Frequently Asked Questions
Do I need both EPA and DHA?
EPA and DHA play complementary roles: DHA supports brain and retinal structure while EPA is often linked to cardiovascular and inflammatory responses. For general heart and brain health, look for products that supply both EPA + DHA.
Are algae-based omega-3s as effective as fish oil?
Algae-based supplements provide DHA and sometimes EPA directly and are an effective, vegan-friendly alternative to fish oil. Check the label for the combined EPA+DHA dose to compare with fish-derived products.
How can I avoid fishy burps or aftertaste?
Choose flavored liquids or enteric-coated capsules, take supplements with meals, store liquids refrigerated, and look for products that note antioxidant flushing or special packaging to reduce oxidation and taste issues.
