Which contains more EPA?

  1. Flax seed
  2. Salmon
  3. Lamb
  4. Algae

Answer: b. Salmon

Flax seed and algae are good vegetarian sources of omega-3s, but they contain significantly less EPA than salmon. For balanced EPA/DHA intake, fish oil is the most efficient supplement option. For vegans, algae is the most efficient source of both EPA and DHA.
