The musculoskeletal function of vitamin D has been well defined, prompting the population to supplement with vitamin D and calcium to maximise bone growth. However the role of vitamin D in pregnancy has not been systematically studied and is permeated with continuing controversy regarding the cause and effect relationship of vitamin D and pregnancy outcomes. Although further research is needed, the National Institute of Health and Clinical Excellence (NICE) (2008) recommend that all pregnant and breastfeeding women supplement with 10 microgrammes of vitamin D daily. Furthermore midwives and health visitors are asked to educate women about the importance of vitamin D supplementation, at booking and throughout antenatal care. Each appointment presents an opportunity to address concerns and explore options to increase levels through diet and supplementation and address any difficulties in obtaining supplements.
