There are no specific rules about when it is best for infants to take DHA at any point in time. However, it can generally be supplemented after 6 months of age and can be taken after or with meals. Specific instructions should be followed by your doctor. DHA is a very important unsaturated fatty acid in the human body, and is an important component of the brain and retina, which is important for the development of intelligence and vision in infants. After 6 months of age, infants grow rapidly and their nutritional needs increase further, so DHA can be supplemented appropriately to promote the baby’s hand-eye coordination and so on. DHA can be added from complementary foods, such as DHA that can be obtained from deep-sea fish and other foods, but not the more the better, and supplementation beyond the required amount is harmful. Therefore if DHA supplementation is necessary, it must be done under a doctor’s supervision and can be taken after or with meals to promote absorption.
