ALA sources such as flaxseeds, chia seeds, walnuts and their oils are good vegetarian options, although conversion of ALA to EPA/DHA is limited. If seafood is not consumed, an algae-based DHA/EPA supplement can also be considered as a vegetarian alternative.
The mentioned capsule provides 750 mg of EPA + DHA (450 mg EPA + 300 mg DHA), which is a relatively substantial supplemental dose for a 16-year-old and should not be taken routinely without professional guidance. Also, the “1250 mg fish oil” refers to the total oil, not the actual omega-3 content.
