I used to keep a bottle of fish oil pushed to the back of my cabinet because every time I tried to be “consistent,” it came with a little penalty: a fishy repeat that crept up during my commute or a stomach that felt touchy before I even finished my coffee. After one too-many mornings of regretting it at my desk, I started paying attention to the details I had ignored, like freshness, softgel coatings, and taking it with a real meal instead of on an empty stomach. Switching to a burp-less style made the whole thing feel quieter and more predictable, like my gut stopped protesting and I could finally stick with omega-3s without bracing for the aftertaste.

Buying Guide
How to Take Fish Oil Without Upsetting Your Stomach
Start with timing: fish oil is usually happiest with food. Taking it mid-meal (not before) often reduces reflux, nausea, and “fishy repeat.” If you are taking multiple softgels, split them between breakfast and dinner instead of doing it all at once.
Use the temperature trick: keeping softgels in the fridge, or even the freezer, can make them feel gentler and cut down on aftertaste for some people. For liquids, treat the bottle like a fresh ingredient: recap quickly, refrigerate after opening, and avoid letting it sit out on a warm counter.
Prioritize freshness: if a fish oil smells strongly fishy when you open it, or tastes sharp and unpleasant (for liquids), do not force it. A fresh product is easier to take consistently, and consistency is what makes a supplement routine feel worthwhile.

Frequently Asked Questions ▾
What makes a fish oil “good for gut health”?
For most people, it is less about a special ingredient and more about tolerability and quality. Look for a fish oil that is fresh, has clear labeling for EPA and DHA, and is easy on your stomach (enteric-coated softgels or a well-flavored liquid can help). A consistent routine matters more than chasing the highest number on the front label.
How do I avoid fishy burps or reflux?
Take fish oil with a full meal, not on an empty stomach. Many people do better splitting the dose between breakfast and dinner, and keeping softgels in the fridge or freezer can reduce “repeat” aftertaste. If you are very sensitive, try an enteric-coated softgel so it opens lower in the digestive tract.
How long does it take to notice benefits?
Fish oil is not usually a quick, same-day supplement. Many people reassess after a few weeks of consistent use, especially if they are taking it to support an overall healthy inflammatory response. If you are using it for a specific health concern, it is worth checking in with your clinician for a personalized plan.
How can I tell if my fish oil has gone rancid?
A strong, unpleasant fishy smell when you open the bottle, or a sharp taste (for liquids) can be a red flag. Store it away from heat and light, keep the lid tightly closed, and follow “refrigerate after opening” directions for liquids. When in doubt, replace it, since freshness is a big part of both comfort and quality.
Who should be careful with fish oil?
If you are pregnant, nursing, have a bleeding disorder, are preparing for surgery, or take blood thinners or certain anti-inflammatory medications, ask your healthcare provider before starting. Also use caution with fish allergies, and stop if you get persistent digestive upset or any signs of intolerance.
