What the AI looks for in DHA Nutritional Supplements
- DHA milligrams
- Check the DHA dose specifically; pregnancy guidance commonly cites at least 200 mg DHA a day. Generic fish oils are often EPA-heavy and deliver less DHA than buyers expect.
- Source
- Algal DHA is the fish-free option; fish-derived DHA should have published heavy-metal testing. Mercury concern is the main reason pregnant people choose supplements over eating fish.
- Freshness
- Same oxidation limits as fish oil, with GOED or IFOS-style testing. Oxidized DHA is common and unpleasant.
Brands that matter
- Nordic Naturals: Strong in prenatal, children's and algae DHA.
- Carlson: DHA- and EPA-specific concentrates.
What to avoid
- Doubling DHA when your prenatal vitamin already includes it, unless your clinician advises it.
- Gummy DHA with only token amounts per piece.
Questions
Is algae DHA as good as fish DHA?
Yes, DHA is the same molecule whatever the source; algae oil simply avoids fish.
