Analysis

The blend clearly supplies 400 mg EPA and 200 mg DHA, giving the marine component an EPA-forward profile. Evening primrose contributes 50 mg GLA, while flax adds 260 mg alpha-linolenic acid for broader fatty-acid coverage.

Those line-item amounts make the formula easier to judge than blends that list only total oil. The combined marine omega-3 amount suits daily maintenance, though it is below the larger servings generally chosen for more targeted lipid support.

Fish species are named, but the molecular form of the fish oil is not disclosed. No antioxidant stabilizer or independent contaminant testing is stated, and evening primrose provides only a modest GLA amount.

Who is it for
  • Adults wanting marine and plant fatty acids together
  • People seeking an EPA-forward maintenance formula
  • Users who value clearly listed active amounts
Best for
  • Cardiovascular maintenance
  • Broad fatty-acid coverage
  • General inflammatory-balance support

Pros

  • Clearly lists 400 mg EPA and 200 mg DHA
  • Adds GLA and alpha-linolenic acid
  • Names anchovy, mackerel, and sardine sources

Cons

  • Does not identify the fish-oil molecular form
  • Provides a modest rather than high marine dose
  • Does not state antioxidant or independent purity testing

Warnings

  • Avoid with a fish allergy because the blend contains marine oil
  • Evening primrose oil may be unsuitable for people with seizure disorders or medicines that lower seizure threshold
  • EPA and DHA may add to bleeding risk with anticoagulant or antiplatelet drugs

Nutrient quality

82 Highest impact

EPA anchors a broad, logically combined fish and plant oil formula. Unspecified molecular forms and modest DHA and GLA amounts reduce focused potency.

Ingredient transparency

83 Highest impact

Active fatty-acid amounts are clearly disclosed without a hidden blend. Complete use directions and inactive-ingredient details are not available.

Customer satisfaction

73 High impact

The aggregate satisfaction measure is favorable, with response volume determining how much confidence it deserves. Comment-level evidence is absent, so recurring complaints and purpose fit cannot be verified.

Value for money

76 High impact

Broad fatty-acid coverage and transparent doses support good value. Moderate potency and missing oil-form details keep the product from standing out.

Fish Oil · 1070 mg

Clearly disclosed EPA and DHA provide direct, evidence-based support for triglycerides and vascular inflammatory balance. ALA and GLA broaden the fatty-acid profile without obscuring the marine omega-3 amounts.

The EPA and DHA serving is useful but below the larger amounts commonly used for substantial triglyceride reduction. The focused oil blend is still one of the strongest cardiovascular fits in this group.

EPA and DHA provide the strongest direct anti-inflammatory mechanism, with evening primrose and flax oils adding other fatty-acid pathways. The combined marine omega-three amount suits maintenance but falls below a high-potency focused dose.

Individual EPA and DHA amounts are clear, while the fish-oil molecular form and oxidation protection are not disclosed. People with fish allergy should avoid the marine-oil component.

Report overview
D- Active Ingredient Quality & BioavailabilityC Dose, Safety & Label TransparencyB+ Value

The EPA amount is meaningful and clearly exceeds DHA, but the fish oil molecular form is not identified. EPA density is moderate, and no antioxidant protection is listed. Purification or recognized third-party contaminant testing is also not stated.

Fish Oil · 1070 mg OverallScore54
F Active Ingredient Quality & BioavailabilityC- Dose, Safety & Label TransparencyB+ Value

EPA and DHA are individually listed at a combined 600 mg, providing a maintenance dose. Active concentration is about 56% of the fish oil, while the molecular form is not disclosed and a pharmaceutical-grade claim supports general purity. Value is good, and the lack of an antioxidant stabilizer leaves oxidation protection uncertain.

Gamma Linolenic Acid · 50 mg OverallScore42
D Active Ingredient Quality & BioavailabilityD+ Dose, Safety & Label TransparencyF Value

Evening primrose provides a clearly stated GLA yield, though it is less concentrated than borage oil and the active amount is low. No extraction method or antioxidant stabilizer is identified, leaving oxidative protection uncertain. The cost per active amount is high despite a modest serving price.
