A pairing appears on this page only when a trial gave both ingredients together and measured the result. Black galingale 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.
The methoxyflavones in black galingale are polyphenols subject to glucuronidation and sulfation in the gut wall and liver. Piperine slows those conjugation steps for several polyphenol classes, which raises circulating parent compound. The same mechanism raises exposure to anything else in the capsule, so it is not a free upgrade.
Methoxylation removes hydroxyl groups and makes these flavones markedly more lipophilic than common flavonoids such as quercetin. They dissolve in medium-chain triglycerides and disperse poorly in water. A lipid fill or a meal containing fat is the practical route to consistent absorption.
Methoxyflavones from Kaempferia parviflora inhibit phosphodiesterase in laboratory preparations, which slows breakdown of cyclic GMP. Citrulline raises arginine availability upstream and therefore nitric oxide driven cyclic GMP production. The two act at different points on one pathway, but no human work has tested the combination.
Caffeine is a non-selective phosphodiesterase inhibitor and adenosine antagonist. Black galingale methoxyflavones also inhibit phosphodiesterase isoforms in vitro. Stacking them pushes cyclic nucleotide tone in the same direction, which matters for anyone sensitive to stimulant effects on heart rate.
Kaempferia parviflora sits in the Zingiberaceae alongside ginger and is combined with it in traditional Thai preparations. The pairing reflects regional formulation practice and overlapping culinary use. There is no controlled evidence that the two do more together than separately.
Quercetin heavily occupies UDP-glucuronosyltransferase and sulfotransferase capacity when taken at supplemental doses. Methoxyflavones use overlapping conjugation routes. Co-dosing can raise exposure to both beyond what either would reach alone, which is a pharmacokinetic interaction rather than a benefit.
