EPA and DHA are not the same line item
Fish oil may be listed by total oil weight while EPA and DHA appear as separate amounts. For comparison, record the EPA and DHA amounts per serving and the number of softgels needed to reach that serving.
- Do not compare total fish oil in one product with EPA+DHA in another.
- Check whether the source is fish, algae or another oil.
- Use the official label for the current serving and purity statements.
Food and supplements answer different questions
Fish can provide protein and other nutrients, while a supplement provides a more concentrated, predictable amount. FDA fish advice also asks consumers to consider species and mercury exposure, especially during pregnancy and childhood.
- Consider the whole diet before building a supplement stack.
- Keep fish species, serving frequency and life stage in view.
- Do not treat a purity badge as a substitute for reading the label.
Medication review is part of the label review
Omega-3 products can be relevant to bleeding risk, surgery and anticoagulant or antiplatelet medicines. Ask a professional about the total dose rather than relying on a generic “heart health” message.
- List all omega-3 sources before choosing a dose.
- Flag fish or sesame ingredients and excipients.
- Stop and seek advice for an allergic reaction or unusual bleeding.
