What is the difference between EPA and DHA?


EPA and DHA are both Omega-3 fatty acids, but they have different chemical structures. DHA is a major component of human tissues (including the brain, skin, and other soft tissues), and EPA is not only a precursor of DHA, but has also been found to inhibit certain liver enzymes and can be used to treat schizophrenia and depression.
DHA and EPA also help reduce triglyceride levels in the blood and can improve cardiovascular health. Both ingredients are available in the diet through fish oil-containing Omega-3 supplements.
