Frequently Asked Questions About Fish and krill oil
What are fish and krill oil good for?
Fish and krill oil provide the omega-3 fats EPA and DHA, which support normal heart function. The amount of EPA and DHA varies by product, so the supplement’s effect depends on its actual contents.
Is fish oil or krill oil better?
Neither is best for everyone. Fish oil often provides more EPA and DHA per serving, while krill oil contains omega-3s alongside phospholipids and naturally occurring astaxanthin; compare the EPA and DHA amounts on the products.
Should you take fish and krill oil with food?
Yes, taking fish and krill oil with a meal is often easier on the stomach. A meal may also reduce fishy burps, especially when the supplement is taken with a substantial meal rather than on an empty stomach.
How much fish and krill oil should you take each day?
There is no single daily amount of fish and krill oil that suits everyone. Check the EPA and DHA per serving, not just the total oil weight, and do not take high-dose supplements without advice from a healthcare professional.
Can fish and krill oil cause fishy burps?
Yes, fish and krill oil can cause fishy-tasting burps or aftertaste. Taking the supplement with food, trying an enteric-coated product, or keeping it properly chilled when the label allows may help.
Can fish and krill oil be taken with blood thinners?
Fish and krill oil may affect bleeding risk, particularly at high doses or alongside anticoagulant medicines. Ask the clinician who manages your medication before starting a supplement, and tell them the product’s EPA and DHA dose.
How can you tell if fish and krill oil has gone rancid?
Rancid fish and krill oil may develop a sharp, unpleasant smell or taste unlike its usual mild marine scent. Don’t use a product that smells spoiled, has changed noticeably, or is past its expiry date.
Can you cook with fish and krill oil?
No, fish and krill oil are not suitable for frying or other high-heat cooking. Heat can damage their delicate omega-3 fats; take them as supplements according to the package directions instead.
Does fish and krill oil lower cholesterol?
Fish and krill oil are not a dependable treatment for lowering cholesterol. Omega-3s can affect triglyceride levels, but they do not reliably lower LDL cholesterol; don’t replace prescribed cholesterol medicine with these supplements.
How should you store fish and krill oil after opening?
Store fish and krill oil tightly closed, away from heat and light. Follow the label if it says to refrigerate the product, and pay particular attention to its after-opening instructions for liquid oils.

What is Fish and krill oil?
Fish and krill oil combines oils obtained from fish and krill, small marine crustaceans. It is usually sold as a liquid or in capsules, and is generally taken as a supplement rather than used as an everyday cooking oil.
The flavour and smell vary by product; liquid versions may have a distinct marine taste. In many places, people take it with a meal and water, following the serving directions on the label rather than adding it to hot food. It is entirely fat and provides omega-3 fatty acids, so it is energy-dense despite a small serving. Check the ingredients and serving information when choosing a product, especially if you avoid seafood or prefer a less noticeable taste.
