O-3 fatty acids are a type of essential fatty acid that have numerous health benefits. They are not produced by the body, which means they must be obtained through diet or supplements.

O-3 fatty acids are commonly found in fish oil, but there are other natural sources as well. Here are some of the best places to find O-3 fatty acids in nature.

Fish

Fish are the most well-known source of O-3 fatty acids. Coldwater fish, such as salmon, mackerel, herring, and sardines, are particularly high in O-3s. These fish consume algae, which are rich in O-3s, as part of their diet.

The O-3s then accumulate in their tissues. For this reason, wild-caught fish generally have more O-3s than farmed fish.

However, it’s important to note that some fish, such as swordfish, shark, and king mackerel, can contain high levels of mercury and other pollutants, so it’s best to consume these fish in moderation.

Algae

Algae are another source of O-3s, and they are particularly high in the form of O-3 called EPA (eicosapentaenoic acid). Algae-based supplements are available for people who prefer a plant-based source of O-3s.

Algae-based O-3 supplements are a sustainable and vegan-friendly way to support heart, brain, and eye health. They are also an excellent option for those who suffer from seafood allergies or have ethical concerns about consuming animal products.

Nuts and Seeds

Nuts and seeds are a great source of healthy fats, including O-3s. Walnuts, chia seeds, flaxseeds, and hemp seeds are particularly high in O-3s. One ounce of chia seeds contains about 5 grams of O-3s, while one ounce of walnuts contains about 2.5 grams.

It’s important to note that while nuts and seeds are a good source of O-3s, they should not be relied on as the primary source.

Grass-Fed Meat

Grass-fed meat has more O-3s than grain-fed meat, which is higher in O-6s. This is because grass contains more O-3s than grains. Animals that are allowed to graze on grass also develop more muscle, which contains more O-3s than fat.

Beef, lamb, and bison are good sources of O-3s when they are grass-fed.

Eggs

Eggs are another source of O-3s. However, not all eggs are created equal. The amount of O-3s in eggs can vary depending on the diet of the chicken. Chickens that are fed flaxseed or fish oil will produce eggs with more O-3s.

Pasture-raised eggs are also a good option because the chickens are allowed to roam and eat a more natural diet, which can increase the amount of O-3s in the yolks.

Cod Liver Oil

Cod liver oil is a supplement that is derived from the liver of cod fish. It is a rich source of vitamin A, vitamin D, and O-3s.

Cod liver oil has been used for centuries as a traditional remedy for various ailments, such as boosting the immune system, improving bone density, and reducing inflammation. Cod liver oil supplements are available in liquid and capsule form.

Krill Oil

Krill oil is a supplement that is derived from krill, a type of small crustacean that is found in the ocean. Krill oil is an excellent source of EPA and DHA (docosahexaenoic acid), which are both forms of O-3 fatty acids.

Krill oil is often touted for its ability to support heart and joint health. It is available in capsule form.

Seaweed

Seaweed is a type of algae that is often used in Asian cuisine. It is a good source of O-3s, as well as other important vitamins and minerals. One type of seaweed called wakame contains high levels of EPA in particular.

Seaweed can be added to soups, salads, and sushi rolls for a nutrient boost.

Conclusion

O-3 fatty acids are essential for overall health and well-being.

While fish oil supplements are the most common way to obtain O-3s, there are also many natural sources available, such as algae, nuts and seeds, grass-fed meat, eggs, cod liver oil, krill oil, and seaweed. Incorporating these foods into your diet can help ensure that you are getting enough O-3s to support your health.
