"In addition to being a powerhouse in the immunity department to help fight off infections and keep your skin healthy and wounds healing, vitamin C also acts to help increase your absorption of iron, another nutrient as you recall that is especially important during pregnancy," says Shaw. "The RDA for vitamin C is 85 mg per day during pregnancy." There are many places to get this nutrient, as it's in most colorful fruits and vegetables, such as citrus, bell peppers, kiwi, strawberries, and broccoli.
