DHA is a polyunsaturated omega-3 fatty acid (PUFA) found throughout the body but most abundant in the brain, eyes and heart. It is a major structural fat found in the brain and eye accounting for up to 97% of the total omega-3 fats in the brain and up to 93% of the omega-3 fats in a specific part of the eye, called the retina. It is also a key component of the heart. Numerous research studies confirm that everyone, from infants to adults to the elderly, can benefit from a regular intake of dietary DHA. Just as calcium is essential for building strong bones, DHA ensures that the cells in the brain, eyes, heart and other parts of the nervous system develop and function properly through all stages of life.
