What is Burpless Fish Oil?

If you’ve taken a fish oil supplement, you might be familiar with the gross “fish burp” side effect that accompanies some of these supplements. It can feel like you’re walking around the rest of the day after eating a fragrant seafood platter for breakfast.

To counteract this unwanted side effect, some fish oil manufacturers are now making their products with a “burp-free” or “burpless” formula. These formulas make a daily fish oil practice much more appealing, and in this article we’ll show how they work.

The Science Behind Burpless Fish Oil

How do manufacturers create a fish oil that doesn’t leave you with fish burps? There are three main ways:

  • Adding a special coating to their softgel capsules
  • Using molecular distillation to further purify their fish oil
  • Offering their product in a liquid format

Each of these methods can be effective in producing a burpless fish oil supplement.

Adding a Special Coating

Some fish oil supplements use a special coating on their softgels to prevent fish burps and aftertaste.

The reason this coating works to stop fish burps is that it protects the capsules from breaking down in your stomach acids. This allows them to reach your intestines, rather than dissolving in your stomach and rising up as fish burps.

Molecular Distillation

One common concern regarding fish oil is the presence of heavy metals, like mercury. Thankfully, reputable fish oil manufacturers put their oils through a purification process the helps remove harmful toxins like mercury and PCBs.

A few brands have figured out how to take this purification method to the next level, using it to eliminate fish burps. They pull this off through the process of molecular distillation which heavily purifies the oil resulting in an ultra-pure, burpless fish oil.

Softgel vs Liquid Fish Oil

Fish oil supplements typically come in a softgel format, but there are a few popular liquid fish oils like the award-winning Carlson Cod Liver Oil.

Most customers prefer the standard softgel capsules, and we agree that liquid fish oil takes some getting used to – in particular, the texture is a serious hurdle. That said, one benefit of liquid fish oil is that it goes down smoothly and is generally less prone to causing fish burps that standard fish oil capsules.

Impact on Health Benefits

The good news is that the transition to a “burpless” formula should have no impact on the nutritional contents or health benefits of your fish oil supplement.

Most fish oils are packed with omega fatty acids in both EPA and DHA forms. Studies have shown fish oils can improve brain, heart, and eye health.
