The team asked 72 Japanese volunteers between the ages of 60 and 80 to take either a wasabi tablet (containing 0.8 milligrams of 6-MSITC) or a placebo tablet every night before going to bed for 12 weeks. The researchers screened out people with known ailments, mental disorders, memory problems and those taking certain medications or who were heavy drinkers.
Each volunteer was also asked to take cognitive and memory tests before and after the test period.
The test results showed that the volunteers who took the wasabi tablets exhibited improvements in both long- and short-term memory but experienced no changes in cognitive ability. The researchers also found that those taking the wasabi tablets did better on association tests, such as connecting names to faces, which prior research has shown is a common problem in aging adults. The volunteers who were given a placebo showed no memory or cognitive improvements, however.

The above is a way better clinical trial than the highly questionable 20 person “Prevagen” endeavor that has become infamous.
