How much vitamin C should pregnant women take a day? What will happen if pregnant women take too much vitamin C?

Supplementing vitamin C is very important for both pregnant women and fetuses. Appropriate supplementation of vitamin C is beneficial to the growth and development of the fetus. So what is the daily standard for pregnant women to supplement vitamin C?

Experts recommend that pregnant women and nursing mothers in the second and third trimesters should take 130 mg of vitamin C per day to meet their daily needs. This amount is relatively small. As long as pregnant mothers have a balanced diet and are not picky about food, their daily diet can meet their needs. Generally, eating more than half a pound of vegetables and fruits every day can meet the normal physiological needs.

1. Affecting fetal development: Excessive intake of vitamin C (more than 1000 mg) by pregnant women will affect embryonic development. Long-term excessive intake can also cause scurvy in the fetus after birth.

2. Long-term excessive intake of vitamin C may cause gastrointestinal discomfort, such as diarrhea, frequent urination, nausea and vomiting, stomach cramps and other discomfort symptoms.

3. Stone formation Although vitamin C is water-soluble, long-term excessive intake of vitamin C will still cause a heavy burden on the body, and may form urate, cysteine ​​or oxalate stones, leading to the formation of urinary stones.

4. Leading to the deficiency of other nutrients. The large absorption of vitamin C has a destructive effect on vitamin A and folic acid. Therefore, long-term and large intake of vitamin C will lead to the deficiency of vitamin A and folic acid in the body, which is also very harmful to pregnant women and fetuses.

5. Induce thrombosis. A large amount of vitamin C in the body will inhibit the anticoagulant effect of heparin, dicoumarin and other components in the human body, causing blood coagulation to worsen and blood clots to form easily. Therefore, long-term use of excessive vitamin C may cause thrombosis.

1. Dietary supplements: If a pregnant woman lacks vitamin C, it is best to take dietary supplements. Many foods in life are high in vitamin C, such as cabbage, rapeseed, bitter melon, chrysanthemum, tangerines, oranges, strawberries, persimmons, kiwis and other fresh fruits and vegetables.

2. If the pregnant woman is seriously deficient in vitamin C, she needs to take vitamin C tablets orally while taking food supplements. For mild cases, take 200-300 mg of vitamin C per day, and for severe cases, 300-500 mg. The dose should be increased during infection and taken three times before or during meals. However, the specific dosage should be followed according to the doctor's advice.

1. Preventing anemia: Vitamin C can promote the absorption of iron and reduce oxidized trivalent iron to divalent iron. Appropriate supplementation by pregnant women can help prevent anemia during pregnancy.

2. Prevent scurvy Vitamin C promotes the healthy hematopoietic system of the fetus and enhances the body's resistance. If it is deficient, it is easy to suffer from scurvy. Appropriate supplementation during pregnancy can prevent the fetus from suffering from this disease after birth.

3. Avoid abnormal fetal brain development. The vitamin C content in the blood is closely related to intelligence. If pregnant women do not pay attention to supplying vitamin C from their diet, the baby will have poor brain development and even lead to brain dysfunction.

4. Whitening skin Vitamin C is an antioxidant that can excrete melanin from the body to keep the skin white and tender. Pregnant women can make their skin fair by taking an appropriate amount of vitamin C.
