In infant formula, docosahexaenoic acid is approved as a nutritional supplement in various countries for infant formula. In order to normalize the brain and retina of infants and young children, FAO/WHO has approved the addition of 40 mg/100 g of DHA to infant formula. Because humans can only supplement DHA from food, it can also be used as a health food for puzzles, assisting blood fat reduction, protecting vision, preventing arteriosclerosis, anticoagulation and anti-inflammatory.

At present, various kinds of ordinary foods containing DHA have appeared on the market, including general foods such as oil, solid beverages, health drinks, sweets, noodles, ham sausages and biscuits. Adding DHA to the feed can promote the growth and development of animal pups and fry, increase the DHA content of fat in animals and aquatic products, and produce DHA-rich eggs, dairy products and low-cholesterol meat. Adding to the pet food can improve the animal's exercise ability and the fur brightness of the cat canine, and alleviate the inflammatory reaction and skin disease. As a raw material for cosmetics, DHA oil is highly permeable to human skin, and can directly deliver beneficial substances in cosmetics to the deep layers of the skin, taking into account the moisturizing effect.
