DHA (DOCOSAHEXAENOIC ACID) is an Omega-3 fatty acid found in cold-water fish, including mackerel, herring, tuna, halibut, salmon, cod liver, and other seafood, with the potential to reduce inflammation. DHA is a precursor to the neuronal cell wall and can increase the thickness of the blood and lower triglyceride levels. It is used not only for cardiovascular problems but also for dementia, diabetes and ADHD. It is essential in the development of nerve membranes and is given to babies to enhance development. Because DHA is also implicated in the development and health of eye tissue it is also used in cases of Macular Degeneration.
