Docosahexaenoic Acid (DHA) is a polyunsaturated fatty acid (C22H32O2) with six double bonds and is an omega-3 essential fatty acid. Fish oil is rich in DHA. Most DHA in fish and other organisms originate from photosynthetic and heterotrophic microalgae. The more DHA components in the upper layer of the food chain. DHA is also commercially extractable from the microalgae Crypthecodinium chonii and Schizochytrium. DHA produced using microalgae is vegetarian. Most animals rarely produce DHA by metabolism. Although α-linolenic acid (ALA) is also an omega-3 fatty acid, the efficiency of ALA conversion to DHA is extremely poor, and ALA cannot be used by humans, so DHA Additional supplements are required.
DHA is a fatty acid found in the meat of cold-water fish, including mackerel, herring, tuna, halibut, salmon, cod liver, whale blubber, and seal blubber.
Don’t confuse DHA with EPA (eicosapentaenoic acid). They are both in fish oil, but they are not the same. DHA can be converted into EPA in the body. See separate listings for fish oil and EPA.
DHA is used as a supplement for premature babies and as an ingredient in baby formula during the first four months of life to promote better mental development.
