Vegans have lower serum levels of EPA and DHA but maintain higher-than-expected EPA proportions due to the conversion of linolenic acid (LNA) from plant oils like rapeseed oil.
As a vegan, your EPA and DHA levels will likely be lower than those who eat fish. However, if you consume plant oils rich in alpha-linolenic acid (like rapeseed or flaxseed oil), your body converts some of this into EPA. This means your EPA levels may be higher than expected for a vegan, even without fish oil supplements.

The proportions of EPA (p<0.001) and docosahexaenoic acid (DHA) (p<0.001) were clearly lower in the vegans’ serum than in that of the non-vegetarians; however, the groups did not differ with regard to docosapentaenoic acid (DPA) (22:5 n-3). ... the observed proportion of EPA in the vegans was still higher than expected. These results support the view that linolenic acid (LNA) is converted to EPA in humans.
