What are the best sources of Omega-3 EPA and DHA?
A common question we get here at NaturalMeds is why we don't stock krill oil or flax seed oil - great sources of Omega-3 EPA and DHA, right? Well, not exactly. Let's look at the facts...
Lets start with vegetarian sources of omega-3 such as green leafy vegetables, flax seed, and chia. These sources contain ALA, which then converts to EPA and DHA in our body. The problem is, the conversion rate is limited and variable - so even if your body is working optimally to convert that ALA, you still only end up with a very small amount of DHA and EPA. In fact, you would probably need to take over 30 flax seed 1000 mg soft gels daily just to get the recommended dietary intake.
So what about krill? A marine based source of omega-3 means your body is receiving EPA and DHA directly with no need for conversion. However, krill only contains a small amount of EPA and DHA compared to fish oil - EPA and DHA is what our body requires and generally what the omega-3 studies are referencing in their recommendations. Furthermore, there is no scientific evidence that the DHA and EPA from krill is better absorbed by the body (regardless of what you may hear). In fact a study was done in 2013 that contradicts that claim:
Here is a comparison chart that provides a simple and easy way to compare the different sources of EPA and DHA:
As you can see, a high-quality, purified fish oil is the safest, most effective source of the omega-3 essential fatty acids EPA and DHA.
