Gut Health
Your gut is a 30-foot chemical plant staffed by roughly 38 trillion microbes, and it touches nearly everything — digestion, immunity, mood, even how you age. This section gathers the whole story in one place: interactive animations of digestion you can watch and break on purpose, the microbiome and probiotics, the fermented foods that feed it, the digestive conditions from reflux to SIBO to IBD, and the supports and practices — from betaine HCl to elimination diets — with an honest reading of the evidence for each.
