On this topic as well. I have had the worst luck in this pregnancy - I have had recent exposures to cold sores (which I have no immunity to), flu, a person with a stubborn chest infection and potential exposure to MRSA - I am so over sick people who seem to be out to infect me at the moment!!!! Anyone know of any safe supplements you can take in pregnancy to boost immunity?? My naturopath has me on extra zinc, extra vitamin C, and lysine for the cold sore exposure - but with the amount of infections Ive been near now, I am worried it wont be enough! Im on strong probiotics so hoping they will help..
