Cranberex logo

Cranberex® is a concentrated (200:1), standardized extract that delivers Cranberry’s most active constituents: the unique A-type proanthocyanidins that don’t occur in PAC’s from other tannin-rich foods. [1]

Cranberex® contains 15% A-type PAC’s, as assayed by BL-DMAC, the method now endorsed by USDA, The Cranberry Institute and Rutgers University). [2]

It is this high concentration of A-Type PAC’s that connects Cranberex® to the latest clinical trials that demonstrate the ability of cranberry PAC’s to support urinary tract health.

Cranberex®: The Power of Oregon Cranberry

  • Pure whole berry Oregon Cranberry extract (200:1)
  • Comparative testing shows 10 – 15 times more active constituents than leading raw material brands*
  • Test results from Rutgers University show exceptional anti-adhesion activity, as compared to other brands*
  • Levels of ‘A-Type’ PAC’s in Cranberex™ correspond to most effective clinical trials of Cranberry extracts with a dose of 240mg – 480mg. [3]

Now available as powder, or encapsulated and bottled to your own formula.

The Clinical Studies and Science Behind Cranberex™

1 - In-Vitro Anti-Adhesion Activity (AAA) data from Rutgers University*

This in-vitro study compared the AAA of Cranberex® with nine other brands of cranberry extract (raw material and finished products). In this study, Cranberex™ met the anti-adhesion criteria at a concentration of only 0.23mg/mL. The next most potent brand required a concentration of 60mg/mL to achieve the same anti-adhesion result. The study concluded that Cranberex™ had excellent anti-adhesion activity.

2 - Ex-Vivo AAA study from Rutgers University*

This study, was designed to test AAA activity in the urine after consumption of standard dosage of Cranberex.® The study found that AAA response increased rapidly in all participants 3 – 6 hours after consumption of Cranberex®. Half of the participants achieved 100% or significant bacterial Anti-Adhesion Activity, while half achieved 50%, resulting in an average of 75% AAA. (see fig 2).

3 – Cranberex™ dosage level

The recent, multicentric randomized, double blind clinical trial clearly affirmed a bacterial anti-adhesion effect in urine, based upon 36mg/day of cranberry PAC (by BL-DMAC method) [3]. It also reported that effectiveness was dose-dependent, prolonged up to 24 hours with 72 mg of PAC, and increasing with the amount of PAC (by BL-DMAC method) consumed.

4 – Comparative potency testing

Tests that compared PAC levels in Cranberex™ with five leading finished product brands, showed a far greater potency in Cranberex™ (see fig 1).

5. The Need for Premium Clinically Tested Cranberry Extracts

UTI’s are one of the most common bacterial infections accounting for 10.5 million visits to doctor’s offices each year, and costing an estimated $3.5 billion per year in the US alone [6]. Some estimates place the percentage of antibiotic resistant cases at up to 10% of this number. As a result, many people are looking for alternative, naturally based ways to support UT Health. The science behind Cranberex® makes it ideal for those seeking health based solutions.
