Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. (25)-D-Spirosta-3,5-Diene 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.
Fenugreek seed is a commercial source of steroidal sapogenins, and acid hydrolysis of its saponins generates diene by-products including this one. Supplements standardised to fenugreek sapogenins can therefore contain the diene as a processing artefact. The amount depends entirely on how aggressive the hydrolysis step was.
The compound is a non-polar steroid skeleton with no ionisable groups, so it dissolves in lipid and not in water. A medium chain triglyceride carrier keeps it in solution in a softgel and gives it a lipid phase to partition into in the gut. This is a delivery relationship rather than a biological one.
Phospholipid emulsifiers help disperse lipophilic sapogenin-derived material into mixed micelles. This is standard practice for any steroid skeleton with negligible aqueous solubility. It changes dispersion, and dispersion is not the same thing as a measured change in blood levels.
A conjugated 3,5-diene in a steroid ring is an oxidation-prone motif. Tocopherol is the usual lipid-phase antioxidant added to protect such structures in an oil fill during shelf life. The benefit is to the raw material in the capsule, not to the person taking it.
