Buying Guide
Quick Care Guide: Make Liquid Fish Oil Easier to Take (and Keep Fresh)
Reduce burps with timing and temperature. Take liquid fish oil with a full meal that includes some fat, and keep the bottle chilled. For many people, cold oil tastes milder and is less likely to repeat on you later. If you are sensitive, start with a smaller amount for a few days and increase gradually.
Protect the oil from heat, light, and air. Close the cap quickly, wipe the bottle neck if it gets oily, and store it exactly as the label directs (often in the refrigerator after opening). Avoid leaving it out on a warm counter, and do not stash it by the stove. A fish oil can be “within date” and still taste off if it has been stored poorly.
Work it into food the right way. If you hate taking it straight, mix it into thicker, cold foods like yogurt, applesauce, or a smoothie. Skip hot coffee, oatmeal, or anything you microwave, since heat can amplify taste and may degrade delicate oils over time. Pick one consistent moment in your day, like after dinner, so it becomes automatic.

Frequently Asked Questions ▾
How do I choose a good liquid fish oil (and avoid a rancid one)?
Start with brands that clearly state purity testing and have strong quality controls. In real life, “good” usually means it tastes clean (often lemon or orange), has minimal aftertaste, and does not cause repeat fish burps. Once you open a bottle, oxidation risk goes up, so pick a size you can finish while it still tastes fresh, and store it exactly as directed, usually refrigerated. If the oil smells sharply fishy, paint-like, or bitter, stop using it and replace it.
How much liquid fish oil should I take per day?
Most adults choose a daily amount based on their combined EPA and DHA target, not just “fish oil” volume. If your main goal is general wellness, many people aim for a moderate daily intake and take it with a meal for better tolerance. If you are targeting triglycerides, inflammation support, or a clinician-directed plan, your needs may be higher and should be personalized. If you are pregnant, nursing, have a bleeding disorder, or take prescription blood thinners, confirm dosing with your clinician first.
Is liquid fish oil better than capsules?
Liquid is often easier if you dislike swallowing pills, want to adjust your serving size gradually, or prefer mixing it into food. It can also be a better value per serving, depending on the brand. Capsules can be more convenient for travel and may reduce taste exposure, which matters if you are sensitive to flavor. If you struggle with burps, a well-flavored liquid taken with a solid meal can be surprisingly comfortable, but some people still do better with capsules.
What is the best way to take liquid fish oil so it does not cause fishy burps?
Take it with a real meal, not just coffee or a piece of toast, and avoid taking it right before lying down. Chilling the bottle helps many people because cold oil tends to taste milder and can be easier on the stomach. If you are brand-new to fish oil, start with a smaller amount for a week, then work up, since tolerance often improves. Also avoid chasing it with carbonated drinks, which can increase reflux for some people.
Can I take fish oil with medications or before surgery?
Fish oil can interact with medications that affect bleeding risk, and some clinicians advise pausing omega-3 supplements before certain procedures. Do not guess if you take anticoagulants, antiplatelet drugs, high-dose NSAIDs, or if you have a scheduled surgery or dental procedure. Bring the bottle (or a photo of the label) to your appointment so your clinician can confirm whether to continue, adjust, or temporarily stop. If you have a fish allergy, choose extra caution and ask about alternatives such as algae-based omega-3s.
