Hook, Line, & Sinker: Get to Know Your Fish Oil

When you first decide to supplement with fish oils to support your overall health, you may wonder: With so many product options available, how do I know what to look for?

Watch for Purity Testing

When selecting a fish oil supplement, know there are various forms of testing that can be done to ensure the source meets quality standards. You should feel confident that the fish oil you choose lives up to its purity and potency claims and has been extensively tested for contaminants that are potentially harmful. Here’s what you need to know.

Something’s Fishy

Don’t settle for a lesser fish oil. Seek out a reputable supplement company that conducts potency testing in addition to testing for the following contaminants and toxins.

  • Potency: Testing to verify fatty acid content matches what is listed on the label—EPA, DHA, and other omega fatty acids such as omega-6s.
  • Rancidity potential (oxidative measures): Testing to ensure freshness has not been compromised by exposure to air, heat, light, and metals during manufacture, which can affect taste and smell.
    • Peroxides
    • Anisidine
    • TOTOX
  • Environmental contaminants & heavy metals: Purity testing for the presence of environmental toxins and industrial chemicals.
    • Dioxins & furans
    • Polychlorinated biphenols (PCBs)
    • Dioxin-like PCBs
    • Heavy metals (lead, tin, cadmium, mercury, arsenic)
    • Other industrial metals (iron, copper)
    • Iodine 131

Reputable third-party laboratories offer reliable, analytical methods for characterizing the identity, purity, composition, and authenticity of fish oil formulas. Be sure to look for a quality guarantee with verified testing information that ensures the highest level of purity possible.

If you suspect a bad fish oil, remember: There are plenty of other fish in the sea!
