Study
Mushroom Supplement May Improve Memory in Older Adults
Taking Yamabushitake mushroom supplements improved cognitive function in seniors with mild memory issues.
Summary
In plain language
A study found that seniors aged 50 to 80 with mild cognitive impairment experienced improved memory function after taking Yamabushitake mushroom supplements. Participants who took these supplements for 16 weeks showed better cognitive scores compared to those who took a placebo. However, the benefits decreased after stopping the supplement. This suggests that continuous intake may be necessary to maintain the positive effects. Importantly, no serious side effects were reported, making it a potentially safe option for those looking to support their cognitive health. Seniors interested in natural ways to boost memory might consider discussing this option with their healthcare providers.

The study was a double-blind, placebo-controlled trial involving 30 Japanese seniors with mild cognitive impairment. Participants were divided into two groups, one receiving the Yamabushitake supplement and the other a placebo, for 16 weeks.
Results showed that the group taking Yamabushitake had improved cognitive scores, which were measured using a specialized dementia scale.
After stopping the supplement, the benefits diminished, indicating the need for ongoing use for lasting effects.
No significant adverse effects were found, although some mild stomach discomfort was reported in both groups.
Seniors considering this supplement should talk to their healthcare providers to ensure it's a suitable choice for their health needs.

Research Quality Score
Scored October 22, 2026 using rubric mq-1.8_2026-07-06.
Assessment
The study's high score is due to its rigorous RCT design, which provides strong evidence for the intervention's efficacy. However, the lack of allocation concealment details, absence of a power calculation, and missing COI disclosure reduce the overall score. The study is relevant to the target population, but replication and transparency are areas for improvement.
