The Verdict

All 5 experts agree that gut microbiome health is foundational to longevity, immunity, and brain function. The strongest consensus is around fermented foods over probiotic supplements. Huberman recommends 4 servings of low-sugar fermented foods daily as the primary intervention. Attia takes a science-forward approach, personally using Pendulum Akkermansia and AG1 while emphasizing that the probiotic market is largely unregulated. Patrick highlights the Sonnenburg research showing fermented foods increase microbial diversity and reduce inflammatory markers. Hyman is the most prolific advocate, outlining a comprehensive 5R gut-healing protocol and recommending probiotics as one of his foundational supplements. Johnson includes fermented foods in his daily Blueprint meals.
