Kiwifruit shows neuroprotective properties in laboratory cells and animal brains, but no human clinical trials or Alzheimer's evidence exist—making current claims overstated.

Rooibos tea shows neuroprotection in lab studies, but lacks human clinical evidence and brain bioavailability data needed to claim Alzheimer's prevention.

Animal studies suggest apigenin may help Alzheimer's disease, but no human trials exist, and bioavailability limits make translation unlikely.

Urolithin A shows promise in mouse brains but lacks human evidence for Alzheimer's; a Phase 2 trial is underway to test whether early-stage benefit translates to people.

The recent animal research is legitimately encouraging and has attracted serious attention from Alzheimer's researchers, but the jump from rodent reversal...

Cabbage shows theoretical promise against Alzheimer's in lab models, but no large human trials have tested it—the only study used people with memory impairment, not Alzheimer's.

The largest trial found no cognitive benefit from cocoa flavanols overall; gains appeared only in people with very poor baseline diet quality, and no trial has shown dementia prevention.

Sage extract showed promise in small trials but home-brewed tea lacks therapeutic doses; drug trials have failed, and long-term evidence remains absent.
