Problem analysis: Vitamin C, scientific name ascorbic acid, is a water-soluble vitamin. In the human body, it plays an extremely important role, but human beings can't synthesize life-sustaining C by themselves, so they must get it with the help of food. The intake of vitamin C depends not only on simple plants, but also on some higher and purer health foods.

Guidance and Suggestions: Taking it after meals has the best effect. Tips for friends who need to take it: synthetic vitamin C is very acidic. If you take 1 ~ 4g daily, it will enhance intestinal peristalsis, cause abdominal cramps, diarrhea or stomach discomfort, and the disease resistance of white blood cells will decrease obviously. Long-term use of large doses of synthetic vitamin C may also lead to oxalic acid and uric acid stones.

I wish you the best of health!
