Why this page doesn't claim "Guava 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 Guava contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Guava itself.
Bottom line: Guava is the king of natural vitamin C (one serving is several times the daily requirement); its other components are everyday amounts.
