What it does: DHA supports brain cell structure, promotes efficient nerve signaling, and is crucial for the development and function of the brain and eyes throughout life.
How it is used: Commonly taken in supplements for cognitive support, early childhood and prenatal nutrition, and healthy visual function, as well as to help maintain brain performance with age.
Natural sources and supplement forms: DHA is naturally abundant in fatty fish (such as sardines, salmon, and mackerel) and marine algae. Supplement forms include fish oil, algae oil, and krill oil, typically provided as capsules, softgels, or liquid oils.
Why it appears in supplement formulas: People use DHA supplements to help reach optimal brain and eye DHA levels, especially if their diets lack regular omega-3-rich seafood, or during pregnancy, infancy, and aging when DHA needs may be higher.
What to know before use: DHA may have mild blood-thinning effects; consult your healthcare provider if you use blood thinners or have a bleeding disorder.
Interesting Fact
DHA: The Main Omega-3 Found in Your Brain
Docosahexaenoic acid (DHA) is the most abundant omega-3 fatty acid in the human brain and the retina of the eye. Naturally found in fatty fish like salmon and sardines, DHA helps build and maintain healthy cell membranes, especially in nerve and eye tissues. Many supplement formulas include DHA to help support the natural levels found in these key parts of the body.
