God I hate being sick. Truly.

I would smoke a handful of Bill Clinton’s cigars if it meant never getting sick again.

Unfortunately, I don’t think I’ll ever get an invite to the DC spirit cooking parties, so I’ll have to accept the fact that getting sick is just part of my abject existence as a lowly human.

That doesn’t mean I can’t do things to help prevent sickness and reduce the duration and severity when it strikes, and that’s why I got the co-founder and former lead researcher and writer of, as well as the Director of Research for my supplement company, Legion Athletics, Kurtis Frank to come on the show and talk immunity.

As you’ll discover, this is a muddy topic with a lot of bad research and bad interpretations of research, but Kurtis has spent hundreds of hours reading through dozens and dozens of papers, and in this podcast, he breaks down his findings.

So … if you’ve wondered what supplements do and don’t work for improving your immune function, and if changing your diet can really help you get sick less often or recover from illnesses faster, then you want to listen to this show.
