Health experts recommend that too much vitamin C increases the risk of kidney stones because it increases the excretion of calcium in the body through urine.
In response to the press, TS.BS.Ho Thu Mai, Department of Nutrition, Vinmec International General Hospital, said that vitamin C is a water-soluble vitamin. Along with many other vitamins and minerals, vitamin C is essential for good health.
However, BS.Mai pointed out: “What is used a lot is not good and neither is vitamin C.” A day, the body can only absorb the maximum amount of vitamin C of 50 to 70 mg for adults. If you take too much, the excess vitamin C will be excreted in the urine and feces. Therefore, when supplemented with too much vitamin C, it will increase the risk of kidney stones because it increases the excretion of calcium in the body through the urinary tract.
According to nutrition experts, the daily vitamin C needs of babies up to 3 years old, children’s body needs 25-30 mg, 4-18 years old needs 30-40 mg, the average adult needs 50 mg per day. day.
For pregnant women, the daily requirement of vitamin C is 50 mg, while breastfeeding is 70 mg. Therefore, to ensure the amount of vitamin C needed for the body to function, it is necessary to provide enough vitamin C in the daily diet. If the diet for some reason does not provide enough vitamin C, it should be supplemented but not taken in excess.
