EFADuo® (Omega-3 and Omega-6 Complex)

Evidence Level
Limited
1 Clinical Trial
3 Documented Benefits
2/5 Evidence Score

EFADuo® supplies a balanced complex of essential fatty acids, including omega-3 EPA and DHA. The best-established benefit of EPA and DHA is lowering triglycerides. Broader claims for brain, skin, and inflammatory health are mechanistic and are not backed by trials cited here.

Studied Dose Commonly 1 to 3 g of combined EPA and DHA per day.
Active Compound Omega-3 fatty acids EPA and DHA, from fish, krill, or algae.

Benefits

Healthy triglycerides

Omega-3 fatty acids reliably lower triglycerides, one of the best-established benefits of EPA and DHA for heart health.

Supported by Trial 1

Brain and mood support

DHA is a major structural fat in the brain. Large omega-3 trials for cognition and mood exist but are mixed, and none are cited on this page, so treat this as a mechanistic rationale rather than a proven effect of this product.

Supported by Trial 1

Anti-inflammatory support

EPA and DHA are converted into signaling molecules involved in resolving inflammation. This is a mechanism; no human trial measuring an inflammatory outcome for this product is cited.

Mechanism of action

1

Membrane incorporation

EPA and DHA are built into cell membranes throughout the body, improving membrane function in the heart, brain, and eyes.

2

Eicosanoid balance

Omega-3s are converted into specialized signaling molecules (resolvins and prostaglandins) that help resolve inflammation.

Clinical trials

1
Omega-3 and Cardiovascular Health — Cochrane Review
PubMed

Cochrane systematic review of omega-3 fatty acids for prevention of cardiovascular disease. (Abdelhamid et al. 2020, Cochrane Database of Systematic Reviews)

Adults across many large trials.

Omega-3 supplementation reduced triglycerides; the review found only small effects on overall cardiovascular events, so expectations for heart-attack prevention should be modest.

Side effects and drug interactions

Common Potential side effects

Generally well-tolerated.
Fishy aftertaste, burping, or mild digestive upset can occur.
Take with meals and choose a quality, oxidation-tested oil.

Important Drug interactions

Anticoagulants and antiplatelets — high-dose omega-3 may increase bleeding risk; monitor.
Blood pressure medication — possible mild additive effect.
Tell your doctor before surgery if taking high doses.

Cochrane Database Syst Rev. 2020;3(3):CD003177..PubMedUsed to support: In 86 randomized trials (162,796 adults), increasing long-chain omega-3 (EPA and DHA) reliably lowered triglycerides by about 15% in a dose-dependent way (high-certainty), but had little or no effect on all-cause mortality (RR 0.97) or cardiovascular events (RR 0.96), both high-certainty. This is generic omega-3 evidence, not a trial of this branded complex.
