*2.1.3 Pregnancy and lactation*

The RDA in the US and Canada for pregnant mothers is usually doubled (up to 85 mg/day) and is tripled during lactation [5, 22]. This is probably due to the high turnover of vitamin C, increasing the need for vitamin C by the developing fetus and suckling infants and hemodilution in pregnancy [23]. In fact, complications associated with pregnancy are significantly reduced by vitamin C intake [24]. That is why the RDA is higher in these groups of people.
