Brief Summary:
A. Anemia is a common problem affecting pregnancy and can result in profound consequences to both the mother and the growing fetus. Current treatment usually includes administration of oral or IV iron, or blood transfusions. Vitamin C is known to affect iron metabolism and has been shown to improve outcomes when used in addition to iron, however, few studies have been performed in pregnancy. The primary aim of this study is to identify the effects of vitamin C on anemia in pregnancy. The Investigators propose a double-blind, randomized placebo controlled trial of 1000mg vitamin C supplementation in 200 low risk pregnancies with iron-deficiency anemia. All newly enrolled patients, who meet inclusion and exclusion criteria, will receive the standard of care evaluation and treatment for anemia in pregnancy. Additionally, patients will be randomized to receive either placebo or vitamin C and compliance monitored with a pill diary. Data will be analyzed by T tests and Mann-Whitney U test. If the data shows a positive statistical significance, vitamin C may be a useful supplement to iron in treating anemia.
