Review finds promising but limited evidence on mushroom compound and brain health
Researchers at the University of Rzeszow in Poland reviewed studies of ergothioneine, an antioxidant found in mushrooms and other foods.
The review examined whether the compound might help protect the brain from diseases that affect memory and movement as people age.
Some studies found that lower blood levels were linked to poorer cognition or higher disease risk, but these links do not show that low levels cause illness.
Findings were not consistent, and the review notes that higher levels were linked to increased Alzheimer’s risk in one study.
Experiments in cells and animals found protective effects, but some used doses higher than people typically get from food.
Human evidence remains limited: short-term supplementation showed nonsignificant downward trends in some markers of inflammation and oxidative damage, while the available account gives no full results for a 16-week study.
Researchers at the University of Rzeszow reviewed evidence on ergothioneine, a compound found in mushrooms and other foods, and its possible effects on brain health.
Some observational studies link lower blood levels of ergothioneine with poorer cognition or neurodegenerative disease.
Cell and animal studies report protective effects, but often used doses higher than typical dietary intake.
Human studies described in the review provide limited evidence, and associations do not show whether low ergothioneine contributes to disease or results from it.
The review also notes conflicting findings, including one study linking higher ergothioneine levels with increased Alzheimer’s disease risk.
