Vitamin A: According to American medical research, if pregnant women take large amounts of vitamin A, it will increase the incidence of cleft lip and palate, congenital heart disease and central nervous system abnormalities in newborns. The recommended daily intake for normal people is about 2000IU, and for pregnant women, it should reach 3000IU. If the daily intake exceeds 10,000 units, the chance of fetal defects continues to increase. If the intake exceeds 20,000 units, the rate of fetal defects increases fourfold. The most frightening thing is that vitamin A and vitamin D are stored in body fat, so excessive intake before conception may also lead to fetal malformations in the future.

Vitamin D: The recommended daily intake of vitamin D is approximately 400 units. Vitamin D can be obtained from natural foods, nutritionally fortified foods and ultraviolet radiation from the sun, so there is no need to deliberately increase your intake during pregnancy. If you consume too much, it may cause hypercalcemia in the mother and fetus. Ingesting more than 4,000 units can cause neonatal growth retardation, weird facial shapes, aortic atresia and other problems. There may be a greater risk if antacids are used at the same time.
Vitamin E: The recommended daily intake of vitamin E is approximately 10-20 units. This vitamin is ubiquitous in food, so deficiency is rare. Some scholars suggest that vitamin E can be used to treat or prevent cardiovascular disease, thromboembolism, infertility or prevent aging. There is currently no clear medical evidence that overdose of vitamin E will have adverse effects on pregnant women or fetuses. Overnutrition becomes a \”new disease\” for pregnant women
Vitamin C: Although the claim that taking vitamin C can treat or prevent colds has been questioned by the medical community, it has been accepted by everyone. It is recommended to consume about 30-60 mg of vitamin C daily. Insufficient vitamin C can cause scurvy, but too much vitamin B12 can affect absorption and metabolism, as well as fetal oxidation. Therefore, it is not recommended to take large amounts of vitamin C during pregnancy. Men who often eat seafood can cause infertility
