Your body needs omega-3 fatty acids, sometimes called “omega-3s,” to stay healthy. These help to build brain cells and keep your heart and other organs in good working order.
Your body can’t make omega-3s itself. They come from the foods you eat or dietary supplements.
Fatty fish, like salmon and tuna, are rich in types of omega-3s called DHA and EPA. These healthy fats are also found in shellfish, such as crabs or oysters. A different type of omega-3, called ALA, is found in certain vegetable oils, like canola or soy oils. Flaxseeds, chia seeds, pumpkin seeds, and walnuts also contain a lot of ALA omega-3.
You can find dietary supplements that contain different types of omega-3. But most experts agree that the best way to get benefits from omega-3s is from the foods you eat. The health benefits of omega-3 dietary supplements are unclear.
If you’re thinking about taking omega-3 supplements, talk to your health care provider. That’s especially important if you take medicine that affects blood clotting or are pregnant or breastfeeding. Also check with your provider if you are allergic to seafood or considering giving omega-3 supplements to a child.
If you care about nutrition, please read studies that vitamin D can help reduce inflammation, and vitamin K may lower your heart disease risk by a third.
