What is the Best Fish Oil Supplement?

It’s no secret that many doctors and nutritionists recommend eating oily fish like salmon, tuna, and mackerel on a regular basis. This is because they contain healthy omega-3 fatty acids that are good for the brain, cardiovascular system, and other parts of the body.

Unfortunately, most people don’t get enough of these types of fish in their diet. This is where a fish oil supplement like New Chapter Wholemega can help. It is made from sustainably sourced fish and contains different types of omegas and is designed to be easily absorbed by the body, which makes it a great choice.

If you want to learn more about the benefits of taking fish oil and what to consider when choosing a supplement, we are here to help you with this guide.

The Health Benefits of Taking Fish Oil

Omega-3s are essential fatty acids that the body needs but cannot produce, which means they must come from our diet, and one of the best sources is a fish oil supplement.

It’s almost amazing when you think about the many benefits omega-3 fatty acids have on the body. They can help fight depression and anxiety, improve eye and brain health, and reduce inflammation. They can also reduce your risk of heart disease by lowering blood pressure and triglycerides, increasing HDL cholesterol, and preventing plaque from calcifying the arteries.

Some studies show that high levels of omega-3s during the first year of life can help prevent many types of autoimmune diseases, and when taken with age can reduce the risk of Alzheimer’s and mental decline. It also helps make the skin look more youthful, improve the quality of sleep, and much more.

What to Know Before Buying a Fish Oil Supplement


Most fish oil supplements have a shelf life of 24 months if properly stored. Improper storage will significantly reduce the shelf life. So buy fresh fish oil supplements to make sure they don’t go rancid before you’ve used up the bottle. If you are purchasing a fish oil supplement and it is more than a year old at the time of purchase, consider returning it.


When it comes to the dosage of a fish oil supplement, there are two things to keep in mind. The first is how many omega-3 fatty acids it provides per serving. Most manufacturers put the number of milligrams on the front of the pack, but that generally refers to the amount of fish oil in each serving, rather than the amount of omega-3 fatty acids.

The second is the number of soft gel capsules in each serving. Experts generally recommend a minimum of 500 mg per day for the average person, but this amount can be much higher for those with certain health conditions. If you don’t enjoy swallowing pills or are having trouble swallowing them, you want to make sure you’re getting your recommended amount of omega-3 fatty acids with the fewest possible capsules.


Fish oil supplements aren’t known to have the best taste, and some cause fishy-tasting burps in people. If this is your concern, then you should look for belching or flavored fish oil supplements.

Features to look for in quality fish oil supplements

Purity and potency

Although fish are healthy to eat, they sometimes contain harmful impurities such as polychlorinated biphenyls and dioxins. Certain types, many of which are high in omega-3 fatty acids, can also be high in mercury. You want to make sure that every fish oil supplement you are considering is cleaned to remove as many of these contaminants as possible.

Unfortunately, we cannot always rely on manufacturers to be honest about the purity and effectiveness of their supplements. Hence, it is often best to choose one that has been tested by independent laboratories. Some organizations that certify fish oil supplements are the United States Pharmacopeia, International Fish Oil Standards, and the National Science Foundation. Every time a dietary supplement has been tested by one of these organizations, it is almost always mentioned somewhere on the label.

If there is no evidence of independent laboratory testing, you can search for a company’s certificate of analysis. Often times, you’ll need to go to the manufacturer’s website or request a copy of it directly.


If possible, it is best to choose products that are geared towards sustainability. The additional costs will be largely negligible, but the benefits for future generations are not quantifiable. To make sure you are choosing a supplement that is made using sustainable practices, look for certification from the Marine Stewardship Council or a similar organization.

How much can you spend on a fish oil supplement?

Every time you decide to buy a supplement, it’s important to look at the cost per serving rather than the total price of the purchase. For fish oil, you can expect 10-60 cents per serving, with those from wild-caught fish being at the upper end of the price spectrum.

Frequently asked questions about fish oil

How should I store my fish oil supplement?

A. Fish oil is susceptible to degradation from heat, light, and oxygen. To ensure the longest possible shelf life, you should store your food supplements in a cool and dark place. A refrigerator is an ideal place, although it is not 100% necessary for soft gels.

Are there any side effects from taking fish oil supplements?

A. The most common side effects of fish oil supplements are gastrointestinal side effects such as belching, nausea, heartburn, and loose stools. Some also have bad breath. Usually, taking them with food can help reduce or eliminate these side effects. You should be aware that if you consume fish oil supplements in very high doses, they may interfere with blood clotting and increase the chance of bleeding.
