If you add dha to your baby, you can choose to add complementary food at the age of six months, and then add dha after the milk volume is reduced to promote the development of brain and vision, which can be supplemented to two years old. Dha is generally recommended for babies to take with meals, that is, it is not used during or after meals, which can be better absorbed. It is not recommended to take DHA before meals or on an empty stomach. There is no strict restriction on whether to take it in the morning or at night, and it is usually taken during or after meals.
