The recommended amount of The Dietary Guidelines for Chinese people is 100 mg Vitamin C.

If you intake of vitamin C is too low, it may cause scurvy, swollen gums,bleeding,and increased subcutaneous ecchymosis after a fall, prolonging and delaying the healing of wounds.

If you intake of vitamin C is too much, it may have a certain impact on the metabolism of calcium, and the risk of urinary calculi will be relatively higher. Therefore, in nutrition, there is a tolerable, maximum intake and appropriate intake, the most suitable intake of vitamin C, for normal people, the daily intake is about 100mg.

Vitamin C is an essential nutrient for the human body. We should consume it every day. Vitamin C remains in the body for a short time and must be ingested from fruits and vegetables. Fresh vegetables and fruits are rich in vitamin C. The recommended intake of vitamin C is 80-100mg per day. For example, an apple with 250g or an orange with 200g contains 100mg of vitamin C, which is enough for daily needs.

According to the FDA's requirements for dietary supplements, people of different ages have different intakes of vitamin C.

Adults and children ≥ 4 years


Infants through 12 months


Children 1 through 3 years


Pregnant women & lactating women


As can be seen from the above figure, adults and children ≥ 4 years is 90mg, it is lower than Chinese standard.

An appropriate amount of vitamin C supplementation for pregnant women can prevent congenital malformations of the fetus. The dietary vitamin C intake of pregnant women is increased from 90 mg to 120 mg per day for non-pregnant women to meet the needs of the mother and the fetus.
