose recommendation based only on your first test of your omega-3 baseline value (<20 weeks of pregnancy)* and this dose will be continued throughout the pregnancy irrespective of future tests. However, if you would still like to re-test to confirm your actual omega-3 DHA levels in your blood, you can choose to take the test again, but your recommendation will not change.

Lactation: we recommend you re-test your levels every 8-12 weeks to ensure optimal breastmilk concentration of DHA and omega-3, since it is the sole source of DHA for your baby. After every test your recommendation will be optimised based on your actual level of omega-3 DHA in your breastmilk.

You should also repeat the testing if there is a change in your maternal status for example, if you started prior to conception and become pregnant or started the program during pregnancy and are now post-delivery/breastfeeding.
MyOmega omega-3 dose recommendation uses an unique ratio of DHA:EPA and additional data based on research to ensure optimal omega-3 levels at all maternal stages, prior to conception, during pregnancy and whilst breastfeeding. Note: The calculator of our lab partner OmegaQuant does the calculation on DHA levels without additional data, so the recommendation may have a different value.
