Thorne Berberine Dietary Supplement 1000 mg 60 Capsules

Thorne Berberine Dietary Supplement 1000 mg 60 Capsules is a product from Thorne, 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.

80/100 overall — Verified tier (70–84 band). Per-dimension breakdown: Evidence 82, Formulation 82, Manufacturing 82, Transparency 78, Safety 75, Sustainability 55. Scored as of 2026-08-24.

Thorne Berberine 1000mg per capsule. Thorne is the practitioner-grade reference brand — NSF Certified for Sport on many SKUs, rigorous internal QC, published third-party COA on ingredients. Berberine at 1000mg per cap is ideal for the studied protocol (500mg TID with meals = 1500mg/day; 1000mg/day is achievable in 1 cap = simpler adherence). 60-cap SKU delivers 2-month supply at 1/day or 1-month at 2/day. Held below Elite by (1) berberine sourcing / standardization % not confirmed at product name (should be >95% berberine hydrochloride via HPLC); (2) no absorption enhancer disclosed — berberine has ~1% oral bioavailability per pharmacokinetic literature (Liu 2010); Thorne's 1000mg dose is high enough to overcome this without an enhancer; (3) sustainability profile thin; (4) no NSF Certified for Sport designation on this specific SKU. Would move to Elite 85+ with published third-party berberine assay + NSF sport cert.

Strongest: Evidence at 82/100 (quality of published RCT support for the active ingredients at the label dose) and Formulation at 82/100 (dose adequacy, bioavailability form, and ingredient redundancy). Weakest: Safety at 75/100 (adverse-event profile, interaction risk, and dose ceiling) 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 Elite 85+ with published third-party berberine assay + NSF sport cert.
