Label Accuracy
Omega-3 fatty acid content was measured at 350mg/serving, 2.8% below its 360mg label claim.
However, this product does not disclose either EPA or DHA amounts (our rankings account for and penalize products that do not disclose active ingredient content). Our analysis recorded 200mg EPA and 100mg DHA in every serving.
Product Purity
Mercury content measured at 1 PPB (part per billion), below the 2.4 PPB category average. The Global Organization for EPA and DHA Omega-3 (GOED) mercury limit is 100 PPB. Bulk samples of this product also passed the six mineral assays, indicating presence of under 1 PPM of arsenic, lead, cadmium, bismuth, antimony, and silver.
Polychlorinated Biphenyl (PCB) content (representative of aroclors 1016, 1221, 1232, 1242, 1248, 1254, and 1260) measured at less than 0.01 PPM. The Food and Drug Administration's (FDA) 2 PPM limit on PCBs for the edible parts of fish/shellfish. California’s Proposition 65 requires products containing greater than 0.09 PPM of PCB content to bear a cancer warning.
Peroxide value recorded at 11.4 meq/kg, and p-anisidine value recorded at 14.3.
Note: Our freshness scores are based entirely on peroxide values, measures of primary oxidation in fatty acids. Flavoring agents have been shown to skew p-anisidine values (measures of secondary oxidation). LabDoor is currently researching alternative p-anisidine assays that have the capability to account for and eliminate the effects of flavoring.
Nutritional Value
One serving of Puritan's Pride Premium Omega-3 Fish Oil provides 350mg total omega-3 fatty acids, below the 1.1g - 1.6g daily Adequate Intake (AI) range set by the Institute of Medicine (IOM) for individuals over the age of 14. Of the total omega-3 content, EPA accounts for 200mg and DHA accounts for 100mg. There is currently no established daily recommended intake for EPA and DHA, although the World Health Organization's (WHO) recommendation -- 0.3g - 0.5g EPA + DHA/day with 0.8g - 1.1g ALA/day (which is partially converted to EPA and DHA) -- is held in high regard.
Furthermore, this product consists of 25% EPA + DHA, below the 47% category average.
Ingredient Safety
Mercury content measured at 1 PPB, below the 2.4 PPB category average and significantly below the 100 PPB limit established by the Global Organization for EPA and DHA Omega-3 (GOED).
PCB content measured at less than 0.01 PPM, significantly below the 2 PPM limit set by the Food and Drug Administration (FDA) and the stricter 0.09 PPM limit enacted by California’s Proposition 65.
Projected Efficacy
Omega-3 fatty acids constitute 29% of this product's total fish oil content (Mean = 54%).
350mg of total omega-3 fatty acids, significantly below the 818.4mg category average, consisting of 200mg EPA (Mean = 473.3mg) and 100mg DHA (Mean = 243.1mg) is expected to be minimally effective based on an estimated 1g recommended daily intake.
Omega-3 fatty acids are clinically shown to improve cardiovascular conditions such as coronary heart disease, hyperlipidemia and hypertension, and, according to limited evidence, enhance cognition, reduce anxiety, improve athletic performance and decrease risk of certain cancers. Clinical research supporting the latter effects is promising, but not conclusive; additional research is required before any conclusions can be drawn.
