In episode 30, I talk about the use of zinc lozenges to fight colds. While nutritional zinc does support the immune system and your immunity may benefit from zinc supplements or zinc-rich foods, this has nothing to do with the use of zinc lozenges to kill colds. The science behind their use is strong, but it also suggests that most of the dozens of zinc lozenges on the market are absolutely useless. The only ones I currently use and recommend are Life Extension Enhanced Zinc Lozenges. Listen in to find out why!
