BioWizdom Berberine & Oregon Grape Tincture 2 oz Bottle

BioWizdom Berberine & Oregon Grape Tincture 2 oz Bottle is a product from BioWizdom, 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.

58/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Formulation 65, Safety 65, Evidence 62, Transparency 58, Manufacturing 55, Sustainability 55. Scored as of 2026-08-24.

BioWizdom Berberine + Oregon Grape (Mahonia aquifolium) tincture. Oregon grape is a legitimate secondary source of berberine + related isoquinoline alkaloids (berbamine, oxyacanthine). Traditional-medicine background for the combo. Tincture (alcohol extract) is unusual for berberine — most RCT literature uses standardized capsule berberine HCl at 500mg TID doses; tincture dosing is much harder to standardize. Held below Verified by (1) berberine content per mL not disclosed at product name — essential for liquid extracts; (2) tincture format is difficult to reach studied 500-1500mg/day therapeutic doses (typical tincture 1-2 mL = maybe 50-100mg berberine); (3) small brand; (4) no third-party assay. Would move to Verified 70+ with per-mL berberine content disclosure + third-party assay + honest positioning of tincture doses relative to studied capsule protocols.

Strongest: Formulation at 65/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Safety at 65/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status) and Sustainability at 55/100 (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-mL berberine content disclosure + third-party assay + honest positioning of tincture doses relative to studied capsule protocols.
