Yukiguni Factory Co., Ltd. conducted joint research with Kobe Pharmaceutical University and Kato Hospital, revealing for the first time that eating Maitake mushrooms can improve cognitive function in healthy older adults. A randomized, double-blind, placebo-controlled trial on 47 healthy Japanese older adults (aged 60-85) was conducted over 18 weeks. Participants ingesting 50g of Maitake Y10M strain daily showed improved cognitive function and activation of natural killer (NK) immune cells, correlating with cognitive improvement. Conversely, the Maitake C5304 strain showed no significant changes. The results suggest daily Maitake consumption may help maintain cognitive function via the immune system and reduce dementia risk. The findings were published in the 'Journal of Nutritional Science and Vitaminology' on April 30, 2026 (Jogi et al.).
