TUDCA (Tauroursodeoxycholic Acid) for Alzheimer's Disease
Also known as: Tauroursodeoxycholic acid, Taurursodiol
TUDCA's ER stress reduction and anti-apoptotic properties may protect neurons from amyloid-induced toxicity.
Mechanism of Action
In Alzheimer's, TUDCA reduces ER stress triggered by amyloid-beta accumulation, decreases caspase activation, and improves mitochondrial function in hippocampal neurons. Preclinical models show reduced amyloid pathology and improved cognitive function.
General mechanism: Bile acid with anti-apoptotic (mitochondrial stabilization) and chemical chaperone (ER stress reduction) properties.
Current Evidence
Preclinical evidence is strong. Human studies are limited to case reports and small pilot trials. Combination with other neuroprotective agents is being explored.
Clinical Status: Preclinical for Alzheimer's specifically. Available as supplement.
Safety Profile
Very well-tolerated. Mild GI effects at high doses. Long history of safe use as a supplement and in bile acid replacement.
Key Research Questions
- Can TUDCA slow amyloid-related neuronal loss in early Alzheimer's?
- What is the synergy potential with anti-amyloid antibodies?
