A recent double-blinded trial published in Nutrients demonstrated clinically that supplements containing wasabi's key bioactive component, 6-MSITC (6-Methylsulfinylhexly isothiocyanate), improved memory and recall ability in adults aged 60 and over.1 While the 75 older participants took either a 100mg 6-MSITC extract powder or a placebo pill for 12 weeks, those assigned the wasabi derivative experienced enhanced episodic and working memory. Specific neurological testing showed significant benefits on the logical memory and digit span tests that involve memorizing stories and number sequences.
