Taking vitamin D in pregnancy protect babies from asthma

Taking vitamin D supplements in pregnancy strengthens babies’ immune systems, which may lower their risk of developing asthma, new research reveals.
The unborn babies of expectant mothers who take more than the recommended daily vitamin D dose for pregnant women respond better when exposed to simulated pathogens, a study found.
Previous studies have demonstrated a link between a strong immune system in early life and a reduced risk of asthma.
Researchers believe this may also extend to greater respiratory health overall.
Lead researcher Professor Catherine Hawrylowicz, from King’s College London , said: ‘For the first time, we have shown that higher vitamin D levels in pregnancy can effectively alter the immune response of the newborn baby, which could help to protect the child from developing asthma.’
