That enzyme is called beta-glucuronidase. And one of the most-researched natural compounds for addressing it is calcium D-glucarate.

In this post, we'll break down exactly what calcium D-glucarate is, how it works at the biochemical level, what the research shows across multiple cancer types, and where it fits inside a comprehensive integrative oncology protocol.

What Is Calcium D-Glucarate?

Calcium D-glucarate is the calcium salt of D-glucaric acid — a naturally occurring compound produced in small amounts by the human body and found abundantly in a variety of plant foods. The calcium is there for stability in supplement form. The active ingredient is the glucarate portion.
