What it is & primary uses
A simple sugar marketed to prevent recurrent urinary tract infections.
Main benefits
- Earlier small studies suggested possible benefit.
- A large placebo-controlled primary-care trial did not reduce recurrent medically attended UTI.
Studied protocols
Research doses are grouped by outcome. They describe study designs—not a personal prescription.
2 g/day studied; no established preventive dose
- Study duration
- Commonly 4–12 weeks; protocol and outcome vary
- Interpretation
- A large placebo-controlled primary-care trial did not reduce recurrent medically attended UTI.
04Food sources & equivalents＋
Can food provide a studied amount?
Small amounts occur in fruits; not at trial-level isolated doses can provide related dietary exposure, but food and extract milligrams are not automatically interchangeable.
Dietary exposure; verify composition before comparing with a studied supplement dose
- How this was estimated
- Dose Radar compares the declared active ingredient with official composition data or the studied standardized extract—not with marketing names.
- Important limitation
- Natural content, preparation, bioavailability and formulation vary. This comparison does not prove equal physiological effect.
Food equivalents compare ingredient mass using published composition values. They do not prove equal absorption, formulation, physiological effect, safety or personal need.

With water
Adequate fluid supports administration and tolerance; the product-specific directions still matter.
- Practical approach
- Daily with water. Keep the formulation and daily total consistent with the evidence context shown above.
- Watch for
- Glucose monitoring context in diabetes
Meal guidance reflects human pharmacokinetic, clinical, official-label or evidence-review sources where available. A food pairing can change absorption or tolerability, but does not make a supplement necessary, effective or safe for every person.

An unlisted pair means no established pair-specific interaction was identified in this review—not proof that every dose, product or person is safe.
This is not proof that every dose, product or user context is safe. Medication and condition checks still apply.
07Research notes＋
Insufficient evidence for the stated context. A large placebo-controlled primary-care trial did not reduce recurrent medically attended UTI.
The displayed amount comes from human research or an official evidence summary. It is not a personalized prescription, and formulation can change whether the comparison is valid.

Podcast and practitioner statements are clearly separated from research. They may explain practice or emerging ideas, but do not prove efficacy.
