GDAid

GDAid is a product from BioStack, categorized under Weight management & metabolic health in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

65/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Formulation 72, Evidence 68, Safety 68, Manufacturing 62, Transparency 60, Sustainability 50. Scored as of 2026-08-24.

BioStack GDAid — glucose disposal agent (GDA) category product. Typical GDA formulations stack berberine + chromium + banaba (corosolic acid) + R-lipoic acid + cinnamon + gymnema — each with modest independent glucose-modulation evidence. BioStack is an established longevity/performance-focused brand with real formulation research investment. Held below Verified by (1) per-active mg breakdown not disclosed at product name — for combo GDA products this is essential since each active has its own dose-response curve (berberine studied at 500mg TID, chromium at 200-1000mcg, R-ALA at 300-600mg, banaba at 24mg corosolic acid); (2) 'GDAid' branding is bodybuilding-context marketing rather than clinical positioning; (3) no third-party assay. Would move to Verified 70+ with per-active mg breakdown + third-party COA + honest positioning.

Strongest: Formulation at 72/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 68/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Transparency at 60/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) 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 70+ with per-active mg breakdown + third-party COA + honest positioning.

The Vyvata Scoring Framework rates every listed product 0–100 across six dimensions: Evidence, Formulation, Manufacturing, Safety, Transparency, and Sustainability. 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.
