1. Is taking vitamin C good?
Vitamin C supports the production of proteins to fight pathogens, in addition, vitamin C is also an antioxidant, protecting immune cells against the damage of free radicals during the disease process. Therefore, vitamin C makes the immune system stronger, thereby enhancing the body’s resistance. When the body lacks vitamin C, the risk of infections is higher, especially respiratory infections.
The human body is not able to synthesize this vitamin on its own, but must be obtained through foods such as green vegetables, fruits such as citrus.

Therefore, taking vitamin C supplements properly every day will help get enough vitamin C needed for the body.

3. Notes when taking vitamin C cannot be ignored
Do not abuse vitamin C
Vitamin C in the small intestine is absorbed very quickly, when saturated, the excess will be excreted in the urine very quickly.
Although the toxicity of this vitamin is very low, taking too much can cause side effects such as dizziness, vomiting, and pain in people with stomach ulcers. Breastfeeding babies that take a lot of vitamin C will cause diseases such as lethargy, digestive disorders, acne, urticaria, etc. Pregnant women who use a lot are at risk of hemolytic disease.
Consider vitamin C-intolerant foods.
In some types of animal liver such as pig liver, beef liver, goat liver, … contain a lot of copper. However, vitamin C is easily oxidized when it encounters metal ions, especially copper metal ions. This means that if you take vitamin C and eat animal liver at the same time, vitamin C will lose its inherent biological functions.
In addition, milk is also a food that should not be taken with vitamin C. Most milk today contains vitamin B2, while vitamin C will be oxidized by this vitamin. At that time, both vitamin B2 and vitamin C no longer have any effect on the body. At that time, both vitamin B2 and vitamin C no longer have any effect on the body.
