Info: In Development

Tauroursodeoxycholic acid or TUDCA is a naturally-occurring bile salt. It's available in some markets as nutritional support for a variety of health concerns including healthy liver function and certain neurodegenerative and neurological disorders. There are TUDCA supplements in development at this time, but none that have been licensed and approved for sale by Health Canada are widely available.

Product Notes:

Why is it not available? I've seen TUDCA supplements for sale in Canada.

While it may be available from some sellers, most TUDCA formulas available online are not approved for sale here. You may notice that they don't have bilingual Canadian packaging. These products are most often shipped directly from the USA.

Naming Note: For simplicity, TUDCA is frequently used as a term for Tauroursodeoxycholic acid which can also be represented in its even more complex long form: 2-[[(3alpha,5beta,7beta)-3,7-Dihydroxy-24-oxocholan-24-yl]amino]ethanesulfonic acid.
