Hi, Thanks for asking. I understand your concern. - MSG is a flavor enhancer added to Chinese food. It is described as generally safe product.. as it has few temporary side effects like nausea, head ache,weakness, tingling on face, flushing rapid heart beat. these symptoms usually do not persist. But it is advisable to avoid routine intake of MSG. ..specially in pregnancy when we are concerned about baby. taking it for a couple of times would not have permanent bad effect.. pl. don t worry.. but avoid it in future. - Flex seeds have very essential nutrient 9 omega 3 fatty acid ). It is essential for fetal growth / Alos flex seeds contain good fibers & vitamins. SO you should take flex seeds in pregnancy.. in optimum quantity ( 1 tea spoon powder) / in form of flex seed oil daily. Thanks.
