Why is ALA from plant sources less ideal than dietary EPA/DHA?

Answer

The body must convert ALA inefficiently into EPA and DHA.

While plant-based sources like flaxseeds and walnuts do contain the omega-3 fatty acid alpha-linolenic acid (ALA), they are considered less effective for immediately boosting systemic EPA and DHA levels compared to consuming oily fish directly. The reason for this distinction is that the human body possesses enzymatic pathways that must convert the ALA into the longer-chain, biologically active forms, EPA and DHA. This conversion process is described as highly inefficient, meaning that relying solely on plant sources often fails to provide the required concentrations of EPA and DHA necessary for robust cardiovascular and neurological benefits, necessitating the inclusion of fish or supplements containing pre-formed EPA and DHA.
