Study: Lion’s Mane Improves Cognitive Function in Older Adults
A 2009 study published in Phytotherapy Research conducted a clinical trial with older adults (50-80 years old) experiencing mild cognitive impairment to test the effects of Lion’s Mane supplementation.
Study Design
Japanese researchers administered Lion’s Mane tablets to participants for 16 weeks, then stopped supplementation for a 4-week washout period. Cognitive function was measured throughout using standardized assessments.
Key Findings
Cognitive function scores improved significantly during the 16 weeks of supplementation. Notably, scores decreased after participants stopped taking the supplement during the 4-week washout period, suggesting ongoing supplementation may be necessary to maintain benefits.
What This Reveals
This study suggests two important things: Lion’s Mane can support cognitive function in older adults with existing mild impairment, and the benefits may require ongoing supplementation rather than creating permanent changes.
Limitations to Consider
The study focused on older adults with existing mild cognitive impairment, so results may not directly translate to younger healthy populations. Individual responses vary, and more research is needed on optimal dosing and long-term effects.
