Vitamin c, how to supplement

Vitamin c, do you want to supplement it?

In theory, people can get enough vitamin C from food.

However, if you choose too few foods containing vitamin C in your daily diet, you may not be able to obtain vitamin C from your food to meet your needs. In addition, some living habits can also cause the loss of vitamin C in food. Vitamin C is water-soluble, and part of it will be lost when washing and soaking; Vitamin C is easily oxidized and cannot be stored for a long time; Vitamin C is not resistant to high temperature. If the heating temperature is too high or the heating time is too long, it will lose a lot.

At the same time, some individual reasons may also lead to vitamin C deficiency, such as the relative increase of body demand and the reduction of absorption and utilization rate: the demand for vitamins is relatively increased in pregnant and lactating women, growing children and patients in the recovery period of disease; The elderly have lower gastrointestinal function and lower absorption and utilization of vitamins. In these cases, it is easy to cause vitamin C deficiency. At this time, appropriate supplementation is also beneficial.

In addition, vitamin C also has incompatibility. Studies have found that vitamin C can not be used with a variety of trace elements and pantoprazole sodium.
