Cranberry Fruit Extract
Also known as: Vaccinium macrocarpon, cranberry extract, ACE (aqueous cranberry extract), cranberry anthocyanins
Effective Dosage
No established dose (insufficient research data)
What the Science Says
Cranberry fruit extract is a concentrated form of compounds — especially anthocyanins and other antioxidants — found in cranberries. Lab research suggests these compounds have antioxidant properties and may play a role in reducing risk of urinary tract infections, cardiovascular disease, and diabetes, though none of the provided studies tested these effects in humans. The available research focused on using cranberry extract as a tool in nanoparticle manufacturing and on how anthocyanins are released from gel formulations — not on direct health outcomes in people.
What It Doesn't Do
No clinical trials in the provided data prove it prevents UTIs. No human evidence it fights cancer. The nanoparticle studies showing antibacterial or anti-cancer activity were lab experiments — not human trials. Don't assume lab results translate to swallowing a capsule.

Absorption & Bioavailability
Unknown — the only absorption-related data in provided studies examined anthocyanin release from gel formulations in lab conditions, not human absorption. Real-world bioavailability in humans is not established by the provided papers.
Red Flags to Watch For
- No clinical trials in the provided research — all three papers are lab-based studies, not human health trials
- Marketing claims about UTI prevention, heart health, or cancer risk reduction are not supported by the provided evidence
- Nanoparticle studies using cranberry extract as a chemical reagent are frequently misrepresented as evidence of health benefits
- Over 1,000 supplement products registered in NIH DSLD despite a near-total absence of clinical trial data in this dataset
