Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Red rice 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 mevalonate pathway branches: one arm makes cholesterol, the other makes the isoprenoid tail of ubiquinone. Blocking HMG-CoA reductase reduces flux to both arms, which is why serum CoQ10 falls alongside cholesterol. Co-supplementing CoQ10 is standard formulation practice for this reason, though whether it changes how people feel is a separate question.
The same isoprenoid pool that supplies ubiquinone also supplies the polyprenyl side chain of menaquinones. Reduced mevalonate flux therefore has a theoretical downstream effect here as well. The evidence for this is mechanistic rather than clinical, so it is worth flagging in formulation, not asserting as an outcome.
Both are fermentation products used together in blends aimed at circulatory markers, and recent trial commentary has examined the combination directly. The pairing is a formulation convention with emerging human data behind it. Anyone on anticoagulant or antiplatelet medication needs medical supervision here because the fibrinolytic side adds to that effect.
Pigmented rice varieties carry proanthocyanidins and anthocyanins in the bran layer, chemically close to what grape seed provides. Combining them raises total polyphenol intake without adding a new mechanism. This is additive chemistry, and the human evidence for the combination specifically is thin.
Phytic acid in the bran layer of whole and pigmented rice chelates iron, zinc and calcium into complexes the small intestine cannot absorb. Milling removes bran and removes much of the phytate along with the pigment. Separating a mineral dose from a bran-containing rice product by an hour or two sidesteps most of this.
Zinc is arguably the mineral most affected by phytate, and the molar phytate to zinc ratio of a meal predicts absorption reasonably well. Whole pigmented rice therefore lowers zinc availability relative to polished rice. Phytase, soaking or fermentation each cut the phytate load.
Phytase cleaves inositol hexaphosphate stepwise, and mineral binding weakens sharply once several phosphates are gone. Adding phytase, or fermenting the grain so microbial phytase does the work, restores much of the iron and zinc availability. This is why fermented rice preparations differ from raw bran on mineral handling.
Rice bran arabinoxylan is fermented in the colon, and the accompanying microbial ecology shapes what metabolites result. Work in poultry has combined fermented red mold rice with probiotics and reported changes in cholesterol handling. That is an animal finding, so read it as a mechanism worth studying rather than a human result.

1 source behind our Red rice 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 452 voluntary, unverified reactions reported to the FDA (openFDA). The number mostly reflects how popular Red rice is, not how risky it is. A report is not proof Red rice caused anything. It is a signal of what to watch for, nothing more.
