DHAcontaining

DHA-containing refers to foods, supplements, or other products that provide docosahexaenoic acid (DHA), a long-chain omega-3 fatty acid. DHA is a major structural component of neural and retinal membranes and is studied for its roles in brain development, cognitive function, and visual health. Products described as DHA-containing are intended to deliver specific amounts of this fatty acid.

Natural sources of DHA include fatty fish such as salmon, sardines, mackerel, and herring, which supply DHA in triglyceride form. Algae-based DHA supplements offer a vegetarian or vegan source. DHA is also added to certain fortified foods and infant formulas; examples include DHA-enriched eggs, some dairy products, fortified beverages, and various brands of infant formula.

Health considerations: Adequate DHA is associated with supporting fetal and infant neurodevelopment and may contribute to cardiovascular health in adults, though evidence varies by outcome. Dietary guidelines for DHA and total omega-3 intake differ by country, with many authorities recommending several hundred milligrams per day of combined DHA and EPA for adults and higher amounts during pregnancy and lactation. Fish consumption can carry contaminants, so selecting low-mercury options or using algal DHA supplements can mitigate risk. People with dietary restrictions can obtain DHA through supplements or fortified foods.

Labeling and regulation: Nutritional labels often indicate DHA content per serving in milligrams, and some jurisdictions regulate health claims related to DHA. Storage and stability: DHA is prone to oxidation, so products may include antioxidants or be packaged to protect freshness.
