Internet influencers have been pushing “immune boosters” during the pandemic — claiming they’ve got just the pill, berry or brew to rev up our body’s defenses. But is there really a way to boost our immune system? We’re finding out whether these vitamins and supplements truly work as a shield against colds and viruses. We speak to public health Prof. Tim Caulfield, nutrition Prof. Carol Johnston, immunologist Shiv Pillai, and immune aging researcher Niharika Duggal.  UPDATE 3/12/21: An earlier version of this episode overstated the evidence that starting to exercise leads to fewer colds and flus. While we do have lots of evidence that suggests exercise is good for our immune system, the research around starting an exercise program is more mixed. We've updated the episode.
