Docosahexaenoic acid (DHA), known also by the trivial name cervonic acid, is a long-chain n-3, or omega-3, fatty acid which is a primary structural component of the human nervous and visual systems, as well as other organs. It is a carboxylic acid with a 22-carbon chain and six cis double bonds, which give the compound high conformational flexibility. DHA is found in large quantities in breast milk and plays a key role in infant development of neural and retinal tissues. It is also favorably absorbed over other omega-3’s.


DHA is one of the essential fatty acids, which humans cannot produce and therefore must obtain through diet or nutritional supplements. DHA occurs naturally in types of marine microalgae and in other cold-water organisms such as fatty fish, in concentrations increasing with ascending position in the food chain. The best natural sources of DHA are fish and algae oils.

DHA's myriad functions in the body aren’t yet fully understood. It is mainly located in cell membranes, where its flexibility allows it to incorporate easily into membrane phospholipids and thereby significantly alters many basic properties of cells and cell membranes, including cell signaling, permeability, and protein activity, effectively rendering membranes and the gaps between cells more fluid. Among other benefits, this may help make cancer cells more susceptible to chemotherapy or immune responses. It also makes it easier for nerve cells to send and receive electrical signals. DHA's presence may moreover help stimulate production of new neurons in the brain. It is therefore thought to be crucial to brain function.

DHA helps regulate the production of many anti-inflammatory compounds in the body, and it may reduce the risk of coronary and cardiovascular disease by thinning the blood and lowering blood triglyceride levels.

Evidence suggests DHA improves cognitive function and memory, decreases inflammation, reduces the risk of heart disease and ischemic strokes, improves the outcome of autoimmune diseases, and improves vision. It may also have a positive effect on diseases such as Alzheimer’s disease, ADHD, arthritis, age-related macular degeneration (AMD), depression, diabetes, psoriasis, thrombosis, ulcerative colitis, and some cancers. Studies also show that DHA may alleviate anxiety or aggressive behavior in people in stressful situations.

A daily dosage of 200-2,200 mg of DHA may be taken. Nursing mothers beginning in late pregnancy through the first four months after childbirth are recommended to take up to 2,200 mg/day to promote infant development.

We offer DHA that has been extracted from algae in different forms and purities.
