Which fish oil supplement is best?

It isn’t much of a secret that many doctors and nutritionists recommend eating fatty fish such as salmon, tuna, and mackerel regularly. This is because they contain healthy omega-3s that are good for the brain, cardiovascular system, and other body parts.

But most people don’t get enough of these types of fish in their diet. This is where an excellent fish oil supplement such as New Chapter Wholemega can help. It’s made from sustainably sourced fish, contains several types of omegas and is designed to be easily absorbed into the body.

The health benefits of taking fish oil

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

Omega-3s can help fight depression and anxiety, improve eye and brain health and reduce inflammation. They can also reduce the risk of heart disease by lowering blood pressure and triglycerides, increasing HDL cholesterol levels, and preventing plaque from hardening the arteries. 

Some studies show high levels of omega-3s during the first year of life can help prevent many types of autoimmune diseases, and when taken as we age, can reduce the risk of Alzheimer’s and mental decline. They also help give the skin a more youthful look, improve the quality of sleep and more.

What to know before buying a fish oil supplement

Shelf life

Most fish oil supplements have a 24-month shelf life when stored correctly. If stored improperly, the shelf life is significantly reduced, so make sure to buy fresh supplements to ensure they don’t turn rancid before you finish the bottle. If a fish oil supplement is more than a year old when you buy it, you should consider returning it.


You should consider two things about the dosage of a fish oil supplement.

  • How many omega-3s it provides per serving. Most manufacturers list the number of milligrams on the front of the package, but that generally refers to the amount of fish oil in each serving and not how many omega-3s it provides.
  • The number of soft gel capsules in each serving. Experts generally recommend a minimum of 500 mg of omega-3s per day for the average person, but that amount can be much higher for those with certain health conditions. If you don’t like swallowing pills or have difficulty doing so, make sure you can get your recommended dosage in the least capsules possible.


Fish oil supplements are not known for having the best flavor, and some cause people to have fishy-tasting burps. If you are worried about this, look into burpless or flavored fish oil supplements.

Features to look for in quality fish oil supplements

Purity and potency

Though fish are healthy to eat, they sometimes contain harmful contaminants such as polychlorinated biphenyls and dioxins. Certain species, which happen to be many of the same ones that are high in omega-3s, may also have high levels of mercury. Make sure that any fish oil supplement you consider is purified to remove as much of these contaminants as possible.

We can’t always rely on manufacturers to be honest about the purity and potency of their supplements, so consider choosing one tested by independent labs. These include the United States Pharmacopeia, International Fish Oil Standards and the National Science Foundation. When one of these has tested a supplement, it will almost always be mentioned on the label.

If there is no indication of independent lab testing, you can look for a certificate of analysis from the company. Often you may have to go to the manufacturer’s website or request a copy of it directly from them.


When possible, choose products that focus on sustainability. For the most part, any additional cost will be negligible, but the benefits to future generations are great. To ensure your supplement is made following sustainable practices, look for a certification from the Marine Stewardship Council or a similar group.

How much can you expect to spend on a fish oil supplement

When choosig a supplement, pay attention to the cost per serving rather than the overall price. Expect to pay 10-60 cents per serving for fish oil supplements, with those made from wild-caught fish higher in price.

Fish oil FAQ

How should I store my fish oil supplement?

A. Fish oil degrades through exposure to heat, light and oxygen. To ensure the most extended shelf life, store your supplements in cool and dark places. A refrigerator is ideal, though it’s less necessary for soft gels.

Are there side effects from taking fish oil supplements?

A. The most common side effects of fish oil supplements are gastrointestinal, including belching, nausea, heartburn and loose stools. Some also experience bad breath. Taking the supplement with food can help reduce or eliminate these side effects. You should note that if you consume it in very high doses, it may interfere with blood clotting and increase the chance of bleeding.
