Nordic Naturals named top cod liver oil for potency and taste
A new review ranks a specific brand highest for omega-3 content and flavor, while noting price and storage differences across the market.

Shoppers looking for cod liver oil have a new benchmark. Nordic Naturals Arctic Cod Liver Oil is rated the best option for its high potency and purity. The review notes that the orange flavor makes the supplement pleasant to consume.
The recommendation centers on nutrient density. A single teaspoon of the liquid product contains more than 1,000 milligrams of omega-3. It is made from wild-caught, sustainably sourced cod. The review points out that the product does not leave a fishy aftertaste. However, it carries a high price per ounce compared to other options.
Cod liver oil has a long history. Ancient Vikings and other Norse people consumed it during the winter months. Modern analysis confirms it is rich in vitamin D, vitamin A, and omega-3 fatty acids. These nutrients are often lacking in the modern Western diet.
The market offers two main formats. Liquid oils generally provide more omega-3, vitamin A, and vitamin D per serving than capsules. Liquids often require refrigeration after opening. Capsules do not need to be chilled, which makes them easier to store. Many manufacturers add flavors like mint, lemon, or orange to mask the taste of the liquid form.
Sustainability is a factor for some buyers. The review advises choosing products with certification from the Marine Stewardship Council or similar organizations. There is also a divide over fermented cod liver oil. Some manufacturers argue that fermentation preserves nutrients that distillation removes. Others contend that the process damages fatty acids and causes the oil to turn rancid faster. More studies are needed to resolve the debate.
Cost varies by format. Capsules range from 20 cents to $1 per serving. Liquids typically cost between 30 and 60 cents per serving. Liquid bottles often contain more total servings, which results in a higher upfront purchase price.
The review also identifies a top value pick. These kosher-certified capsules are free of wheat, gluten, soy, and other common allergens. They are packaged in the United States and tested for mercury, dioxins, and other contaminants. The large soft gels can be difficult for some people to swallow. A third option features a lemon flavor and carries an International Fish Oil Standards certification. It uses nitrogen flushing for freshness but includes some synthetic vitamins.
Consumers should note potential side effects. Most people experience only mild gastrointestinal symptoms like fishy burps or nausea. The oil can act as a blood thinner. People taking prescription blood thinners or those with high blood pressure should consult a doctor before use. It is not recommended for pregnant women and can interact with certain contraceptive medicines and weight-loss drugs containing orlistat.
