Exocyan Cran
Also known as: Exocyan Cran, Cranberry extract, Vaccinium macrocarpon extract
Overview
Exocyan Cran is a branded cranberry extract supplement derived from the American cranberry fruit (Vaccinium macrocarpon). It is specifically standardized for proanthocyanidins (PACs), which are the active polyphenols believed to be responsible for cranberry's beneficial effects, particularly in urinary tract health. Traditionally, cranberries have been used to prevent urinary tract infections (UTIs). The primary use of Exocyan Cran is the prevention of recurrent UTIs, especially in women and other susceptible populations. Its key characteristic is its high concentration of PACs, which work by inhibiting bacterial adhesion in the urinary tract. Research on cranberry extracts is extensive, with numerous systematic reviews and meta-analyses supporting its efficacy. While the quality of evidence is moderate, it consistently indicates that cranberry products can help prevent UTIs, especially when standardized for PAC content.
Benefits
Cranberry supplementation, particularly with products like Exocyan Cran standardized for PACs, offers significant benefits primarily in the prevention of recurrent urinary tract infections (UTIs). Research indicates that cranberry products can reduce the risk of recurrent UTIs by approximately 15-18% compared to controls, with a statistically significant relative risk reduction of around 0.82 to 0.85. This effect is most pronounced when the daily intake of PACs is at least 36 mg. The benefits are particularly relevant for women with recurrent UTIs, children, and other susceptible individuals. While evidence for pregnant women is less conclusive, no severe adverse events have been reported. Compared to antibiotics, cranberry products may lead to fewer gastrointestinal side effects. The observed relative risk reduction, though modest, is considered clinically relevant for managing recurrent UTIs. Benefits are typically observed with consistent daily intake over several weeks to months.
How it works
Exocyan Cran's primary mechanism of action involves its proanthocyanidin (PAC) content. PACs work by inhibiting the adhesion of uropathogenic Escherichia coli (E. coli), the most common cause of UTIs, to the uroepithelium (the lining of the urinary tract). Specifically, PACs interfere with the bacterial fimbriae (P-fimbriae), which are hair-like appendages that E. coli uses to attach to host cells. By preventing this adhesion, PACs reduce bacterial colonization and the risk of infection. This action is localized within the urinary tract, meaning it does not exert systemic antibiotic effects. PACs have limited systemic absorption, and their efficacy relies on their excretion into the urine, where they can interact with bacteria.
Side effects
Exocyan Cran is generally considered safe, with no serious adverse events reported in high-quality clinical trials and reviews. The most common side effect, reported in some studies but not significantly more than placebo, is mild gastrointestinal discomfort. Uncommon side effects (1-5%) may include rare allergic reactions, though these are not well documented. No serious rare adverse events (<1%) have been identified. Regarding drug interactions, no major interactions have been reported. However, caution is advised when combining cranberry products with warfarin due to a theoretical risk of increased bleeding, although this interaction is not consistently demonstrated in clinical practice. There are no established contraindications for Exocyan Cran, but individuals with a known cranberry allergy should avoid its use. For special populations, evidence in pregnant women is limited; while no safety concerns have been reported, the efficacy in this group remains unclear.
Dosage
For effective prevention of recurrent urinary tract infections, meta-analyses suggest a minimum daily intake of 36 mg of proanthocyanidins (PACs) from cranberry extract. Optimal dosage ranges commonly studied in clinical trials are between 36 mg and 72 mg of PACs per day. There is no established maximum safe dose, as doses up to 72 mg PACs/day have been well tolerated in studies. Daily dosing is recommended for consistent preventive benefits, and the timing relative to meals is not considered critical. For consistent and reliable dosing, it is preferable to use capsules, tablets, or juices that are standardized for their PAC content, as the PAC concentration can vary significantly in non-standardized products. The efficacy of Exocyan Cran depends on the excretion of PACs into the urine, as their systemic bioavailability is limited.
FAQs
Is Exocyan Cran effective for UTI prevention?
Yes, Exocyan Cran is effective for preventing recurrent UTIs, especially when standardized to provide at least 36 mg of proanthocyanidins (PACs) daily, as supported by research.
Is it safe during pregnancy?
While no serious adverse events have been reported, data on Exocyan Cran's efficacy and safety during pregnancy are limited, so consultation with a healthcare provider is recommended.
How long until benefits appear?
Benefits from Exocyan Cran for UTI prevention typically appear after several weeks to months of consistent daily use, as observed in clinical studies.
Can it replace antibiotics?
No, Exocyan Cran is a preventive supplement and cannot replace antibiotics for treating active urinary tract infections. It is not a treatment for existing infections.
Are cranberry juices as effective as extracts?
Extracts like Exocyan Cran, standardized for PAC content, offer more consistent dosing and efficacy compared to cranberry juices, which vary widely in their PAC levels.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC11635990/ – This meta-analysis of 10 RCTs involving 2,438 participants found that cranberry products providing ≥36 mg PACs/day significantly reduced the risk of recurrent UTIs by 18%. Despite moderate heterogeneity, the statistical significance supports cranberry's preventive role.
- https://pubmed.ncbi.nlm.nih.gov/34473789/ – This systematic review and meta-analysis, including over 2000 participants, concluded that cranberry supplementation significantly reduces UTI risk in susceptible populations. It highlighted the importance of PAC doses and formulations, with trial sequential analysis supporting the findings.
- https://www.cochrane.org/evidence/CD001321_cranberries-preventing-urinary-tract-infections – The Cochrane Review, encompassing 50 studies and 8,857 participants, found that cranberry products reduce symptomatic, culture-verified UTIs in women and children. However, it noted no significant benefit in elderly or pregnant women and highlighted heterogeneity in PAC doses, classifying evidence certainty as low to moderate.
