Two omega-3 sources doing the same job.

Fish oil and algae oil both deliver the same active omega-3 fats, EPA and DHA (algae is in fact the original source fish get theirs from), so taking both just overlaps and adds cost without extra benefit for most people.

What to do

Choose one: fish oil is cheaper and usually higher in EPA, while algae oil is the vegan, fish-free option and is gentler on burping. Compare on the EPA/DHA dose, not the capsule count.
