11. Wedderspoon Manuka Honey Immunity Lozenges
So here’s the thing: A strong immune system depends on a lot of factors, including how you eat and sleep, exercise and manage stress, and simply taking a cough drop with ingredients that have been shown to be supportive of immune function will not speed your cold or cough away. That said, these lozenges contain vitamin C and zinc, both of which you need enough of to keep your immune system functioning optimally. Plus they taste great and coat your throat, which helps a cough relax.
