Fish oil is made from the body of oily fish, while cod liver oil comes from cod livers. Cod liver oil also contains vitamins A and D, so it is not interchangeable with ordinary fish oil.
There is no required time of day to take fish oil. Taking it with a meal is often easier on the stomach and may reduce fishy aftertaste; follow the product’s directions for the serving.
Yes, fish oil can cause fishy-tasting burps in some people. Taking it with food may help; a persistent strong rancid taste or smell is different and can indicate that the oil has spoiled.
It usually refers to the amount of fish oil in a serving, not necessarily the amount of omega-3. Check the label for the separate EPA and DHA amounts, which can be much lower than the total oil amount.
Yes, fish oil can go rancid over time, especially when exposed to heat, light, or air. Follow the expiry date and discard it if the oil develops a sharp, rancid smell or an unusually unpleasant taste.
Keep liquid fish oil tightly closed and away from heat and direct light. Many liquid products need refrigeration after opening, so follow the specific storage instructions on the bottle rather than assuming all products are stored the same way.
Fish oil is not a good choice for frying or other high-heat cooking. Heat and air can damage its delicate fats; use a cooking oil intended for heat instead, and take fish oil as directed on its packaging.
It can be taken on an empty stomach, but some people find that this causes nausea or fishy burps. Taking fish oil with a meal is usually more comfortable and can make it easier to remember.
Some pregnancy supplements contain DHA from fish oil, but not every fish-oil product is suitable. Ask your prenatal care provider before starting one, and do not confuse fish oil with cod liver oil, which can contain substantial vitamin A.
Freezing fish oil is usually unnecessary and is not a substitute for following its storage instructions. Keep it sealed and away from heat and light; refrigerate liquid fish oil after opening if the label directs you to.

Fish oil (Omega 3, 2500 mg) is an oil obtained from fish, commonly sold as a dietary supplement rather than used as a cooking oil. It supplies omega-3 fatty acids, including EPA and DHA, and comes in liquid or capsule form.
People in many countries take it with a meal, while it is not usually served as part of a dish. Its taste can be distinctly fishy, especially in liquid form. Nutritionally, it is almost entirely fat: 100 g provides 900 kcal, with no protein or carbohydrate listed. Follow the serving and storage directions on the product label; capsules can be a convenient choice if you would rather avoid the taste.
Medium
How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Low
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
