Berberin UltraSorb
How we scored this product Show the full breakdown
Bevisning 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. Säkerhet 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.

Redaktionellt notes
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.
Why this scored this way
This Pure Encapsulations Berberin UltraSorb scores 5.7, making it below the site average. It contains 550.0mg of Berberin, which is only 37% of the 1500mg trial dose 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.
What drives the score up
- Dose-evidence score of 6.4 shows decent alignment with trial doses.
What drags it down
- Overall dose is only 37% of the trial dose across ingredients.
- Berberin (550.0mg is 37% of the 1500mg trial dose) is significantly under-dosed.
- No third-party testing, which caps the quality transparency.
- Quality transparency of 5.0 is below the site average.
- Limited consumer feedback (community score: 6.0).
Why you'd choose it
- You want Berberin from a Pure Encapsulations product.
Why you might skip it
- You want third-party verified purity.
- You want a product with a publicly available CoA.
- You need a full trial dose of berberine (this product under-doses it).
