5. Conclusions
6-MSITC is the main bioactive compound of wasabi. We investigated the benefits of 6-MSITC intake on cognitive health in older adults. The current RCT revealed that an intake of 0.8 mg of 6-MSITC for 12 weeks significantly improved memory functioning, including episodic and working memory, compared to the placebo group, but we did not find any significant improvements in other cognitive functions. This study is the first to demonstrate that 6-MSITC has a benefit on memory functioning in healthy older adults.
