A dietary supplement given to pregnant women at high risk of pre-eclampsia can reduce the likelihood of the disease occurring, a study says.
Writing in the British Medical Journal, researchers says the presence of an amino acid and antioxidant vitamins in the supplement helps to combat abnormally high blood pressure. More than 600 women took part in the study in Mexico City. But experts say more research is needed on the effects of the supplement.
Pre-eclampsia is a serious condition where abnormally high blood pressure and other problems develop during pregnancy. It affects up to 10% of all first-time pregnancies and is dangerous for both mother and child. Pre-eclampsia is thought to be linked to a deficiency in L-arginine, an amino acid that helps maintain a healthy blood flow.
