Routine DHA supplementation is generally not recommended for newborns; if necessary, consult your doctor. DHA is a nutritional supplement, an unsaturated fatty acid, which can promote brain development and retinal development to a certain extent. If necessary, DHA can be taken after 6 months of life under the supervision of a doctor, but it is not recommended for newborns. Newborns are small babies who are separated from their mothers from the time the umbilical cord is tied until 28 days after birth, and usually do not need additional DHA supplementation, especially for breastfed babies, as breastmilk is rich in DHA, which can satisfy the daily needs of babies. It is also important to note that DHA preparations are mostly health supplements and are not intended to treat diseases and cannot replace regular medications. If you are suffering from a disease, you need to go to the hospital for examination and treatment in a timely manner, so as not to miss the diagnosis and treatment time.
