Pregnant women and lactating mothers need a reasonable diet to maintain DHA level, which is beneficial to maternal and infant health. According to the Nutrition Society of China, the daily intake of DHA by pregnant women and lactating mothers is not less than 200mg. By eating fish 2-3 times a week, and more than 1 meal is fatty marine fish, and eating eggs 1 meal every day, people's brains begin in the third month of pregnancy and end when they are 2-3 years old. The fetus obtains DNA from the mother through the placenta. In the third month of pregnancy, the fetal brain begins to develop and the DNA content reaches the maximum.

If the mother lacks DNA, it will cause the fetus to have a serious picky eater and partial eclipse, so it is enough to supplement with food, and there is no need to add DHA supplements. Usually, we should pay attention to let the baby eat more fish, especially deep-sea fish, such as salmon, eel, tuna, yellow croaker, saury, metapenaeus ensis, etc., which may be related to the baby's brain development and visual development. The 20 15 DHA Supplementary Guide for Pregnant Women and Infants recommends that pregnant women and lactating mothers take 200 mg of DHA every day, and infants take 100 mg every day.

To sum up, if all kinds of trace elements meet the standards, eating normally and breastfeeding will be enough. If you don't think it's enough, or you're not at ease, you can prescribe some for your baby and supplement it in moderation. The cells develop healthier. If you take enough in the critical period of brain development (before the age of 6), you can increase your baby's nerve branches. There are more nerve branches, more channels to transmit information to the brain, and more stimuli to the brain. A major component of the baby's natural cell growth and maintenance is the important component of the brain and retina, which is very important for children's intelligence and vision development. Supplement can't guarantee children to become smart, but it is absolutely impossible without it. Since it is so important for children to take supplements, DHA is distributed among various organs and tissues of the human body, such as the brain. DHA can help the development of baby's brain neurons and synapses, and it is an important nutrient in the development of baby's brain.
