Overview

DHA (docosahexaenoic acid) is an omega-3 fatty acid. It's found in the meat of cold-water fish, including mackerel, herring, tuna, halibut, salmon, cod liver, whale blubber, and seal blubber. It can also be made by algae.

DHA is commonly used for high levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia). It is also used for boosting memory and thinking skills, for aiding infant and child development, for certain eye disorders, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse DHA with eicosapentaenoic acid (EPA). They are both in fish oil, but they are not the same. DHA can be converted into EPA in the body in very small amounts. See separate listings for algal oil, cod liver oil, fish oil, EPA, and krill oil.

How does it work ?

DHA plays a key role in the development of eye and nerve tissues. DHA may also reduce the risk of heart and circulatory disease by decreasing the thickness of the blood and lowering blood levels of triglycerides.
