Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.
These calculations describe our scoring method. They are not a recommended dose or proof of benefit from this product.
Evidence gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Safety caps applied after weighting.
This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.
This Pure Encapsulations Berberine UltraSorb scores 6.2, making it below the site average. It delivers 550mg of Berberine, 61% of the studied range low edge (900mg) with grade A evidence (strong human trial data). The quality transparency (5.0) is limited by the lack of third-party testing. At $4.68/day it's among the more expensive options in Metabolic.

Uses the patented Berbervis berberine phytosome at 550mg, a lower absolute mg than the 1,000-1,500mg/day used in classic berberine RCTs, but the phytosome technology is intended to close that gap via improved absorption; the bioavailability claim rests on one company-cited PK study.
