DHA is necessary for some babies and not necessary for some babies, depending on whether your baby can get sufficient amounts of DHA from other foods.
DHA affects the development of the baby’s brain and also promotes the maturation of retinal photoreceptor cells. A baby’s daily intake of 70-100mg of DHA is sufficient to meet its own growth and developmental needs. If the baby can get sufficient amount of DHA from daily diet, there is no need for too much supplementation; however, if the baby’s dietary sources of DHA are insufficient, supplementation of DHA is still recommended.
To supplement DHA for babies, you can choose formula with added DHA or let breastfeeding mothers eat more DHA-rich foods such as deep-sea fish. However, it should be noted that excessive intake of DHA will increase the burden on the body and may produce free radicals that are harmful to the organism, so do not take too much supplementation.
It is recommended to follow the doctor’s advice to determine whether to supplement DHA, and do not use DHA preparations without authorization, so as not to affect the baby’s health.
