Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Albizia 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.
Albizia bark and leaf preparations carry condensed tannins, and tannins bind divalent metal cations in the gut lumen. Zinc taken in the same dose window can end up partly bound and less available for uptake. Separating the two by two hours removes most of the overlap. This is chemistry of the extract, not a property specific to this genus.
Non-heme iron is the classic casualty of dietary tannins. Polyphenol hydroxyl groups form insoluble complexes with ferric iron, which cuts absorption at that meal. Anyone taking iron for low iron status should keep tannin-rich botanical extracts at a distance in the day. The effect is on that dose, not on total body stores over time.
Ascorbic acid reduces ferric iron to the ferrous form and keeps it soluble, which partly offsets the binding effect of tannins in the same meal. In formulations that pair a tannin-rich botanical with iron, ascorbate is the usual counterweight. It blunts the interference rather than removing it.
Albizia julibrissin bark and flower have a long place in traditional calming preparations, and modern blends often set it alongside theanine for the same intended feel. There is no human trial of the pairing. Read it as formulation convention rather than a demonstrated combined effect.
Evening formulas frequently place albizia with magnesium because both are sold into the same wind-down context. No controlled work has tested them together in people. The pairing is formulation practice, and any subjective effect cannot be assigned to either component from current data.
Condensed tannins bind proteins non-specifically, and supplemental proteases and amylases are proteins. Taken in the same capsule window, a tannin-rich botanical can reduce measured enzyme activity in the gut lumen. Formulators generally separate the two. This is an in-vitro and feed-science observation carried into supplement practice.
