The normal recommended amount of vitamin c is 1,000 milligrams(mg) per day for non-pregnant woman. During pregnancy, how much Vitamin C does a pregnant woman need?

Answer 1

There are maximum and minumum recommended daily amounts. Both are discussed here:

What you call the "normal" amount is about half the recommended maximum, and much more than the minimum.

Beware of taking too much; it can cause scurvy in the newborn baby after birth.
