Primary

Reduces bacterial adhesion to urothelium

A-type proanthocyanidins change the joining of E. coli fimbriae to epithelial receptors so bacteria have a harder time holding on the bladder wall. People with repeated urgency and a still-incomplete feel after voiding more often see change in interval between episodes and voiding comfort after several continuous weeks.

Primary

Helps the mouth reduce biofilm attachment

The same class of proanthocyanidins in oral trials also watches bacterial attachment to tooth surface and mucosa; biofilm formation is often slower. People whose tooth surfaces feel sticky after meals and whose gum margins are sensitive more often see a difference in oral freshness and gum comfort after several continuous weeks.
