Infants whose mothers took DHA supplements during pregnancy had fewer colds and shorter illnesses at one, three, and six months of age, a new study finds. “This is a large scale, robust study that underscores the importance of good nutrition during pregnancy,” says Usha Ramakrishnan, associate professor in the global health department at Emory University. “Our findings indicate that pregnant women taking 400 mg of DHA are more likely to deliver healthier infants.”
