Preferably immediately after a meal. Depending on the absorption rate, vitamin C is more effectively ingested three times a day, and this can also prevent the *** caused by high doses of vitamin C. 2 The recommended intake of vitamin C for pregnant women and nursing mothers in the middle and third trimesters is 130mg daily.
Note: The amount of VC required varies greatly from person to person. Some people can supplement a small amount to satisfy, and some people can reach 10 grams per day or even higher.
The final important product of vitamin C catabolism in the body is oxalic acid, which can cause oxaluria to form urinary tract stones when taken for a long time. Overdose can cause adverse reactions: taking 1 4g per day can cause diarrhea, rash, increased gastric acid, gastric reflux, sometimes urinary stones, increased urinary oxalate and urate excretion, deep vein thrombosis, intravascular hemolysis or coagulation, etc., sometimes leading to a decrease in leukocyte phagocytosis.
When the daily dosage exceeds 5g, it can lead to hemolysis, and in severe cases, it can be fatal. When pregnant women take large doses, infant scurvy may occur. Heating, light, light, and prolonged storage can all cause vitamin loss and decomposition.
Parasites, taking mineral oil, excessive amounts of dietary fiber, etc., can hinder the absorption of vitamins. People with poor kidney function should not take more vitamin C. Long-term overdose of vitamin C may cause hyperacidity, gastric reflux, and even urinary stones.

The strong reducing property of vitamin C can reduce the trivalent iron in food to ferric iron that is conducive to human absorption, and promote the storage of ferritin, which is conducive to the prevention of iron deficiency anemia.
5. Promote collagen formation. Cover early.
Vitamin C can promote collagen formation, 1 adult has about 3 kg of collagen in the body, if there is a lack of vitamin C, collagen synthesis is blocked, so that the wound heals slowly, not only affects our skin, but also leads to problems with blood vessels, bones, internal organs, etc.

8. Maintain the normal function of bones and gums.

All brands of VC are health care products, and the content is far from standard. There are many other substances.
If you are in good health, do not eat indiscriminately.
Instead, listen to your doctor's advice. Believe in the science of diet. (Eating vitamins is an extremely unscientific so-called tonic).
A few more verbose words:
The growth and survival of human beings depends on normal, scientific diet + activity. Don't listen to it and believe it, and don't eat vitamin tablets as a daily essential food, eating too much is harmful!
For example, vitamin E is fat-soluble, and if it is taken for a long time beyond the safe amount, it will lead to phlebitis, pulmonary embolism, blood fat and other high levels***, so it should be taken with caution. Try not to accept it until the age of twenty-four.
Try not to eat more sun activities, (not sun exposure). It is conducive to nutrient absorption.
At present, many young people, especially young people, have misconceptions about taking vitamins. Special examples:
In fact, no matter what brand of VE VC, the main thing is to look at the quality. Everything on the market is foolish, because: from a scientific point of view, there is only one chemical formula of VE in the world. Otherwise it would not be possible to call ve
The same goes for VC)
What is natural, synthetic, diverse, and so on, is all imaginary.
The main thing is that the ingredients are not as good as the medical VE VC! It is the highest and standard. (Vitamin B group should be mixed, not single.) )
The market, especially Amway, etc., are all big fools and cheat money. The content cannot be compared with the medical one.
It is still best to follow the doctor's instructions and use the medical VE VC.
*So far, there is no mature concept of how to take vitamins and minerals to nourish the human body. Especially for the intake of certain trace elements, no one can determine the most reasonable dosage. The biggest difficulty is that producers are unable to determine the age, gender, health status, and environment in which they live and work.
Moreover, it is not necessary for a healthy, non-picky young person to take a variety of vitamins for many years. Therefore, people should not spend their money on things that make no sense.
Many people even take vitamins every day, which is too much for a normal body! It disrupts the body's own absorption function. Those who eat a single vitamin are more likely to disrupt their own absorption balance. (Improper consumption is harmful to the human body).
Another example: eggs are a good thing, it is best to eat 1 2 per person per day. Why? You've got it, too.
Please consider the above.
