Pros and Cons of Fish Oil Supplements
Although Omega-3 fatty acids have many impressive benefits, fish oil supplements aren’t right for everyone, and they come with some potentially serious side effects. So, whether you’re looking for the best fish oil supplements or considering ditching your fishy pills, here are the pros and cons of fish oil supplements:
CONS:
1. Fishy Taste
Unsurprisingly, fish oil supplements can taste extremely fishy and leave an unpleasant aftertaste even when you wash them down with a drink. While many manufacturers claim to filter out the impurities that cause the fishy flavor (or mask it with lemon extract), many fish oil supplements will leave a bad taste in your mouth…
2. Stomach Issues
Taking fish oil supplements may cause stomach issues – such as indigestion, nausea, and loose stools – especially in people with gastrointestinal issues like Crohn’s Disease. Fortunately, many of the best fish oil supplements use enteric coatings, which keep the capsules from dissolving until they reach the small intestine and remove most potential stomach issues.
3. May Worsen Bleeding or Blood Pressure Issues
The National Institutes of Health (NIH) warn against taking high-dose omega-3 supplements with blood thinning medication, as they can increase the risk of bleeding or easy bruising. Although these drug interactions are relatively rare, you should ask your doctor about taking fish oil supplements if you’re on any blood-thinning medicine.
4. Incomplete Nutritional Profile
While fish oil supplements are a great source of Omega-3 fatty acids, they lack other nutrients in oily fish like sardines, which are an excellent source of vitamin B12. While some of the best fish oil supplements contain added nutrients like vitamin B12, eating oily fish (if you enjoy it and have easy access to a good grocery store) is a better option for rounded nutrition.
PROS:
1. Convenience
Fish oil supplements are a much easier way of getting your recommended intake of Omega-3 fatty acids than food sources, as they require no cooking, can be safely stored for years, and are easy to take.
2. Cost
Gram for gram, fish oil supplements are a much cheaper source of Omega-3 fatty acids than natural food sources, and the best fish oil supplements help you get your daily recommended intake of Omega-3 fatty acids for less.
3. Concentration
Some fish oil supplements feature extremely high concentrations of Omega-3s, with some brands containing more Omega-3s than an entire serving of salmon!
Types of Fish Oil Supplements
As the old saying goes, “there are plenty of fish in the sea”, and there are plenty of types of fish oil supplements available, ranging from natural green-lipped mussel oil to DHA-enriched fish oil. The main difference lies in how it’s processed, so we’ve listed the properties of each of the main types to help you find the best fish oil supplements for your needs:
Natural Fish Oil
Derived from the flesh of fatty fish like herring, mackerel, sardines and salmon, the Omega-3 fatty acids in natural fish oil are mostly present in their triglyceride forms, which means they can be easily absorbed.
Processed Fish Oil
Many food chemists convert the triglycerides into ethyl esters during the refinement of fish oil, which allows them to adjust the concentrations of DHA and EPA to try and create the best fish oil supplements.
Reformed Fish Oil
After refinement, chemists can convert the ethyl esters back into triglycerides to improve absorption, and the finished fish oil is often termed “reformed.”

Capsules
The most common form of fish oil supplements is capsules and softgels, as they are easy to swallow and mask the fishy taste. Furthermore, some of the best fish oil supplements are enteric coated, which minimises the risk of stomach issues even in higher doses.
Liquid
You can also buy fish oil in a bottle, which allows you to adjust your preferred dose easily, but it tends to be less popular, since there is no ignoring the taste and smell in this form.
Conclusion
While Omega-3 fatty acids have some amazing health benefits – helping tackle inflammation and fatty liver whilst supporting heart, eye and mental health – there are some potential side effects you need to be aware of. Fortunately, fish oil is widely considered safe, and the best fish oil supplements are designed to minimise any downsides like fishy aftertaste.
As a final word of warning, you should avoid high-strength omega-3 supplements if you take blood-thinning medication due to potential interactions and always consult a medical professional before starting a new supplement routine.
