Nature Made Cod Liver Oil does not disclose total omega-3, EPA, or DHA content (for which it was penalized on its Label Accuracy score). Our analysis recorded 130mg total omega-3, with 50mg EPA and 50mg DHA.
Mercury content measured at a category-high 6 PPB (parts per billion), greater than twice 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 3 meq/kg, and a p-anisidine value recorded at 18.5.
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.
A single serving of Nature Made Cod Liver Oil provides 130mg total omega-3 fatty acids, significantly 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 50mg and DHA accounts for 50mg. 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 19% EPA + DHA.
Mercury content measured at 6 PPB, over the 2.4 PPB category average but 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.
Omega-3 fatty acids constitute 24% of this product's total fish oil content.
130mg omega-3, consisting of 50mg EPA and 50mg DHA, is expected to be minimally effective based on an estimated 1g recommended daily intake. It is expected to be less effective than the majority of tested product containing larger amounts of omega-3 fatty acids and higher EPA+DHA content.
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.
