Royal College of Obstetricians and Gynaecologists in un recente documento (Giugno 2014) ha sottolineato l’importanza della supplementazione di Vitamina D in gravidanza.

Recenti studi hanno rilevato il ruolo di Vitamina D nel favorire della secrezione e azione dell'insulina, modulazione immune e lo sviluppo del polmone. Ha quindi il potenziale di influenzare molti fattori nel feto in via di sviluppo.

Questo documento indaga gli effetti della vitamina D nell'unità feto-placentare e la madre. Ci sono poche informazioni sull'assunzione di vitamina D in gravidanza e allattamento e pochi studi sui risultati clinici. Questo documento fornisce un parere circa supplementazione e trattamento.

La mancanza di vitamina D nelle donne in gravidanza è stata associata a diabete, preeclampsia, aumento del tasso di taglio cesareo, mentre i bambini possono essere più piccoli (SGA: piccolo per età gestazionale). può provocare rachitismo e malattie alle ossa e ipocalcemia.

La più grande fonte di vitamina D negli adulti è sintesi dalla radiazione solare; mezz'ora di sole offre circa 50000 UI di vitamina D.

Le due forme principali sono la vitamina D3 (Colecalciferolo), che deriva principalmente dalla luce del sole, e D2 (ergocalciferolo) che si trova in alcuni alimenti.
