How to eat vitamin C

Vitamin C mainly comes from vegetables and fruits. The fresher the fruits and vegetables, the higher the vitamin C content. It is worth noting that vitamin C is extremely soluble in water, not heat-resistant and easily oxidized, and boiling for a long time will make the vitamins in fruits and vegetables

Vitamin C is lost, so it is recommended to use cold salad or quick frying to preserve more vitamin C when cooking.

  1. Do not take vitamin C on an empty stomach: vitamins are water-soluble and have a relatively small molecular structure, which is easily absorbed by the body. However, if you take vitamin C on an empty stomach, it will cause a surge in blood concentration and be easier to excrete.
  2. Take it twice for breakfast and dinner: It is recommended to take vitamin C in two doses, one for breakfast and another for dinner, which helps to maintain the concentration of vitamin C in the blood throughout the day.
  3. Take it once a day before going to bed: For busy office workers and students, if taking vitamin C twice is easy to forget, you can try taking it every day before going to bed. When sleeping, because the kidney metabolism will slow down, vitamin C is easier to retain in the body, and the blood concentration will remain relatively high. Therefore, supplementing vitamin C before going to bed can also achieve the same effect.
