Another brilliant episode !! I wondered if you would consider doing an episode/discussing how to know what probiotics are recommended for different conditions. I have had my gallbladder removed and suffer with poor digestion and would love to hear more about what I can do to help digestion and possibly what probiotics are recommended for this. Thanks, Maria

Just found your podcast loving it so far, ATP science is my other favourite but they are also selling products so it is a little bit tainted in that way. your podcast is refreshing because you aren't trying to sell me anything. excepting maybe your guests or sponsors but there's no getting around that. thanks for the hard work love it. p.s. is it possible to have your patreon link in the description on castbox?
