1. The recommended intake of vitamin C for adult and early pregnant women is 100mg/d

2. The recommended intake of vitamin C in middle and late pregnant women and nursing mothers is 130mg/d.

Note: The individual differences in the demand for VCs from each person are significant.

Some people can be satisfied with small amounts, and some people can reach 10 grams or more per day.

In the history of human vitamin C research, Dr. Robert F. Cathcart discovered and established a standard for the use of vitamin C as early as the 1970s.

When a person takes oral vitamin C to a considerable amount, that is, 0.5 to 200 g for 24 hours, slight diarrhea may occur due to a change in intestinal osmotic pressure. Cascutt's amount below this is called "vitamin C's intestinal tolerance," which is the amount that one can afford without causing mild diarrhea.

Because there is no acid VC, making a lot of oral vitamin C possible, then everyone can take according to their own body condition. As long as it is within the tolerance of your own intestine, the effect will be very good.

Interestingly, the body's tolerance to VC is variable. When the human body is sick, the intestinal tolerance will be greatly increased. For example, a tolerance of 1 gram per day will be different in cases of acute infection or chronic diseases such as cancer or heart disease, or even colds. The degree of tolerance increases.
