Calcium-D-glucarate
Detox · Beta-glucuronidase inhibitor
Tier C+
Bottom line
Read Off Label grades Calcium-D-glucarate as C+ (5.4/10) based on weak evidence, weak benefit magnitude, and a low-risk safety profile.
Rationale is real — gut β-glucuronidase activity does influence reabsorption of conjugated hormones and xenobiotics.
Typical use: 500-1500 mg/day PO — OTC.
What this is
Rationale is real — gut β-glucuronidase activity does influence reabsorption of conjugated hormones and xenobiotics. But clinical outcome data in humans is thin. Popular in 'estrogen detox' protocols around women's health and hormone rebalancing. Reasonable low-risk adjunct but not a clinical standard.
Mechanism
Metabolite of glucaric acid; inhibits β-glucuronidase — an enzyme produced by gut bacteria that deconjugates glucuronidated compounds (hormones, toxins) in the gut, allowing their reabsorption
Dose & route
500-1500 mg/day PO
