Frequently Asked Questions About Fish Oil (DHA)
What is fish oil (DHA) good for?
Fish oil (DHA) provides DHA, an omega-3 fatty acid found in the brain and eyes. DHA is important for normal brain and eye function, but taking a supplement does not mean it treats or prevents a disease.
What is the difference between DHA and EPA in fish oil (DHA)?
DHA and EPA are two different omega-3 fatty acids in fish oil (DHA) products. DHA is a major structural fat in the brain and retina, while EPA is a separate fatty acid; products can contain different amounts of each.
Should fish oil (DHA) be taken with food?
Fish oil (DHA) can be taken with food, which may reduce fishy burps or stomach discomfort. Follow the product directions, especially for liquid oils or capsules that specify a particular way to take them.
Can you take fish oil (DHA) every day?
Yes, fish oil (DHA) can be taken daily according to its label directions. Count DHA from other supplements too, and do not assume that taking more than directed will provide extra benefits.
Does fish oil (DHA) cause fishy burps, and how can you prevent them?
Yes, fish oil (DHA) can cause fishy-tasting burps in some people. Taking it with a meal may help; if the oil smells sharply sour or tastes unusually rancid, do not use it.
Is fish oil (DHA) safe to take during pregnancy?
Fish oil (DHA) can be a source of DHA during pregnancy, but the product and dose matter. Ask your prenatal care provider before starting a supplement, and do not confuse standard fish oil with fish liver oil.
Does fish oil (DHA) thin your blood?
Fish oil (DHA) is not a blood thinner, though high supplemental amounts may affect blood clotting. If you take anticoagulant medication or have a procedure coming up, ask your healthcare provider before using it.
Is fish oil (DHA) the same as cod liver oil?
No, fish oil (DHA) is not the same as cod liver oil. Cod liver oil can also provide vitamins A and D, so taking it alongside other supplements containing those vitamins may result in excessive intake.
Does fish oil (DHA) need to be refrigerated?
Fish oil (DHA) does not always need refrigeration; storage instructions vary by product. Keep it tightly closed and away from heat and light, and refrigerate an opened liquid only if its label directs you to.
Can fish oil (DHA) replace eating fish?
No, fish oil (DHA) does not fully replace eating fish. It supplies DHA, but whole fish also provides protein and other nutrients, so a supplement is not nutritionally identical to a fish meal.

What is Fish Oil (DHA)?
Fish oil (DHA) is oil obtained from fish and contains DHA, an omega-3 fatty acid. It is usually sold as a liquid or in capsules, rather than eaten as a whole-food ingredient, and is taken as a supplement.
Its flavour and smell can be distinctly fishy, though they vary by product. Liquid versions are measured by spoon; capsules are swallowed with water, often alongside a meal. Nutritionally, it is almost entirely fat, with no protein or carbohydrates. It may suit people looking for a source of DHA who do not regularly eat fish. Follow the product’s serving directions, and avoid using fish oil for frying or other high-heat cooking.
