Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Mustard 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.
Most broccoli sprout extracts are heat-processed, which destroys the plant's own myrosinase and leaves glucoraphanin sitting unconverted. Pairing with mustard seed powder restores the enzyme step outside the body. The measured result is more sulforaphane appearing in circulation from the same glucoraphanin dose.
Myrosinase activity is stimulated by ascorbate, which acts as a cofactor in glucosinolate hydrolysis. The effect is concentration dependent and has been characterised in enzyme kinetics work rather than in outcome trials. It is one reason glucosinolate conversion varies so much between preparations.
Selenium and sulfur move through overlapping uptake and assimilation routes in Brassica plants, so selenium fertilisation can shift the glucosinolate content of the crop. This is an agronomic effect that changes the raw material, not an interaction inside a person. It matters because it is one more reason two mustard batches are not the same.
Thiocyanate and related glucosinolate breakdown products compete with iodide at the sodium-iodide symporter in thyroid tissue. At ordinary culinary intakes with adequate iodine this is not a practical concern, but the competition is real and dose dependent. It matters most where iodine intake is already low and brassica intake is very high.
Sulforaphane generated from mustard-activated glucosinolates and curcumin are both described as electrophilic Nrf2 pathway activators in mechanistic work. Combining them is a formulation convention rather than a tested pairing. No human trial has compared the combination against either alone.
Piperine is added to many botanical blends on the basis of its effect on phase two conjugation enzymes. Sulforaphane is cleared largely through the mercapturic acid pathway, so any piperine effect on its kinetics is plausible but untested. This is formulation practice, not a demonstrated pairing.
Cold-pressed mustard seed oil carries native tocopherols that slow oxidation of its own unsaturated fatty acids. It is also high in erucic acid, which is why food-grade use is restricted in several jurisdictions and why low-erucic cultivars exist. The oil fraction and the glucosinolate fraction are separate products with separate considerations.

2 sources behind our Mustard 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 282 voluntary, unverified reactions reported to the FDA (openFDA). The number mostly reflects how popular Mustard is, not how risky it is. A report is not proof Mustard caused anything. It is a signal of what to watch for, nothing more.
