DHA can promote the growth of nervous system cells and the maturation of retinal photoreceptors, which is very important for the development of infants' intelligence and vision. Generally, the period after 0/6 weeks of pregnancy belongs to the period when the neurons in the fetal brain nerve center divide and mature rapidly, which is the time when the demand for DHA by the fetus and the mother is large. Therefore, it is usually recommended to start DHA supplementation around 0/6 weeks of pregnancy, which is very beneficial to pregnant women and fetuses.

DHA is an unsaturated fatty acid. It is recommended for pregnant women to take it after meals when taking it, and it is generally not easy to be absorbed on an empty stomach.

Because excessive DHA supplementation is not good for babies and mothers.
