02 Jun 2020 --- Pregnant women who consume extra choline supplements may decrease the negative impact that viral respiratory infections, including COVID-19, can have on their babies. This is according to a new study from the University of Colorado Anschutz Medical Campus in the US. The researchers highlight that supplementation with choline, which is linked to boosting brain health, is more relevant now than ever. This is due to the negative effects that the novel coronavirus may have on fetuses’ brain development, leading to mental health issues.
