Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Java Tea has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
An increase in urine flow carries electrolytes with it. The magnitude with Java tea specifically has not been quantified in controlled human work, so this is a mechanistic expectation from the aquaretic effect rather than a measured depletion. It matters most for anyone already on a prescription diuretic, where the two effects stack. That combination is a conversation for a clinician, not a formulation decision.
Renal magnesium handling is flow-sensitive, so the direction is predictable from physiology. No human measurement exists for this plant. Read the pairing as a reason to keep magnesium intake adequate during extended use, not as evidence that Java tea causes deficiency.
This is a compensatory pairing rather than a synergy in the usual sense. It is standard practice around any aquaretic or diuretic ingredient. It does nothing to the plant's own action, it addresses the predictable consequence of that action.
Rosmarinic acid is the overlap, and it is the compound most often cited for the antioxidant activity of either plant. Additivity here is arithmetic on a shared molecule. Both are hydrolysed by gut microbes to caffeic acid and downstream metabolites before absorption, so the shared route continues past the gut wall.
Two ingredients pushing urine flow in the same direction will add. Dandelion is notable for carrying substantial potassium itself, which partially offsets the electrolyte loss both cause. The pairing is well established in traditional practice and thin on controlled human data.
Conjugating capacity is finite and shared. At concentrated extract doses of both, circulating levels of each may run higher than either alone predicts. Green tea also brings caffeine, which has its own mild diuretic effect that adds to the aquaretic action. Worth naming rather than regarding as a problem.
Long combined use in the same category, with the same electrolyte caveat applying to the pair as to either alone. Both are monographed by European herbal assessment bodies on the basis of traditional use, which is a real but limited grade of evidence and should be described as exactly that.
