Taking Fish Oil Supplements ? Without Fishy Burps
Mayo Clinic Health Letter

ROCHESTER, Minn. ? Do fish oil supplements just seem too ... well ... fishy?

The February issue of Mayo Clinic Health Letter explains some health benefits of this diet supplement and ways to overcome the occasional fishy aftertaste.

Fish oil supplements are especially good for those who want the heart health benefits of omega-3 fatty acids but don't like to eat fish. Fish oil supplements often are prescribed for heart attack survivors; the supplements can help prevent future heart problems. They also are prescribed for people with high triglycerides, a type of fat in the blood.

Tips to avoid fishy aftertaste or burps include:

  • Swallow the capsule frozen. This slows the breakdown of fish oil in the stomach, often reducing fishy burps. The fish oil is still digested effectively.
  • Take the capsule at the beginning of a meal. Food traps the fish oil in the stomach, and mixing buffers the odor.
  • Try an "odorless" supplement. This type of coated capsule passes through the stomach and dissolves in the intestines.
  • Switch brands. A different brand may taste less fishy. For fish oil purists, some manufacturers make a pure omega-3 fatty acids product that doesn't taste fishy, although it is likely to cost more than standard products.

Our experience indicated the Costco Brand had the worst fishy aftertaste, whereas Sam's Club and CVS Brand were the best.

Small caveat with CVS capsules, they tend to stick to the daily medication dispenser on humid days.

What are your experiences with other brands?
Krill oil doesn't cause the fishy burp thing. Its high in phospholipids and better at reducing inflammation. Its also naturally high in antioxidants. If I wasn't so broke I'd try it...people swear by it.
