The Ultimate List of Foods High in Omega 3

Omega 3 fatty acids are an essential fat that your body needs. Because your body can’t produce it on its own, you need to get omega 3 through your diet. You can find high amounts of the fatty acid in this ultimate list of omega 3 food sources.

What is Omega 3?

As an essential fatty acid, you don’t produce omega 3. Instead, you need to eat certain foods to get enough omega 3 in your diet.

Omega 3’s are ‘good’ fats as they are polyunsaturated. There are several types of omega 3’s. The main ones are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). You can find EPA and DHA in animal foods such as oily fish and algae. On the other hand, ALA is predominately in plant foods. It’s important to eat a range of omega 3 sources.

EPA, DHA, and ALA are all essential acids, so you have to get them from your diet. ALA isn’t biologically active until it’s converted into DHA and EPA1. Although your body can convert ALA to EPA and DHA, it’s in very small amounts2.

While omega 3 can be found in plant foods, it’s thought that EPA and DHA from animal products are more effective as they have the most direct health benefits3. The most important omega 3’s are DHA and EPA. This is why you find that most omega 3 supplements contain DHA and EPA.

Omega 3 for the Heart, Brain, and Eyes

Eating foods high in omega 3’s may help to prevent strokes and heart attacks. There is strong evidence on the beneficial effect omega 3 fats have on heart disease4. Researchers are currently continuing to look into the benefits of omega 3 on other health conditions.

Several studies show that omega 3’s may fight inflammation. It also supports the healthy functioning of the heart, eyes, mood, mental health, skin, and hair.

Omega 3’s are an essential part of the cell membranes throughout the entire body. As the essential fatty acid is involved in so many aspects of your health, it may have several benefits.

Our Super Strength Omega 3 Fish Oil

As you can see, one of the richest sources of omega 3 is fatty fish. Although there are some plant-based sources, it’s difficult to get enough DHA and EPA through plant foods only. While some people love fish, it’s not to everyone’s taste.

On top of this, oily fish can contain low levels of pollutants that may build up in the body. Because of this, the NHS recommends that certain groups shouldn’t eat more than two portions of oily fish a week. These groups include girls and women who are either pregnant, breastfeeding or planning a pregnancy6. This is why omega 3 fish oil supplements are so popular.

Our super-strength omega 3 fish oil supplements contain 660mg EPA and 440mg DHA per serving. The easy to swallow capsules feature the highest level of purity and are two to three times stronger than some other brands on the market.

All our supplements are non-GMO, gluten-free and made in the UK. The fish oil omega 3 capsules support normal functioning of the heart, brain, vision, mood, mental state, skin, and hair.

Omega 3’s may support several health benefits. While it’s always best to get your nutrients from your diet, supplements are an easy way to up your daily intake. With capsules, you don’t have to think about the measurement. As an essential fatty acid, it’s crucial that you get your DHA and EPA.
