Fish oil vs Algae omega-3
For DHA, this one is settled: our catalog lists algae oil as bioequivalent to fish oil. The real differences are EPA content, contaminants, and whether you eat animal products.
Fish oil typically delivers more EPA per dose and costs less. Algae oil skips ocean contaminants entirely and is the only option for vegans.
| Attribute | Fish oil | Algae omega-3 |
|---|---|---|
| Best for | Higher EPA doses, triglyceride work, budget | Vegans, contaminant-free sourcing, DHA focus |
| Evidence | Strong for triglyceride lowering | Strong for DHA/EPA benefits; DHA bioequivalent to fish oil |
| Daily dose | 500-2,000 mg EPA+DHA | 250-1,000 mg |
| When | With a fat-containing meal | With a fat-containing meal; refrigerate |
| Watch for | Anticoagulant interaction; keep supplemental EPA+DHA at 2,000 mg or less without supervision | Often less EPA per dose; check the label |
Which one should you take?
Pick Fish oil if
your target is triglycerides or you want more EPA per dollar. That's where its strong evidence sits.
Pick Algae omega-3 if
you're vegan, cautious about contaminants, or simply want DHA without the ocean supply chain. Bioequivalence means you give up nothing on the DHA itself.
Can you take both?
Nothing dangerous happens, but the catalog's note applies: both provide EPA and DHA, so track the combined total. Keep supplemental EPA+DHA at or under 2,000 mg without supervision, and pick the single source that matches your diet instead of paying twice.
