Top Fish Oil Brands and Factors to Consider
Choosing a high-quality fish oil supplement can be challenging. The best brands are committed to quality, transparency, and sustainability. Key indicators of a superior product include third-party certifications, high concentrations of EPA and DHA, and a bioavailable molecular form, such as natural triglycerides. Certificates of Analysis (COAs) from reputable brands detail the product's purity and potency.

How to Choose the Best Fish Oil Supplement
Read the Label Carefully
Focus on the combined milligrams of EPA and DHA listed in the 'Supplement Facts' panel. A quality supplement should provide at least 500–1000 mg of combined EPA and DHA per serving.
Prioritize Third-Party Testing
Because the FDA does not regulate supplements for quality, independent verification is essential. Look for certification seals from organizations like the International Fish Oil Standards (IFOS), NSF International, or the U.S. Pharmacopeia (USP) to ensure the product is free from contaminants like mercury, PCBs, and dioxins.
Consider the Molecular Form
Fish oil is most bioavailable in its natural triglyceride (TG) form. Many concentrated fish oils are processed into ethyl esters (EE), which are less efficiently absorbed by the body. Some manufacturers re-esterify the oil back into a triglyceride form for better absorption. Look for the 'TG' or 're-esterified triglyceride' form on the label.
Assess Freshness
Rancid fish oil not only tastes bad but can also be harmful. Smell the oil; it should have a very mild, fresh, sea-like scent, not a strong, fishy one. Look for products with added antioxidants like Vitamin E or rosemary extract to protect against oxidation.
The Importance of Sustainability
Responsible sourcing is a sign of a high-quality product. Look for certifications like Friend of the Sea (FOS) or the Marine Stewardship Council (MSC), which indicate that the fish were caught sustainably. Sourcing from smaller fish, such as anchovies and sardines, is also preferable, as they are lower on the food chain and have fewer accumulated toxins.
