How to Choose
When selecting a cod liver oil, start by checking the EPA and DHA concentrations-higher levels mean more anti‑inflammatory benefits. Purity is equally important; look for products certified by IFOS, USP, or a reputable third‑party lab, and verify that they are free from heavy metals, PCBs, and dioxins. The form (softgel vs. liquid) should match your lifestyle: softgels offer precise dosing and convenience, while liquids can be mixed into foods for those who dislike swallowing pills.
Flavor and sustainability are additional factors. A mild or flavored product reduces the risk of fishy aftertaste, and sustainably sourced cod helps protect marine ecosystems. Finally, compare price per serving; a slightly higher upfront cost may be justified by better absorption, higher potency, or stronger purity guarantees.
