Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
Calcium D-glucarate is used to support beta-glucuronidase inhibition and Phase II detox / estrogen clearance (Walaszek 1990). Preliminary human evidence exists for hormone-related conditions but RCTs are limited. Typical effective dose 1,500-3,000mg. Upper Standard tier — mechanistically interesting, evidence still emerging. Would move to Verified with disclosed dose alignment and RCT data.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

Calcium D-glucarate is used to support beta-glucuronidase inhibition and Phase II detox / estrogen clearance (Walaszek 1990). Preliminary human evidence exists for hormone-related conditions but RCTs are limited. Typical effective dose 1,500-3,000mg. Upper Standard tier — mechanistically interesting, evidence still emerging. Would move to Verified with disclosed dose alignment and RCT data.
Strongest: Formulation at 68/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 65/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Safety at 62/100 (adverse-event profile, interaction risk, and dose ceiling) and Sustainability at 50/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
Would move to Verified with disclosed dose alignment and RCT data.

Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
