Curcumin for Age-Related Cognitive Decline
B Good Evidence At least one randomized trial supports this, with mostly consistent results.A UCLA 18-month RCT found bioavailable curcumin improved memory test performance and reduced brain amyloid/tau PET signals in non-demented adults. Bioavailability of the formulation is the key factor for effectiveness.
The Bottom Line
A UCLA 18-month RCT found bioavailable curcumin improved memory test performance and reduced brain amyloid/tau PET signals in non-demented adults. Bioavailability of the formulation is the key factor for effectiveness.
