DHA mainly comes from deep-sea fish and marine microalgae.
DHA is only found in fish and a few shellfish. The fish with high DHA content are tuna, bonito, salmon, mackerel, sardine, horse mackerel, swordfish, tuna, yellow croaker, saury, eel, hairtail, crucian carp, etc. The DHA content can reach more than 1000 mg. For a certain type of fish, the DHA-rich part is orbital fat, followed by fish oil. Other foods such as grains, potatoes, butter, vegetable oils, lard, and vegetables and fruits contain almost no DHA.
Therefore, from a nutritional and brain health perspective, the most convenient and effective way for people to get enough DHA is to eat fish. Experts point out that it is very difficult to obtain DHA directly from marine fish. Modern science has been able to extract DHA with extremely high purity, and ordinary consumers can supplement it by eating DHA products.
There are two different sources of DHA, fish oil DHA and algal oil DHA
DHA products are mainly derived from deep-sea fish, marine microalgae. The difference between the two is that the former mainly exists in the form of ethyl ester, and the latter mainly exists in the form of triglyceride. The former has a higher absorption rate in the human body, is safer and more stable.
Fish oil DHA is mainly extracted from marine fish and has high fatty acid content. It is rich in omega-3 fatty acids, mainly EPA and DHA. The main function of EPA is to reduce blood lipids and dilate blood vessels, so it is more suitable for middle-aged and elderly people.
Algae oil DHA is firstly produced by purifying microalgae by bioengineering method, and then extracting and refining. It is rich in DHA and does not contain EPA. Algal DHA is generally safer than fish oil and is the only FDA-approved source of DHA for children.
