Activated Cranberry
From PACs to bioactive metabolites: understanding cranberry's role in urinary tract health
Cranberry science has changed. Early theories said cranberry acidified the urine. Later research identified A-type proanthocyanidins (PACs) and their effect on bacterial adhesion. The newest evidence suggests the gut microbiome transforms cranberry polyphenols into smaller metabolites that appear in urine.
This short deep dive traces that shift, explains why PAC dose and whole-cranberry composition matter, and summarises the human clinical evidence for a cranberry phytosome.
