Overview

TUDCA is a naturally occurring bile acid that plays a crucial role in neutralizing toxic bile acids in the liver. It is highly effective at protecting liver cells from stress, reducing apoptosis (cell death), and improving bile flow, making it a cornerstone supplement for liver detoxification and cholestasis.

Key Benefits

Reduces Liver Enzymes

Clinically shown to significantly lower elevated liver enzymes such as ALT and AST, indicating improved liver health.

Improves Bile Flow

Helps to thin bile and improve its flow, which is crucial for digestion and the elimination of toxins.

Protects Liver Cells

Acts as a chemical chaperone to reduce endoplasmic reticulum (ER) stress, a key factor in liver cell death.

Neuroprotective Effects

Research suggests TUDCA may protect neurons from cell death, showing potential in neurodegenerative diseases.
