Gut Microbiome Research — The Longevity Connection
Gut diversity collapses with age. The strains that drive the collapse — and the protocols that reverse it.
Microbiome diversity is one of the most consistent biological correlates of healthspan in centenarian cohort data. The published comparisons between centenarian gut composition and average 60-year-old composition show systematic shifts — falling Akkermansia muciniphila, falling SCFA-producing Bifidobacterium and Faecalibacterium prausnitzii, rising pro-inflammatory Enterobacteriaceae.
The intervention literature has identified specific strains that reverse those shifts. The Stanford/Sonnenburg work on gut barrier integrity, the Cani et al. work on Akkermansia and metabolic health, and the broader probiotic intervention literature all converge on a small set of strains delivered at the 10–50 billion CFU dose range. Strain identification matters — L. rhamnosus GG behaves differently from L. rhamnosus HN001, and only one of them was used in the specific trial you're trying to replicate.
The protocols, the strains, the dose-response, and the supplements built on the literature follow.
