What is Fish Oil?

Fish oil is a dietary supplement made from the oils of fatty fish like sardines, mackerel and salmon. It’s rich in omega-3 fatty acids, which are essential fats that offer various health benefits. These omega-3 fatty acids include EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Supplements allow for more control of the dosage of omega-3 fatty acids, making it easier to ensure that you are getting a consistent amount of these beneficial nutrients.

Fish oil supplements are a convenient way to increase your daily dose of “good” fats because you can take them on the go, with no fish cooking required. Plus, if you don’t like the taste of fish, supplements are a great alternative as high-quality brands minimize the fishy taste and odor.

You can take fish oil in capsule or liquid form. It’s a popular supplement that supports overall well-being, as you can see from the following benefits.

The Science-Backed Benefits of Fish Oil

Workouts

Fish oil supplements may have the potential to help improve strength training, according to a recent research study.9 When combined with resistance exercise training, fish oil supplements improved upper-body and lower-body strength compared to participants taking a placebo. Taking a fish oil supplement could be a cost-effective nutritional strategy to support general health and training, especially if you don’t often eat fish.

Digestive Discomfort

Another scientific study looked at the link between the regular use of fish oil supplements and the risk of developing inflammatory bowel diseases (IBDs).10 Researchers concluded that habitual intake of fish oil supplements potentially led to a lower risk of IBDs. Though more research is needed, fish oil supplements may be recommended for the control and prevention of such health conditions.

Brain Health

And finally, fish oil supplements may support cognitive memory, according to a two-year research study.11 Participants taking fish oil supplements recorded significantly fewer errors in working memory tasks than those receiving the placebo. And even as tasks got harder, the active group did better than the placebo group. Increasing fish oil intake could be beneficial in lessening the risk of dementia later in life and reducing cognitive decline.

FAQs

What are the side effects of taking fish oil supplements?

Fish oil supplements are generally safe for most people, but they can cause some side effects. Some of the most common side effects include fishy aftertaste, bad breath, heartburn and acid reflux. Most of these symptoms are mild and go away on their own. However, if you have a bleeding disorder or are taking blood-thinning medications, you should talk to your healthcare provider before taking fish oil supplements because of the increased risk of bleeding.

What is the recommended dosage of taking fish oil supplements?

While there is no set recommendation for how much fish oil you should take, there are recommendations for total omega-3 intake, including EPA and DHA. For healthy adults, 250-500 milligrams of combined EPA and DHA per day is a common dosage12. However, you may want to increase your dose if you’re targeting a specific health condition. Speak to your healthcare provider to determine the correct dose for your lifestyle.

How do I choose high-quality fish oil supplements?

If you’re considering adding fish oil supplements to your wellness stack, make sure you choose the highest quality. Look for omega-3 supplements that are third-party certified to ensure the product is sustainable and free of contaminants. You can also verify the EPA and DHA amounts on the label to make sure they meet your needs. Only buy from a reputable brand that invests in the quality of the ingredients and testing procedures.

If I regularly eat fish, do I still need to take fish oil supplements?

It depends. Even if you regularly eat fish, not all fish species contain the same amount of omega-3s, so it can be difficult to accurately monitor how much you’re getting in your diet. Plus, if you’re concerned about the quality of the fish you’re eating, you may want to take supplements to avoid contaminants. However, whether you should take fish oil supplements is based on your individual needs and dietary habits. Speak to your healthcare professional to discuss your options.

How should I store my fish oil supplements?

Fish oil is sensitive to heat, light and oxygen, so storing them properly is essential to maintaining their freshness and efficacy. Store your supplements in a cool, dark place, away from direct sunlight and heat sources, like a pantry. You can even keep them in the fridge to extend their shelf life. Ensure you close the container properly after each use to minimize air exposure, which can lead to oxidation and spoilage. And finally, aways check the expiration date and discard any supplements that have expired.

How long does it take to see the benefits of fish oil?

Fish oil supplements are not a quick-fix solution. You may need to wait several weeks with consistent use before you notice any changes to your health. If you want to target a specific health goal, speak to a healthcare professional who can help you determine the right doses and monitor your progress over time.

I’m vegetarian. What’s an alternative, plant-based omega-3 supplement?

If you’re on a plant-based diet and looking for an alternative to fish oil that provides omega-3 fatty acids, consider taking algae oil supplements. Algae oil is derived from marine algae and is a sustainable and vegan source of omega-3s, specifically EPA and DHA.

What’s the difference between fish oil vs krill oil?

Fish oil and krill oil are both sources of omega-3 fatty acids, but they have some differences. Fish oil is derived from the body tissues of fatty fish like salmon, mackerel, sardines, and anchovies, whereas krill oil comes from tiny shrimp-like marine crustaceans known as krill. Fish oil typically contains higher levels of both eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA), which are the two primary omega-3 fatty acids. In terms of potential side effects, krill oil is less likely to cause fishy burps or gastrointestinal issues, making it more tolerable for some people. Both fish oil and krill oil can offer various health benefits, including supporting heart health, reducing inflammation and promoting brain function.
