Why this page doesn't claim "Cranberry works"
Whole foods almost never have RCTs — the evidence sits on the ingredients. So this page does one honest thing: it lists which graded ingredients Cranberry contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Cranberry itself.
Bottom line: Cranberry's key point is the proanthocyanidins that prevent urinary tract infections, but reaching the studied dose (about 36 mg PAC) requires concentrated juice or pure product - diluted juice is often not enough.
