#Omega-3 & Fish Oil
EPA, DHA, fish oil vs algal sources, paediatric doses and safety. Evidence-backed guide aligned with EFSA and AAP guidance.
Omega-3 is shorthand for a family of polyunsaturated fatty acids dominated by EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). EPA is associated with cardiovascular and anti-inflammatory effects; DHA is the structural fatty acid of the brain and retina. ALA (alpha-linolenic acid, from flax and chia) is plant-based but converts poorly to EPA/DHA in humans.
Sources. Most commercial supplements are sourced from cold-water fish (sardines, anchovies, mackerel) or — for vegetarians and those with fish allergies — from algae. Look for IFOS, GOED, USP or NSF third-party purity certification.
Doses. EFSA suggests 250 mg combined EPA+DHA daily as the adult population reference; therapeutic doses in trials span 1-3 g/day for cardiovascular and triglyceride benefit. Paediatric reference values per EFSA: 100 mg DHA from infancy through age 24 months; 250 mg EPA+DHA from age 2 onwards.
Safety. Generally well-tolerated. The most common side effect is fishy aftertaste, reduced by enteric-coated capsules or refrigeration. Discuss with a clinician before use if you take anticoagulants (warfarin, DOACs); high doses prolong bleeding time. A 7-14 day washout before surgery is standard.
On HealthyHerbology we cover omega-3 across women's beauty/cognition/prenatal angles, men's heart and recovery support, and paediatric brain-development guidance.

Frequently asked about Omega-3 & Fish Oil
- What is the difference between EPA and DHA?
- EPA (eicosapentaenoic acid) is most associated with cardiovascular and anti-inflammatory effects. DHA (docosahexaenoic acid) is the structural fatty acid of the brain and retina. Most evidence-based products contain both.
- Is fish oil safe for children?
- Pure, low-mercury algal or fish-derived omega-3 products are widely considered safe for children when dosed per EFSA paediatric reference values. Always consult your paediatrician first and choose third-party tested brands.
- How much omega-3 should I take daily?
- EFSA suggests 250 mg combined EPA+DHA for adults as a baseline; therapeutic ranges in studies span 1-3 g/day. Always discuss higher doses with a clinician, especially if you take anticoagulants.
