What is DHA?
DHA stands for Docosahexaenoic Acid. It is a special kind of fat. This fat is very good for your body. It belongs to a group called Omega-3 fatty acids. These fats are healthy and important for life.
DHA is found mostly in fish and some algae. Our body needs DHA to work well. It helps many parts of the body, especially the brain and eyes.
Why is DHA Important?
DHA is a key building block for the brain. About 60% of the brain’s fats are DHA. That means it helps the brain grow and work well.
DHA is also very important for the eyes. It helps keep the eyes healthy. People with good DHA levels often see better than others.
Besides the brain and eyes, DHA helps the heart. It can support healthy heart function and lower risks of heart problems.
Where Can You Find DHA?
We get DHA mainly from food. Here are some common sources:
- Fatty fish like salmon, tuna, and mackerel
- Fish oil supplements
- Algae oil supplements (good for people who don’t eat fish)
- Eggs from chickens fed with DHA
Many people do not eat enough fish. So, they may take DHA supplements to get enough of this important fat.

How Does DHA Work in the Body?
After you eat or take DHA, your body absorbs it. DHA becomes part of your cells. It helps cells send signals and work better.
In the brain, DHA helps nerve cells connect. This helps you think, learn, and remember.
In the eyes, DHA helps keep the retina healthy. The retina is the part that helps you see clearly.
DHA vs. Other Omega-3s
DHA is one of three main Omega-3 fats. The other two are EPA and ALA:
- DHA: Good for brain and eyes
- EPA: Helps reduce inflammation and support the heart
- ALA: Found in plants like flaxseed and walnuts
DHA and EPA come mostly from fish oil. ALA comes from plants. The body can change some ALA into DHA and EPA, but not much.
Who Should Avoid DHA Supplements?
Most people can take DHA safely. But some should be careful:
- People with bleeding problems
- Those taking blood-thinning medicine
