Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Clitoria ternatea 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.
Ternatins, the polyacylated anthocyanins that give butterfly pea its blue colour, hold up well at low pH but degrade faster when ascorbic acid is present in solution. The two react over storage, so a co-formulated drink tends to fade toward brown sooner than either ingredient alone would predict. This is a colour and stability issue, not a toxicity one. Formulators usually separate the two or accept a shorter shelf window.
Butterfly pea flower infusions carry flavonols and tannin-type polyphenols that bind non-haem iron in the gut lumen and lower its absorption. The effect is the same one seen with tea and coffee taken at a meal. Anyone taking an iron supplement is better served spacing the flower tea a couple of hours away from the dose. Haem iron from meat is much less affected.
Clitoria ternatea extract contains kaempferol and quercetin glycosides alongside its anthocyanins, so a quercetin supplement sits on the same chemical family rather than adding a new one. In assay conditions the radical-scavenging contributions add up. Whether that translates to anything measurable in a person has not been shown. Read the pairing as chemical overlap, not as a demonstrated combined benefit.
Polyphenols from butterfly pea flower slow alpha-amylase and alpha-glucosidase in vitro, and catechins do the same through the same binding mode. Combining them raises total inhibitory polyphenol in the gut lumen. Enzyme inhibition in a test tube is a marker, not an outcome, and the dose that reaches the small intestine after a beverage is far lower than assay concentrations. Read it as mechanistic rather than clinical.
Anthocyanin extracts are hygroscopic and clump badly on their own, so they are usually spray-dried onto a carbohydrate carrier such as inulin or maltodextrin. Inulin does the job and also passes through undigested to the colon. The pairing is formulation convention. It changes handling and flow, not the pigment's biology.

1 source behind our Clitoria ternatea verdict: peer-reviewed studies and registered clinical trials. Every one links straight to PubMed, the journal, or ClinicalTrials.gov. Read them yourself.
Evidence surfaced via Semantic Scholar (Allen Institute for AI) and ClinicalTrials.gov. Ranked by study type and citation weight, not cherry-picked.
Read this carefully. These are 286 voluntary, unverified reactions reported to the FDA (openFDA). The number mostly reflects how popular Clitoria ternatea is, not how risky it is. A report is not proof Clitoria ternatea caused anything. It is a signal of what to watch for, nothing more.
