Cancer
"Calcium D-glucarate is not an essential nutrient, and thus no deficiency state exists."
Manufacturers of calcium D-glucarate recommend a daily intake of 200 to 400 mg.
"No side effects have been reported with calcium D-glucarate. Although there are no known drug interactions, many drugs (especially hormones) are metabolized in the liver by binding to glucuronic acid. It is therefore possible that taking calcium D-glucarate could increase the elimination of certain drugs or hormones from the body, thereby reducing their effectiveness. If you are taking any prescription medication, please consult your physician or pharmacist before taking calcium D-glucarate. At the time of writing, there were no well-known drug interactions with calcium D-glucarate."
