Fishy Burps From Fish Oil? Why Some NZ Shoppers Switch to Krill Oil

You know the moment. You take a fish-oil capsule with breakfast or lunch, get on with your day, then an hour or two later that unmistakable fishy taste comes back.

At that point, the question is not whether omega-3 has a place in your day. It is whether you want to keep taking something that makes itself known for the rest of the morning or afternoon.

Fishy aftertaste, burping and digestive discomfort can happen with omega-3 supplements. If standard fish oil keeps making the experience unpleasant, changing omega-3 format is one option worth considering. Krill oil is not guaranteed to eliminate burping, but a well-tested low-odour product may be a better fit for some people.

When your fish oil keeps coming back

Fishy burps from fish oil can be annoying enough to turn a good intention into a supplement you keep skipping. Some people also notice an unpleasant taste, heartburn, nausea or other mild digestive discomfort with omega-3 supplements.

If you searched for fish oil burps NZ because this keeps happening to you, the main thing to know is that the experience can be real without telling you exactly why it is happening.

A fishy repeat does not tell you everything

A fishy taste or burp does not automatically prove that a fish oil is rancid. Freshness matters, but individual tolerance, the formulation and how a supplement sits with you can all affect the experience.

That is also why we would not diagnose fish oil reflux from a burp or aftertaste alone. If symptoms are persistent, painful or concerning, it is worth getting proper advice rather than trying to solve an ongoing digestive problem by swapping supplements repeatedly.

If timing is the main issue, start there

Sometimes the first question is simply whether taking an omega-3 with food, or at a different time of day, changes how it feels. We already cover that in detail in our guide on when to take krill oil with food, morning or night, including burps, reflux, nausea and digestive comfort.

We will not repeat all of that here. If meal timing is your main concern, that guide is the better place to start.

When changing omega-3 format starts to make sense

If you have tried standard fish oil more than once and keep disliking the taste or fish oil aftertaste, it is reasonable to consider a different marine omega-3 format.

That can be especially relevant when the experience is annoying enough that you stop taking the product consistently, even though you still want EPA and DHA from a marine source.

If your goal is fish oil without fishy burps, odourless fish-oil products also exist, so krill oil is not the only alternative. But if you are open to a different source and softgel format, we think Puraz 100% Krill Oil deserves a look because we have paid close attention to both what is in the oil and what it is like to take.

What actually changes with krill oil

Krill is a different marine source from standard fish oil, but it still provides the two familiar long-chain omega-3 fatty acids EPA and DHA. Krill oil also naturally contains phospholipids and astaxanthin.

Our current two-softgel serve provides:

• 1,000 mg krill oil
• 420 mg phospholipids
• 240 mg total omega-3 fatty acids
• 120 mg EPA
• 65 mg DHA
• 400 mcg naturally occurring astaxanthin

Those are useful differences to know, but they are not a promise that krill oil will never cause fishy burps. Published research has reported burping and aftertaste during krill-oil supplementation too, so individual tolerance still matters.

If you want the broader source comparison, our fish oil and krill oil guide goes further into the differences. You can also browse our omega-3 range or read more about krill oil in NZ, including sourcing and omega-3 basics.

Why we test for low odour and zero rancidity

If fish oil has repeatedly made omega-3 difficult to stick with, we think the quality of the oil and the experience of taking it both deserve attention.

Our 100% Krill Oil is cold-pressed, made in New Zealand and made without fillers or additives. We also independently test it for low odour and zero rancidity.

We care about those details because taste and smell are not small things when they affect whether you actually want to take an omega-3 supplement. Low odour does not guarantee that nobody will notice an aftertaste, and zero-rancidity testing does not guarantee universal digestive comfort. What it does show is that freshness and the experience of taking the product are things we take seriously.

For some people, that combination makes Puraz a more appealing option after a frustrating run with standard fish oil.

Before you get started

Take two Puraz 100% Krill Oil softgels once daily with food.

Because krill is a crustacean, this product contains crustacea. Do not take it during pregnancy or lactation, and do not take it if you are allergic to seafood or crustacea.

If you have a medical condition or take medication, check with a licensed health professional before use. If reflux, pain or other digestive symptoms are persistent or concerning, get appropriate professional advice rather than continuing to experiment with supplements.

If fish oil keeps putting you off, a different format may be worth trying

If standard fish oil keeps becoming the reason you stop taking omega-3, trying a different format can make sense.

Puraz 100% Krill Oil gives you a different marine omega-3 source with clearly stated EPA and DHA, plus phospholipids and naturally occurring astaxanthin. It is made in New Zealand, contains no fillers or additives, and is independently tested for low odour and zero rancidity.

We cannot promise it will suit every person or that it will eliminate fishy burps. What we can offer is a carefully made krill oil with transparent amounts and a strong focus on freshness, odour and a simple two-softgel daily serve.

Common questions

Why does fish oil make me burp?

Fish oil can cause an unpleasant taste, burping, heartburn or other mild digestive symptoms in some people. The exact experience varies with the product, formulation, timing and individual tolerance, so a fishy burp does not point to one single cause.

Are fishy burps a sign that fish oil is rancid?

Not necessarily. Freshness matters, but a fishy burp or aftertaste by itself does not prove that the oil is rancid. Formulation and individual tolerance can also affect what you notice after taking it.

Does krill oil cause fishy burps too?

It can for some people. A krill oil aftertaste or fishy burp can still happen, and published research has reported both during krill-oil supplementation. Krill oil should not be presented as a guaranteed way to avoid either experience.

Is krill oil better than fish oil for aftertaste?

Not for everyone. Some people may prefer the experience of a low-odour krill oil, while others do well with standard or odourless fish oil. We independently test Puraz 100% Krill Oil for low odour and zero rancidity, but individual tolerance still varies.

Can I switch from fish oil to krill oil?

For many adults, choosing a different omega-3 format is a reasonable option if standard fish oil is unpleasant to take. Check the new product's serving size, EPA and DHA amounts, ingredients and cautions rather than assuming the products are identical.

Does krill oil still provide EPA and DHA?

Yes. A two-softgel serve of Puraz 100% Krill Oil provides 120 mg EPA and 65 mg DHA, within 240 mg total omega-3 fatty acids.

Should I take Puraz Krill Oil with food?

Yes. Our current directions are to take two softgel capsules once daily with food.

Who should not take krill oil?

Puraz 100% Krill Oil contains crustacea and should not be taken if you are allergic to seafood or crustacea. Do not take it during pregnancy or lactation. If you have a medical condition or take medication, check with a licensed health professional before use.
