Calcium D-glucarate is the calcium salt of D-glucaric acid, a natural substance found in many fruits and vegetables.
Where is it found?
Calcium D-glucarate is available in capsules and tablets. Foods high in glucaric acid (a form of calcium D-glucarate) include apples, Brussels sprouts, broccoli, cabbage, and bean sprouts.1
Calcium D-glucarate has been used in connection with the following conditions (refer to the individual health concern for complete information):
| Science Ratings | Health Concerns |
|---|---|

|
 Reliable
and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies
suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal
or no scientific evidence. For a supplement, little scientific support and/or minimal health
benefit. |

Who is likely to be deficient?
Calcium D-glucarate is not an essential nutrient, and thus no deficiency state exists.
How much is usually taken?
Manufacturers of calcium D-glucarate recommend a daily intake of 200 to 400 mg.
Are there any side effects or interactions?
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.
